Immobiliser Systems

An immobiliser is an electronic security measure that deters thieves from starting your vehicle. It operates by sending an electronic signal from the car to your key each time you attempt to start it. The electronic chip inside the key responds by transmitting a unique code that must match the one of the vehicle in order for it to start. If the codes don't match, the engine will shut down immediately and prevent theft of your car.

Modern smart keys and fobs come with an embedded transponder that stores electronic security information in a format that cannot be easily copied. When your key or fob is inserted into the ignition, it transmits this code to a device within the ECU.

If the codes don't match, your engine won't be able to start - even if someone tries to short-circuit the ignition circuit.
