Transponder Chips

Transponder chips are present in the key heads of a majority of new cars produced since 1995. They are used to disable immobiliser systems. If you've got keys with a chip, the head is covered in a plastic cover that can be pulled off to reveal an L-shaped metal key. A transponder-chip replacement key, also known as a fob is a multi-stage process. It involves cutting keys precisely and programming the chip to communicate with the vehicle immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) which contains a set of windings (very fine wire wrapped around a tube) which look similar to ones found in an electric motor. These windings generate a signal for the car to read. If the code is correct, then the car will allow you to start it.

There are two kinds of transponder chip. The one is known as the 80-bit, while the second is called the circle + (General Motors). The first is reusable, however it needs to be delocked using a specific machine in order to work on a different vehicle compatible with it. The latter type is more difficult, as the older ones are often broken or drilled through, or thrown away when key cases are replaced.

Immobiliser Systems

An immobiliser is a security measure that uses electronic technology that deters thieves from starting your vehicle. It operates by sending an electronic signal from the vehicle to your key each time you attempt to start it. The electronic chip inside your key then responds with a unique code which must match the one found in the vehicle in order to start. If the codes aren't compatible, the engine will stop immediately, preventing theft of your car.

Modern smart keys and fobs are equipped with an embedded transponder chip that stores electronic security in a format that cannot be easily duplicated. When your key or fob is put into the ignition, it transmits the code to a receiver in the ECU. The ECU examines the code against the one 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 will not start - even if someone tries to short-circuit the ignition circuit.
