In modern vehicles, equipped with new electronic keys (including contactless access keychains) have problems with opening the machine, if the device has a battery or battery, as well as with further engine launch. After all, there is not always a battery at hand. Therefore, many car enthusiasts face difficulties and do not know how to get into the car without the help of an electronic system of comfortable access. The fact is that many modern cars, instead of our usual keys, have electronic key chains to open and launch a car. What to do? We will try to tell you what to do and how to open a car ,.
What happens if the battery pack in the electronic keeper?
If your car is equipped with a system of comfortable access to the car, as well as a system of comfortable engine running, then yours, with which alarm system vehicle, Determines you as the owner of the machine. When you come to the car, and the signal that transmits the keychain starts to be in the view of the machine alarm, electronic system Opens automatically machine, providing the owner comfortable access to the salon without using a regular key, or without pressing the buttons on the alarm keychain.
Sitting into the car, your electronic keychain, continues to send an electronic signal to the car, telling the electronic alarm that you are the owner of the machine. That is why you can make a car without any problems using the Stop Start button. But for comfort, you have to pay possible difficulties with which any owner of a modern car can face. For example, if a battery or battery sees in your remote control, you will not only be able to get into the interior of the machine, but also to start the engine, since in that case your key without food stops sending the signal to the vehicle alarm unit.
As a rule, in this case, you cannot or can not start the motor. Even if you opened the door, in case of discharging the battery on dashboard Machines You will see the icon telling you that the key is not found. Therefore, if your machine does not have a ignition lock, then you will not head the car until you change the battery in the remote control.
In fact, fortunately there are ways to open a car with a served battery in the key, as well as even run the engine in some models. The fact is that the majority of automakers equipped electronic keys (key chains) with a hidden emergency key, with which you can not only open the door, but also start the engine engine. But, however, not everything is so easy.
The greatest difficulty is that 11 automakers, equipping electronic key chains from accidents with emergency keys, hidden on the door handles of the holes for keys. The worst thing is that in all car stamps Opening the machine with an emergency key occurs differently.
For example, brands such as Audi, BMW, Ford, General Motors, some models Hyundai., Jaguar, Kia, Lexus, VW and Volvo have hidden secret key wells for the emergency key.
We offer you instructions for many cars that will help you solve the problem in case of discharging the battery in the console to the car. Using our manual, you can open the car using the emergency key. Our publication series in the coming time will include instructions for opening and running the engine of the next brands:
Chrysler / Dodge / Jeep
Fisker.
Ford / Lincoln.
GENERAL MOTORS (Chevrolet / Cadillac / Buick)
Honda / Acura.
Hyundai / Kia.
Jaguar.
Mazda.
Nissan / Infiniti.
Subaru.
Volvo.
VW / Audi.
Today we publish the first instructions within the framework of the publication series, which will tell, how to open and mini, as well as how to run a motor without an electronic keychain, if the battery has taken.
Open the BMW door and mini if \u200b\u200bthe battery is discharged in the key.
In order to open the door of the machine in case of discharge of the battery in the electronic keychain, we need an emergency spare iron key that is hidden in your original car key chain. In order to get it out of the keyword, you must press a special button on the back of the keychain and extend the emergency key from the remote control.
This integrated key can be used to open. driver's door and. In order to open the door with this special key, you must insert it into a special hole, which is from below in the front driver's door knob.
Attention!
Many new car models do not have open hidden locks for the emergency key. Automakers B. last year began to hide the holes for keys under plastic door handles. Therefore, in order to open the door, you will have to damage the door handle, off pieces of plastic.
For example, the BMW X5 since 2014 does not have an open technological hole for opening the machine with a special key.
In order to open the door of the car using a hidden key, you must insert it into the hole (it is shown in the picture with an arrow) and press the door knob.
If your machine has a hidden lock for the key, then put the key to the place that is indicated in the picture by an arrow and press the key up. Plastic, hiding lock for the key goes off. Next, click on the key again and click on the door handle - the door will open.
How to start the BMW and mini engine if the key chain is discharged?
Some BMW and mini models in order to run the motor require the insertion of the keychain into a special connector, which is next to the button. If the battery keychain is discharged, then inserting it into the connector next to the Stop start button, the electronic system recognizes the electronic key chain.
If yours model BMW. And Mini does not require the insertion of the keychain into a special connector, then keep the key in the steering column area, as specified by the image arrow (see photo). Next, click the Stop Start button for ten seconds while holding the brake pedal.
Note: If you failed to try the engine to start the engine described above, then probably in brake system may be residual pressure. In this case, a warning icon may appear on the dashboard.
In this case, try to repeat the attempt to start the motor by clicking on the brake pedal, as stronger and press and hold the stop start button for 10 seconds.
Attention!!! Press the pedal is necessary until the warning disappears on the dashboard to press the brake pedal.
W. modern cars, almost all the ignition key is not usual, this is the so-called chip key. What it is, how to change in it. Recently, a very interesting letter came to the blog, I will not retell, but a person asks - how does the key chip? The question I seemed interesting to me and I decided to write an article on this topic ...
It is really outside on the key there are no fees, no contact groups and so on to apply it to any reader by car. There is a key that is inserted with a keyhole, but it is not contact Group! So what principle of work?
If you go into technical details ...
The car ignition lock has a specific frame that is connected directly to the immobilizer unit. When the ignition is turned on, the block submits the pulse to this frame and goes into read mode, that is, it starts listening to the response from the chip. In turn (from the pulse), the chip - the key is charging and begins to transmit the code sewn into it, transfers to this frame of the immobilizer. The immobilizer frame takes the code, and if everything is fine with the ability to start the engine.
If just ...
Present work very easy. Probably all (or many) have intercoms on the entrances. We approach a special key chain, the intercom read it and opens the door. This is an exaggerated example of a chip key and a car immobilizer.
It should be noted that without this chip key, the car does not start the immobilizer will not allow! It blocks various cars:
- Some cars have an immobilizer in the ignition lock itself and blocks various functions in the castle.
- Other immobilizer is built into the dashboard and operates certain car chains (for example, a chain of fuel pump)
- Third, the yimobilizer block is in the processionate space, and with the help of amplifiers can block the lock and chains at the same time.
As you can see the device and the principle of the chip key, it seems simple, but efficient. However, now many alarms with autorun disconnect starting immobilizer (In particular, with the help of an additional key that is placed in the car panel), I do not recommend doing this personally. Because the car becomes easier prey for hijackers.
And now a small video version of the article
That's all, I think the article was interesting. Read our autosite
In this article, I will tell you about how to do something on the likeness of the contactless key. The essence is that there is a transmitter sends a signal to the receiver built into the device you need. Move the transmitter to the device, and it starts working. This key range is about 5 cm. Basically it depends on the power supply unit of the key transmitter itself.Now let's see the device diagram:
The transmitter is a conventional blocking generator. Used the CT315 transistor, but others can also be used. Patient the contactless key scheme is permissible and from a 1.5 volt battery, but the higher the supply voltage - the greater the range. The only minus scheme is that to start the key, you need to close the base and collector for a short time. Key receiver. To begin with, we collect a simple receiver - a coil and a LED. Check if the SD works, you can go on.
List of parts for the device:
CT315 transistor or any other
AA battery
Wire 0.1-0.6mm.
LED for 3V, but I also glow on 12V.
Let us turn to the practical use of a contactless key scheme in everyday life:
We will make minor changes to the receiver:
- Diode Schottky with low voltage drop
- electrolytic capacitor 100mkf
- transistor of average power KT837, etc.
- power supply, you can use the 12V battery
- And the most important thing is the relay that will manage all connected loads.
Now a little about what this device does not earn - coils. The coils of the transmitter are wound on the pipe 5cm with a diameter, with a wire of 0.1-0.6 mm. The thicker the wire - the more current Consumption and Quality. L1 has 30 turns, L2 twice as fewer - 15Vets. Attention! Coils L1 and L2 dangle in one direction. If wrap in different directions - nothing will work!
The receiver's coil is desirable to have as many turns as L1.
But the layout of the contactless key assembly:
If you all collected correctly, the device does not turn on, try to close the collector and the base several times - everything should earn. In the process of experiments, I noticed that if you turn the coil with the LED - it burns or brighter, or dim. Also here you can demonstrate the principle of action of ferrite:
This is a ferrite from the radio. The LED is on the height of as much as 15cm! Therefore, the receiver can be easily hidden into the housing of any device, only the housing should not be made of metal. I think the use of such a device you have exactly. If not, then you can leave the LED, fasten the transmitter for example under the table, and on the table put a receiving coil - it will also be a very funny device. And you can play friends, as I usually do)))
