In most modern mechanical vehicles, immobilizers are installed to protect them from theft attempts. The operation of this security system is ensured by a chip built into the key, from which the car’s electronic control unit reads information when starting the engine. If the digital code does not match the data stored in the device’s memory, the car will not start. If you lose the car’s unlocking key, you will need to make a полноценный duplicate.
To do this job, it is not enough to simply cut the appropriate key configuration into a metal blade blank; it is also necessary to copy the electronic part of the device, which ensures the functioning of the immobilizer circuit.
Key making – a sequence of actions
The following work is carried out:
The geometric profile of the key blade is determined.
The chip parameters are determined.
The metal blade is manufactured; this is done using CNC machines.
Information about its compatibility with a specific car brand is written to the duplicate.
The prepared chip is installed in the key.
The operation of all systems is checked.
Making a new car key after losing the old one requires special equipment, professional knowledge, and skills to perform this work properly. The alphanumeric code from the duplicate’s chip is entered into the memory of the car’s electronic control unit using a programmer. This makes it possible to start the car’s engine by inserting именно this key into the ignition lock.
If the owner wishes, the immobilizer system can be disabled, but then the car will not be protected against theft and will become easy prey for criminals, since it could be started with any metal item that matches the geometric dimensions.
