Tell me - what is the system incinual access The car, as it works and how to protect the car with this system from theft.
What it is?
The invoice system is the contactless authorization of the machine owner on the key or an additional label of the immobilizer of the security system. Those. It came to the car, he recognized you and unlocked the doors, sat down and just pressed the button to start the engine. This system (Keyless Entry, Smart Key, Keyless GO) is present on premium cars or in additional options Machines of medium or budget classes.How does it work?
As soon as the driver comes up to the car and press the button on the door handle, the machine "wakes up" and starts the key dialog:- Hi, I am a car x with the Z identifier. And who are you?
This message is transmitted to the air purity of 125 kHz, and if the keychain key is near and understands the query language, it immediately responds with a machine, using its operating frequency (433 or 868 MHz). Moreover, it corresponds to a cunning digital combination generated by an individual encryption algorithm: - Hi, I'm your key! Response code ZXY56.G477.Q106.
An attacker will need a special repeater ("Fishing"), which costs tens of thousands of Euro and an assistant, which should be near the key, i.e. near you. When the corner presses the opening of the machine, the repeater signal is transmitted to the assistant device, which is already communicating with the alarm keychain. With the help of such actions, any car can be treated.
We give an example of the hijacking. You panicked the car near the shopping center, closed it and entered. The attacker number 1 is suitable for your car, and about you is an attacker No. 2 with a repeater of the signal signal of your key. The car at this moment identifies that you are supposedly located next to and opens. The attacker number 1 sits into the car and leaves.
How to deal?
There are firmware that will change the signaling code to another, which means they will be out of reach of repeaters. Cost from 5 to 20 thousand rubles. Or hide the alarm keychain into a metallized foil screen is a simple but effective way.
Household foil roll is taken, wounds to the width of the pursuit. The resulting square fold in half, once again in half. Four-layer square fold diagonally, put the key and sweep the corner. It is more convenient to put a bundle in the jacket unlike the iron boxes.
If speak about reliable defense From the hijacking, whatever modern "signaling" was not, you need to additionally install mechanical anti-theft, such as steering blocks and boxes. With them the protection of the car will be more reliable.
WITH mechanical systems The protection is lost the meaning of the "free hand" system - you need time to install and snap the mechanical lock. In addition, they save from the hijacking of the car, but not from theft of things in the cabin. Another thing is an extra label that works in another range. And on another algorithm than a regular system of invisible access. You can store it next to the documents. You can install an additional label in a professional anti-theft service.
Another method is to refuse when buying a machine from the "Incinual Access" function. In the old manner to use the usual key, but the nerves will save, without fear for the hijacking.
Standing at the sidewalk machine identified me for a couple of steps. Included the lighting of the cabin, opened the lops mirrors and reacted to the outstretched hand with a characteristic click of the central lock. I start the engine, I'm touched - and notice the warning inscription on the display: "Key Not Found". That's right, I really don't have a key from this car. And it was not. But there is electronic deviceallowing you to open and start cars by telepathic methods - at a distance. The hijackers call it long hand.
Have you already been riding on cars with a "golden key"? Those that automatically puts the car on guard, opens the doors and allows you to start the engine with the button without getting the key chain from the pocket? Cool thing! The system is so smart that now the usual ignition key is that the stone ax. By industry terminology, such systems are called PKES (Passive Keyless Entry and Start - "Passive Incinual Access and Engine Run"), and in a simplified form, their work looks like that. As soon as the driver comes up to the car and presses the button on the door handle (they can stand a touchpad or an electronic target, reacting to the hand brush), the machine "wakes up" and starts the key dialog:
Hi, I am a car x with electronic number Y and z code-identifier. And who are you?
Left "emulator", and on the right - "reader". Inside these boxes are hidden receivers and transmitters for three ranges (125 kHz, 433 MHz and 900 MHz), strip filters, amplifiers, processors and lithium-polymeric batteries of high capacity. Brown Kant, encircling one of the blocks, is a frame antenna. After powering on the power, the blocks are installed between themselves a high-speed data transmission channel, which allows you to relay the "key" requests for the car and remotely accept the label answers. The creators of the criminal radio suitable are well understood in issues of electromagnetic compatibility: when working long hand, you can talk on mobile phone Or, on the contrary, include cellular interference generators for locking GSM monitoring systems
This promise is transferred to the air on the "transponder" frequency of 125 kHz, and if the keychain key is near and understands the query language, it immediately responds with the machine, using its operating frequency (we have 433 MHz or 868 MHz in Europe). Moreover, it corresponds to a cunning digital combination generated by an individual encryption algorithm:
Hi, I'm your key! Response code: x123.y456.z789.
To exclude electronic lines (reproduction of pre-recorded parcels, transmit code via cellular channels or mobile Internet), the response from the electronic key must go in real time (the account delays is carried out on nanoseconds), so any "audio spectacles" and attempt to open the car " Under Phanery "doomed to failure. But…
The criminal vulnerability of PKES systems was spoken in 2011, when the team of Swiss programmers demonstrated the "elongation" method of the "car key" communication channel. The technology was named RELAY STATION Attack. It is funny that by that time the Russian hijackers have already enjoyed such devices (AR No. 8, 2011). And this summer in my hands were hit by two radio suites.
The first is designed for the hijacking "invincible" toyota cars And Lexus, released until 2013, and the second "lengthens" the Intelligent Key Car Access Systems of the Nissan and Infiniti of the current generation. Each long hand consists of two blocks: "Reader" and "Emulator" - which are easily placed in a small shoulder bag. After switching on, the blocks are installed between themselves a high-speed data transmission channel, which allows you to relay the "key" car requests and remotely accept the tag responses.
Sounding antennas at 125 kHz are installed along the perimeter of the body so that their diagrams do not overlap. Thanks to this, the car always knows where the key is answered, and allows the execution of only "geographically tied" teams. For example, the engine will start if an antenna in the backrest of a driver's seat is activated in the key radio exchange, and the trunk will open only when the key survey from the rear sector is successful
I opened your friends for your friends. First, I waited until the right owner parries the car, comes out, closes the door, looks back ... Now, keeping the "emulator" in the bag in a bag, go to driver's door "And at that moment, when my accomplice with the" reader "approaches the owner of the car (we coordinate your own actions by phone using innocent verbal turns), press the button on the door handle. The car issues a search query, the "emulator" accepts it, demodulates, strengthens - and immediately transfers the accomplice by radio. Its equipment produces reverse actions - and "polls" the key in the owner's pocket. Grabbing the response sending, the "extension" the same way sends it back - and via the "emulator" relay to the machine. True handle - and the door is hospitably swallowed!
Before starting the engine, the access system must request a key again (through an antenna in the driver's seat back), so I still keep the "emulator". We go! Now the key is not needed - neither a real nor "emulated": the motor will work until I stop it myself!
But what about the ban on holding a "radio spectacles"? The chip is that the information between the blocks is transmitted without digital signal processing, the direct transfer of the spectrum, and this allows you to put in the time limit reserved by the car's access system to the key dialog.
Here is my catch. Sedan Infiniti Q50, Nissan X-Trail, Nissan Pathfinder., Toyota Highlander, Toyota Land Cruiser. 200, Toyota RAV4 and Lexus RX 350. Not bad in a couple of days?
In the open area, the criminal boxes "clinging" their keys from drivers' pockets at a distance of one to three meters (the spread was determined by the location of the "reader", the antenna of which has a pronounced fire diagram and interference). The range of "crossing" code, that is, the distance between the owner and the car at the time of the hijacking, even in the city can reach more than three hundred meters. However, hijackers are usually reinsured, attacking the victim immediately after it leaves the parking place.
There are ways to get closer to a person, so as not to call him the eyes, how much: an elevator, rotating glass doors at the entrance to the hypermarket, the queue in the cashier ... You can even force the electronic tag to respond from the closed room. Going home, you put the keys ... Let's say, on the bedside table in the hallway, right? Iron entrance door, but blocks that are covered by the box, radio transparent!
I repeat: out of five attempts to "steal" the code from the car "through the wall" three were successful - Copperfield will envy! And if we build an external directional antenna (a suitable camouflage for it will be an open umbrella), then the range of transponder "shot" will increase at times. And, most likely, most of the hijacking expensive cars Country areas are carried out.
Toyota / Lexus radio unit blocks are collected from standard enclosures for radio-electronic devices. Cards have antistatic coatingThe elements with console mounting are fixed with screeds and a thermoclaim, and the power is connected through reliable power connectors. Marking with key elements of the circuit is removed by the mechanical method (it complicates the copying of the device by the reverse engineering method), and the loose connector of the radio station hints on the ability to use an external emitter. Traces of the national affiliation of this device we did not find but some technological features Support the idea that the radio subsistence is assembled in one of the countries of the former socialist
Have you already looked out the window, frightened for your car? And today's travelers in the elevator remembered? It only consists that to upset the key's code repeater can only afford a steady criminal grouping: there is such a thing from ten to fifty thousand euros. The price variation is determined by criminal marketing, because the manufacturer of repeaters does not make sense to sell the universal "openwright" with hijackers. As a rule, a hardware part is proposed with a specific firmware, "formatted" under the system of car access of a certain brand. And then the program updates come out for cars of fresh years of release, pay for which it is necessary separately. Familiar approach, right? And if you believe the manufacturer's advertising materials (the ends are easily on the Internet by key requests), you can buy any repeater - at least for Renault, even for Bugatti, - so what is the problem, alas, global.
What to do to tie their long arms hijackers?
Cut the Keyless Go system, pulling the battery from the key! (Secret: With documented deactivation of PKES, some insurance firms offer the owners of criminogenic machines. Preferential tariffs for the risk of "hijacking".) But then you have to put something in return. If you decide, in no case agree on a bilateral bond security system operating in Slave mode: in fact, this is analog standard system PKES and the same "extends". An intelligent recipe against the Relay Station Attack is to disable the standard radio channel and transfer the SMARTKEY module to a third-party block managed by its mark. Car defense specialists are asking for such a service of 15 thousand rubles. The "intellectual" module of protection, analyzing the radio setting around the car, detecting the operation of the radio suitalinator and can resist it. It costs about 8,000 rubles.
In the meantime - hide the keychain from the car in the Faraday cage: a case or a metal case (foolen) screen. Such a refuge for the "golden key" can be done by itself - at least from the cigarette pack.
This is a sample of the "handwriting" of the repeater for the hijacking of Nissan and Infiniti car, taken by a professional analyzer of the Agilent Technologies spectrum. The signal at a frequency of 902 MHz is a radio station that serves to transfer encrypted packets between the long hand blocks
Unfortunately today in Russia, as well as around the world, the number is growing. How then, the car owners can protect their cars from intruders who have long been used for the hijacking, which is able to easily bypass even the newest innovative automotive security systems?
Car theft equipped with an invisible access system (Keyless GO), a relatively new phenomenon. But despite this number of car grows with contactless system Access grows in geometric progression. The most interesting thing is that the attackers easily invigrate even new and expensive premium cars, which are equipped with the words of automakers, the most advanced protection technologies. For example, look at the fresh video where you can see how criminals.
By the way, the growth of car grows around the world (in our country there is also an increase in car theft) is primarily due to the fact that every year more and more vehicle equipped with a system of comfortable access that uses contactless key-trinket.
Why modern carsmobiles equipped with the most innovative security complexes have become much vulnerable to their predecessors? The race of manufacturers is to blame. After all, you can agree that the invincible access system is very convenient, it allows you to remove the machine with protection without using the key and without pressing the buttons on the key chain.
How is the car hijacking with an invisible access system (Keyless GO)?
The criminals use the vending of the car without a key, i.e. Using the relay of the signal of your contactless key to a special radio, which the attacker holds next to the door of your car.
In principle, this kind of theft is based. At the moment, this electronic equipment can be easily found on the Internet and purchase.
How do hijackers act, who have acquired a similar repeater? First of all, most often they are looking for the so-called "sacrifice" next to residential buildings, where cars are usually parked at night. Further, criminals check all cars with one goal, find the car equipped with such an invisible access. In more detail about the technologies of car hijacking with invincible access to the salon ,.
It's easy enough to do it. The point here is what. Most are equipped with a start / stop engine start button. You understand yourself, to find out whether your car is equipped with such a system of invincible access to a few seconds.
Next, criminals are divided. One with a radio receiver remains at the car, and the other is sent to the residential house with one goal, catch the signal of your contactless key, which is constantly empty by a low-power radio signal.
As a rule, most of the hijackers first go with their radio under the windows or balconies of residential buildings. After all, many of us put the keys to the car in the bedroom, the windows of which go to the courtyard, where the car stands. Thus, the chance to catch the signal under your windows the criminals have. Unless of course you do not live very high.
Also, criminals can go into the entrance to fix the same radio chain radio chain, which extends to the door of the apartment. So much so, through the door, many car owners put the key on the bedside table or on the shelf in the corridor of their apartment, before the inlet door.
After catching the radio chain radio signal, a radio drive radio receiver with a radio amplifier enhances the signal and transmits it further into the radio fleet on a special channel. And as you probably guessed, this radio signal is directed to the street, where there is already another hijacker next to the car, holding a special radio repeater radio, which, taking a radio chain-key radio signal on which it takes security system car.
As a result, the burglar system of the car recognizes the original key of the car and will naturally remove the car with protection.
The second and most common destinations for car grows with an invincible access system is parking from shopping centers and supermarkets. In this case, one of the criminals go straight out of the owner of the car, with the aim of catching the radio signal of the contactless keychain. The second hijacker is already at the car and waits for the transmission of the desired signal to open the car. After all, the attacker directly in the car only remains that it is to press the STOP / START button and start the engine, because the security system has already removed the car with protection.
If you can explain everything in simple, then you can tell. The radio itself, who keeps the hijacker next to the sacrifice, specifically becomes the native key of the car and actually deceives him. Indeed, in this case, the car alarm thinks that next to it is the original key of the owner.
The whole process of theft may take only 60 seconds. This type of hijacking is one of the fastest and simple for automotive connectors, since in this case they do not have to hack the door locks and break the ignition lock, but simply use special equipment for the deception of the immobilizer. It is noteworthy that the intruders themselves in this case are the risk of small, since such a hijacking occurs in complete silence and without the risk of signaling response.
How to avoid car hijacking with Keyless GO?
This type of hijacking can scare any car owners with contactless access in the car. After all, this is the high-tech type of hijacking from which it seems to be protected very hard or almost impossible, unless of course not equip the car with additional types of security systems. But in fact, not everything is so sad. There is always from the contactless hacking. All of them are not expensive and low-cost, in contrast to the installation of additional mechanical security complexes or installation of an additional second alarm.
Protect the key itself from your car
To protect yourself from this type of hijacking, you should directly, which will not allow hijackers to catch the radio signal of your contactless key.
First, we keep the contactless keychain from the car away from the entrance door and away from the windows, especially if the windows of your apartment (at home) go to the courtyard where your car costs.
This will allow you to minimize the likelihood that the hijackers will catch a radio signal and strengthen it, thus handling the signal on the radio amountering next to the machine.
Secondly, you can purchase a special case, a Faraday package or a car key storage box that suppress the radio signal transmitted by contactless key.
Including you can use just foil and wrap the key into it, which can also drown a radio signal. True, we want to note that all these things do not guarantee 100% of the radio signal suppression.
In the network you can find and see the victim of a lot of experiments, where many ways to suppress the key radio signal are not triggered. In order to be sure, for example, in the special cover you are used for a contactless key or in the Faraday package, which according to your principle should block the keychain radio signal, you need to approach the machine and simply check, and whether the key will recognize the combustible system of the machine. Make several tests. If the car does not unlock the doors, then it means it does not pass through the protective layer of the cover or package.
Is it possible to disable the contactless key Keyless GO?
Yes, you can. Many cars have the ability to disconnect the Keyless Go system, which provides you with comfortable access to the salon without using the key. To do this, refer to the car operating manual or to the technical center where experts will disconnect you the operation of an invincible machine access system. Unfortunately, turn off the Keyless Go system is not in every car, and not in each of them to do it will be so easy. Nevertheless, most cars can do it all the same.
Mechanical protection of the car
You can also purchase an additional security system. for example better decision For you there will be a mechanical protection - i.e. Castle on the steering wheel, on the gearbox block, on the brake pedal blocker, etc. etc. Including you can buy a special clamp for the wheels.
By installing mechanical protection on the car and thereby create difficulties for the hijacking of your car. After all, getting access to the car interior with special equipment, they, i.e. hijackers will face mechanical protection, breaking the extra time to break. Most likely, in this case, the hijackers are simply retisted, since new and unjustified risks appear for them.
How else can you protect your car with the Keyless GO system?
You understand that 100% of the protection against theft does not exist (so that you are not promised and did not speak in various companies in the installation of anti-theft systems). The main thing is to remember that the risk of car theft is always present, even when he literally the whole stuffed with various security and complex equipment.
After all, the task of each car owner is to simply reduce the risk of hijacking, thereby foresess everything possible methods protect your car from encroachment by intruders.
First, we advise you initially be always vigilant. When you go out of the car and go for example, shopping in the supermarket must remember, in order to hug your car to criminals, you need to catch the signal of your key. And in this case, there must be a person who is usually masked in a backpack or a sports bag. Nevertheless, in any case, a person who is close to you will be very suspicious and in some extent insecure, you can easily notice it.
Secondly, we advise you to install alarm system in your car satellite system Tracking and with a monitoring system using cellular communication. Yes, many of you may argue that such complexes are also easily and quite skillfully bypass the intruders themselves applying other and more expensive equipment. But still, in this way, in any case, you increase the chances for yourself that your car will not be stolen.
Why do the automakers do nothing with Keyless GO technology?
It may be an erroneous opinion that automakers are consciously do nothing and will not improve the technology of invincible comfortable access to the car. After all, they know about the massive hijacks of cars with this system worldwide.
But in fact, and despite the fact that the problem of such hijacks has appeared quite a long time, many automobile companies have been developing new Keyless GO systems with one goal only to prevent the hijackers to use the simplest equipment for relaying the contactless radio signal.
For example. Many automotive companies began experimenting with frequency, and some decided to equip cars with the latest softwarewhich is based on the technology of "artificial mind," which he himself knows how to distinguish between the original key from the retailer of the hijackers.
Unfortunately, such innovations of automakers are not cheap and, as a rule, they appear only on expensive premium cars. Although it is not a fact if you return to the beginning of the article and look at the video, you will immediately understand that even a new and very expensive Mercedes can easily be saccked with special radio equipment. And this is all taking into account the fact that Mercedes company is more than once in the network and on television praised its newest security system.
Thus, it is possible to state, to date, the problem with the system of contactless access to the car has not yet been solved, the more globally. After all, in most inexpensive cars Today the standard Keyless Go system is installed, which is easy to crack even very expensive equipment. I also want to note that in recent years, radio equipment used by automotive connectors has become significantly cheaper, it has become easily accessible to purchase it on the network.
And since it is so, then each car with an invisible access system is located today in a large risk area. Therefore, each owner of such a car must necessarily make additional defense For your property, do not rely on a praised staffing security system about which probably more than once already spoke by the manager in the showroom. Remember that the Keyless GO system seriously vulnerable !!!
If you can do something in life, it does not mean that you must must To do. That is why there is no chewing gum, seasoned with venel or lar in the Vasabi sauce on our dining tables. The same applies to technology. There is a huge number of incredible things that we are able to technologically. But all these things simply do not make sense. One of these technologies is a system of invincible access to the car, which in recent years has become a fashion trend in the automotive industry.
The invincible access system has become a very popular function in many new cars. It allows the driver without using the key to open the door and start the car thanks to a small electronic key chain lying in your clothes pocket or in a bag that communicates with radio waves with your car, which allows you to open the doors and run the engine, etc. without key
In a sense, this is a wonderful technology that our grandfathers would largely consider magic and magic. You are approaching the car, and it is unlocked. You get into the car and without getting a key mark (keychain) from pants or jacket pocket, in the blink of an eye, you start the engine using the Stop / Start button and can. Very easy! If you were back in the past, even at the beginning of the 1980s, and showed such a system there, then many car enthusiasts would think in those years that you flew from another planet.
Although this technology makes the process of accessing the machine as easy as possible, the new technologies actually blinded all automakers in the world from real thinking, which is necessary to create real practical car. The fact is that it is always necessary to take into account the usefulness of a new technology, weighing everything "for" and "against". Always need to take into account how to work new technology In the car and it will be convenient for her to use people. With regards to infinite access technology, then the problems that this innovation system has is not technical. Here just, on the contrary, a purely technically, the whole system works in all cars well enough. In fact, there is a more global and deep problem associated with the fundamental concept, which is based on our relationship with you with castles and keys that have developed over many centuries.
Let me bring some examples. This year I with my colleagues tested several new Tyota Camry, with various engines and in different configurations. All machines on the test were equipped with an invincible access system. During the test drive, we did several stops and transplant to each other to compare various versions of cars. Contactless tags we left either in the car, or the key lay in the driver's pocket, as in real life. Do you know what happened during the testing process? Many of us have forgotten that we have a keychain that needs to be left in the car before transferring to another car. In some cases, someone at all escaped with the key from one car and sat in another for the test, completely forgetting about him.
Why no one noticed this? The thing is that we are not jamming cars while stopping for transplantation. And the system of invincible access allows you to drive in the car without a key or with a key from another machine, if it was originally started with the correct mark. That is, if you turn off the car, to start it again, you will need the original non-contact key.
Also recently my friend gave me a test new Mercedes With invincible access in the car. Sitting into the car, I, in order not to lose the key, decided to put it in an external side pocket of my sports bag, but I could not fasten the zipper and, turning back from the driver's chair, removed the sports bag on the back seat. See, at that moment the contactless key fell out of the side pocket and flew off under front seat. Then, closer to the evening, I got out of the car, took a bag with rear seat, Deciding to go to a cafe to drink coffee. Being confident that the car will automatically close as soon as I go away from the car, I calmly went to the coffee shop.
After drinking coffee, I, returning to the car (which, apparently, stood open all this time, as the contactless key lay under the seat), without a back thought I got behind the wheel and headed home, stopping for gas stations. Having arrived at home, I, not the glow of the motor, decided to get the key from the bag. What was my surprise when I did not find a key there. I had a panic. I started remembering where the key is the key. I was not even sure of 100%, which put the key in the bag and did not take it. It seemed to me that I had already got it and shoved somewhere. I thought that I lost it on the gas station, where it was refueling, not the gentle engine.
Naturally, if at this moment I turned off the engine and launched again, I would immediately guessed that the key somewhere in the car. But at that moment I had a panic, and I was afraid to turn off the motor, because in the absence of a key, I would not have started a car.
So, as you see, the problem of the invincible access system is that if you have lost the key in the car, you cannot find out whether the key is in the cabin or you really lost it, until you turn off and do not start the engine again.
One of my friends recently complained about inconvenience with contactless keys in their family. The fact is that he has two spouses identical car Toyota Corolla, which are equipped with an invincible access system.
Often, the spouses go in one car. My friend, sitting down to his wife in the car, sometimes puts the contactless key to his wife in a bag. Especially in the summer, when in his pocket to keep the key sitting in the car, uncomfortable. As a result, then they often confuse each other's keys, which gives them extra effort, because without an original key, the car will not even open. As a result, I have repeatedly seen how my friend, going to my car, went back home, because I did not take my contactless key.
Yes, as you can see, contactless keys in the car eliminate the entire routine associated with real keys. But nevertheless, contactless keys threatened another routine. In addition, even with a contactless key, you still have to do a certain ritual: open the door, press the "Engine start" button, which, as physical actions, does not differ from the rotation of the ignition key. Personally, I did not particularly appreciate the system of contactless access, despite the fact that to start a motor, I do not need to insert a real key into the ignition lock.
No, of course, if an invisible access system is installed in your car, then when you approach the car, the doors are automatically unlocked, which is very convenient and useful. But when it comes to starting the engine, then many drivers are desirable to establish physical contact with the car, inserting the key to the ignition lock. So, first, you always know where the key is, and secondly, you will never forget it at home and do not lose it.
In some cars, the contactless key can be inserted into a special connector, as well as rotate as a real metal key. For example, such a system is in many Mercedes cars, BMW and Mini. The key actually is a key chain in the key form that you must insert into a special connector resembling a USB port. By inserting the keychain into the connector, you must turn the key to run the machine.
True, usually such keys are used in cars without an invisible access to the car. But on some MINI cars such keys are used with the possibility of tailless door opening.
The usual system of invincible access to the car, which today has become fashionable and popular around the world, actually violates the cycle of the causes and consequences to which we are accustomed for many centuries using the keys and castles. The key comes into contact with the lock, opening it. Violation of this cycle is unusual to our brain. And at the subconscious level. Although contactless access to the car is still a truly comfortable thing, since the doors of your car when the auto owner approaches, in the pocket of which is a key label, open automatically.
But when starting the engine, it is preferable to use the classic method of interaction between the key and the castle to which humanity is accustomed for many centuries.
After all, the launch of the machine with a key without a key changes the fundamentally the entire system of human interaction with the machine and carries a number of problems that I wrote above. Physical real keys require constant contact with them so that your car supports its work. For contactless keys, the connection with the machine is needed only for a short time immediately before starting the engine.
And this is a problem. That is why when we all used the usual keys that were inserted into the ignition castle, we did not disturb us where the key is when the engine is headed. Naturally, if the machine works, it means that the key is in the ignition lock. In modern cars with invincible access you will often be worried about where the key is, because if you even remove it in the bag, in the glove box or any other place in the car, the engine will continue to work. As a result, the contactless key is easy to forget in the car and leave, without noticing that the car did not arise. Also the key tag is easy to forget the houses in the pocket of other trousers, etc.
As you can see new system I spawned new problems that we did not even think when we used the usual ignition keys.
Here for you the fact of starting the engine from the key is some kind of complicated action? And it is difficult so much that you dreamed about the engine start button. I think most car enthusiasts did not even think about it before. Believe me, all all satisfied.
But in the end, the automakers decided that without a system of invincible access to the car owners modern cars They will not be able to do. Agree, nonsense. This system, apparently, began to be used. automotive companies Only one goal is to increase the vacation value of the new car, which, of course, increases profits. car brand.. Plus, once again show consumers that their products correspond to the spirit of the 21st century.
I think in modern world everyone is in a hurry somewhere trying to bring out as possible more technology. But why? What's the point? We do not want our world today look like the worlds of Fantasta Aizek Azimov?
And imagine if someone will offer someone a key label for contactless access to the car in the driver's hand in the form of a microchip! The worst thing is that someone in the world thinks this technology to implement in the automotive industry. After all, it will stand out among others car Marks And to attract world presses and a lot of public to them.
But in fact, this technology will not be needed. It makes no sense. Just as it makes no sense in the system of contactless access in the car. At least as regards the start of the engine, I believe that automakers must return to us the ability to run a motor using an ordinary physical key that must interact with the ignition lock.
Also, in conclusion, I would like to remind you that the system of invincible access to the car is very vulnerable, and this is used by modern automotive drivers. The fact is that whole groups of attackers appeared all over the world, who specialize in theft of cars equipped with an invincible access system. The worst that manufacturers, introducing such systems on modern cars, in fact, simplified the task of hijackers, which are not even needed using the grabber code to intercept the alarm keychain signal, break the door lock and turn the ignition lock.
Now for theft, the criminals use special repeaters, which, intercepting the signal with contactless keys, amplify the caught signal, and then transmit it to the receiving radio receiver, which in turn relaims the signal to the car. As a result, the security system takes a native signal of the contactless key that can be far from the car at this moment. For example, with similar repeaters, attackers can pass the signal of your key when you are at work, in a cafe, restaurant, shop, cinema, etc.
You can read more about this method of hijacking in our following articles:
So, as you can see, in addition to new inconveniences created by the invoice system, a new technology, in fact, provoked the new kind Car heights around the world, noticeably simplifying the task for criminals. The worst thing is that such equipment, a relay signal of contactless keys, today can be collected for a penny by purchasing details on Chinese sites.
At school, I was taught that with communism, all kinds of constipation and keys will become unnecessary by definition. Homo Sapiens will be so conscious that he and the head will not come to know what is intended for another. And although the construction of communism is stopped (or temporarily suspended), the keys slowly begin to go down in history. But is it too early?
The first serial system of invincible access to the car still in the last century, Mercedes found, today almost everything is used. System names and specific circuitry can vary - Hands Free, Keycard, Comfort Access ... But the main thing is that the manufacturers have already taught us to this comfortable and simple access system: went to the car, opened the door, sat down, pressed the start button - and forward. The only requirement is to have a contactless key, the so-called label. Without it - no way. Or are there any options?
Rental without demand
Unfortunately, there are options. Recall that the label is such a microcircuit with an antenna. The car radiates a modulated high-frequency signal of high wells, and the label is captured at a distance of no more pair-troika meters. Having identified your car, she sends onboard anti-theft system Signal Unlock access to the cabin and allow engine start. The exchange of information usually goes at frequencies from 125 kHz to 2.4 GHz. Ignition lock, naturally, is missing: enough to start the engine start button. Leaving the car, the owner just slams the door, then touches the finger of the button on the door handle. All, the car is locked and put on guard! Now remember what a repeater is: this is a transceiver radio device, located at the intermediate items of radio lines, which enhances the received signals and transmits them further. For example, a television signal that is bearing enlightenment in distant mountain aul. If the repeater enhances the signal from the tag, then the machine will start listening not only to its owner, but also ... the owner of the repeater!
Caught an idea? No? Then here is the crime scenario.
They wrote a crime
Make a compact repeater to hide it in a small bag or portfolio, it is easy. And let the label lies in the master's pocket, no one is going to steal it. The criminal with the repeater is enough just to be a couple of dozen seconds next to the owner of the car. The rest will make his assistant.
An ideal place for a crime is the site near large supermarkets and entertainment centers. Machines - the sea, the people - the ocean. The owner closes the car and goes for purchases, and behind him in a pair of meters should be a hijacker with a repeater in the bag. As soon as they are removed for a respectful distance from the car, the offender gives a signal to its colleague - for example, calls him on a mobile phone. That in one movement opens the machine using the second repeater unit, a camouflaged, for example, under the usual radio, allows the motor and leaves. Communication with a real mark is no longer needed - the car, having lost it, will no longer stand.
And what remains in the pocket of the present owner, in fact turns into a black mark for him, on which it is written: "Sentenced to the removal of transport."
