An immobiliser system is an electronic security feature that stops thieves from starting your car. It operates by sending an electronic signal from your car to your key each time you try to start it.

Modern smart keys and fobs feature an embedded transponder chip that stores security information in a format that can't be duplicated. When your key or fob is installed in the ignition it transmits this code to a receiver in the ECU. The ECU then compares it with the code in its memory and activates the ignition system and fuel circuit if they coincide. If the codes don't match, your engine won't be able to start - even if a burglar tries to short-circuit the ignition circuit.
