Immobiliser Systems

An immobiliser is a security measure that uses electronic technology that deters thieves from starting your vehicle. It works by sending an electronic signal from the vehicle to the key each time you attempt to start it.

It then activates the ignition system and fuel circuit if the two coincide. If the codes don't match and the engine does not start, even in the event that the ignition circuit is short-circuited by a burglar.
