All modern cars are equipped with immobilizers. This
anti-theft complex prevents unauthorized starting of the car engine when trying
to steal it. Depending on the model, it is not possible to activate the power
plant or turn it off after a certain period of time. To know more, check out: car keys made
The principle of operation of a key for a car with an immobilizer
The operation of the system is based on receiving a signal from a key, which contains a transmitter chip and an antenna for signal amplification. The receiver is most often located on the ignition switch, which makes it much more difficult for the hijacker to access it.
Despite the seeming simplicity of the system, making keys for cars with an immobilizer is a complex process. The main problem lies in the frequency of the control signal, which is individual for each model of the protection system. Therefore, to increase the safety and comfort of car operation, you should adhere to the following rules:
· Keep a copy (or several), do not use them;
· Be sure to check for a master key. With its help, you can independently register a new one in the immobilizer;
· In the event of even minor malfunctions of the system, you must contact a car service. A breakdown of the car protection may prevent the engine from starting even with the original chip.
But what if you lost your car key? In this case, you can try to make a duplicate yourself or use the services of a specialized car service.
Manufacturing technique
To increase operational safety, the transmitter (transponder) is located in a special protective flask. It has a glass shell to prevent the data being read. The control takes place using an electronic unit.
To avoid inaccuracies, it is recommended to purchase a ready-made kit. Its cost depends on the car brand and model. On average, a case without a flask will cost from 400 to 800 rubles. The cost of a transponder can be 300-400 rubles. Slicing services - from 500 rubles.
Using a master key
After the selection of components and the assembly of the structure, you can proceed to registering the key in the immobilizer. The best and fastest option is to use key master.
The master key is used to configure the immobilizer. You can also use it to register a new one. Detailed instructions for performing this procedure depend on the specific car model. Manufacturers make it as complex as possible to improve safety. Reconfiguration instructions are indicated in the passport of the machine. But if there is none, there are many training videos or text materials on the Web. With their help, you can independently register a new key in the immobilizer.
Most often, the procedure consists of the following stages:
· Insert the key master into the ignition lock several times;
· Open and close the car doors;
· Alternately pressing the brake, gas and clutch pedals.
If everything was done correctly, the LED indicator will light up. You can then insert a new key with a pre-cut sting.
Specialized car service
In rare cases, the key master can be lost, and there are no other working duplicates. The only way out of the situation will be the services of specialized companies. It should be remembered that making keys for vehicles with an immobilizer without interfering with the system will be impossible. This will require special equipment.
Then the craftsmen dismantle the ignition lock and reconfigure it to adapt new duplicates in the system.
