Transponders are electronic chip that has Non-Volatile Memory (NVM) that has a set of windings (very fine wire twisted around a tube) that resemble ones in an electric motor.

An immobiliser system is a digital security device that prevents thieves from starting your car. It operates by sending an electronic signal from the vehicle to your key each time you try to start it.

If the codes do not match, the engine will immediately shut down to prevent theft.

Modern smart keys and fobs come with an embedded transponder which stores electronic security information in a format which is not easily copied. When the fob or key are inserted in the ignition, they transmit this code to the ECU. The ECU is able to compare this code with the one that is stored in its memory, and it activates both the fuel system and the ignition circuit if they match. If the codes don't match, the engine won't start - even if a burglar tries to short-circuit the ignition circuit.
