Transponder chips are present in the key heads of almost all new cars built since 1995. They are used to disable immobiliser systems. The head of a key that includes a transponder chips can be removed to reveal a metal L-shaped key. A transponder-chip replacement key, also known as a fob is a process that involves multiple stages. It involves cutting the keys with precision and programming the chip to sync up with the vehicle immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire coiled around a tube) that look like the ones in an electric motor. The windings generate a coded message that the car can read. If the code is correct the car will start.

There are two types of transponder chips. One is known as the 80 bit, and the other known as a circle + (General Motors).

When the fob or key are placed in the ignition, they transmit this code to the ECU. The ECU will then check it against the code stored in its memory, and activates the fuel system and ignition circuit if the two match. If the codes don't match, the engine will not start - even if a burglar tries to short-circuit the ignition circuit.
