Immobiliser Systems

Immobiliser systems are electronic security devices which prevent thieves from starting your vehicle. It works by sending a signal from the vehicle to the key when you attempt to start it.

If the codes do not match, the engine won't be able to start - even if an armed robber attempts to short-circuit the ignition circuit.
