Immobiliser Systems

An immobiliser system is an electronic security feature which prevents thieves from opening your car. It operates by sending an electronic signal from the car to the key whenever you try to start it.

Modern smart keys and fobs come with an embedded transponder, which stores electronic security information in a format which is not easily copied. When your key or fob is put into the ignition, it transmits this code to a receiver inside the ECU. The ECU will then check it against the code stored in its memory. It then activates the fuel system and ignition circuit if the two coincide. If the codes do not match, the engine will not start - even if a burglar tries to short-circuit the ignition circuit.
