Nearly all new cars made since 1995 include transponder chips in the key head that allow it to deactivate the immobiliser system. If you've got a car key with a chip, the head is covered with a plastic cover which can be pulled off to reveal an L-shaped metal key. A transponder chip replacement key or fob is a process that involves multiple stages. It involves cutting keys precisely and programming the chip to make it sync with the vehicle's immobiliser.

Transponders are electronic device with Non-Volatile Memory (NVM) that has a set of windings (very fine wire that is wrapped around the tube) that resemble ones found in an electric motor. The windings generate a coded message that the car read. If the code is correct, then the car will allow you to start it.

There are two types of transponder chips, the one is known as the 80-bit while the other is known as the circle + (General Motors). The first is reusable, but must be unlocked with a special machine to function in a different vehicle that is compatible. The latter is more difficult since the earlier ones are often broken and then drilled through or discarded after key cases are replaced.

When your fob or key is installed in the ignition it transmits this code to a receiver within the ECU. The ECU is able to compare this code with the one that is stored in its memory, and activates both the fuel system and the ignition circuit if they are compatible. If the codes do not match, the engine won't be able to start - even if a thief tries to short-circuit the ignition circuit.
