A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that has a set of windings (very fine wire wrapped around the tube) which look similar to ones in an electric motor. The windings are coded to create a signal for the car to read. If the code is correct then the car will allow you to start it.

Immobiliser Systems

An immobiliser is a digital security device that prevents thieves from starting your vehicle. It operates by sending an electronic signal from the vehicle to the key whenever you try to start it. The electronic chip in your key responds with a unique code that must match that in the vehicle in order to start. If the codes don't match, your engine will stop immediately, preventing theft of your vehicle.

Modern smart keys and fobs are equipped with an embedded transponder, which stores electronic security information in a format which is not easily copied. When the key or fob are inserted in the ignition, they transmit this code to the ECU. The ECU then compares it with the code stored in its memory. It then activates the fuel system and ignition circuit if they match. If the codes do not match, your engine won't start - even if an armed robber attempts to short-circuit the ignition circuit.
