A transponder is a device that has Non-Volatile Memory. It has a set windings which are fine wires coiled around the tube. They look similar to those in an electric motor. The windings generate a coded message that the car will read. If the code is correct the car will begin to move.

Immobiliser Systems

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

Modern smart keys and fobs are equipped with an embedded transponder chip that stores electronic security in a format that can't be easily duplicated. When your fob or key is inserted into the ignition, it transmits this code to a receiver in the ECU. The ECU examines the code against the one stored in its memory and activates both the fuel system and the ignition circuit if they are compatible. If the codes do not match and the engine does not start even when the ignition circuit is damaged by a thief.
