Transponder Chips

Transponder chips are in the head of the key on almost all new cars built since 1995. They can be used to disarm immobiliser systems. If you've got a key with a chip inside, the head comes with a cover that can be pulled off to reveal an L-shaped key. A transponder-chip replacement key or fob is a multi-stage process. It involves cutting the keys precisely and programming the chip to connect with the vehicle's immobiliser.

Transponders are electronic chip with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire coiled around the tube) that resemble ones in an electric motor. These windings produce a coded message that the car is able to read. If the code is correct then the car will allow you to start it up.

There are two types of transponder chip, the one is known as the 80-bit and the other is called the circle + (General Motors). The first one can be reused, but has to be unlocked using a special machine in order to work on a vehicle that is compatible with the. The latter one is more difficult, as the older keys are usually damaged, drilled through or discarded after key cases are replaced.

When your key or fob is placed in the ignition, it transmits the code to a receiver in the ECU. The ECU compares this code with the one that is stored in its memory, and it activates the fuel system and the ignition circuit if they are compatible. If the codes don't match, the engine will not start, even if an armed robber attempts to short-circuit the ignition circuit.
