Immobiliser

Immobiliser

The immobiliser is an electronic anti-theft device. It is activated when the ignition key is removed and, via the engine control unit, largely prevents unauthorised starting of the car. The system uses a transmitter and receiver unit integrated in the ignition key (transponder). Whenever an attempt is made to start the engine, this transmits a new code to the car’s electronics. The immobilising is only cancelled if the key sends an appropriate authorisation code. New encryption technology protects the system against electronically copied vehicle keys. Note: No system can provide 100% protection against theft. If thieves possess the necessary skill and determination, they may be able to overcome the electronic immobiliser in individual cases.
