Transponder Chips

More or less all new cars manufactured after 1995 have transponder chips inside the head of the key to disable the immobiliser system. If you have a key that has a chip inside it, the head has a plastic cover that can be pulled off to reveal an 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 connect with the vehicle immobiliser.

A transponder is a chip with Non-Volatile Memory. It has a set of windings which are delicate wires that are twisted around a tube. They resemble the ones in an electric motor. These windings produce a coded message that the car is able to read. If the code is correct the car will start.

There are two kinds of transponder chip, one known as the 80 bit and the other is known as a circle + (General Motors). The first one can be reused, but has to be unlocked with a special machine in order to work on a different vehicle compatible with it. The latter type is more difficult since the earlier ones are often broken and then drilled through or thrown away when key cases are replaced. They can be salvaged however and used with the service key, which does not require a battery to operate.

Immobiliser Systems

An immobiliser is a security measure that uses electronic technology that prevents thieves from starting your vehicle. It operates by sending a signal from your vehicle to the key when you attempt to start it. The electronic chip in the key responds with an individual code that must match that of the vehicle to start. If the codes don't match, the engine will shut down immediately and prevent theft of your car.

Modern smart keys and fobs contain an embedded transponder which stores electronic security information in a format which can't be copied easily. When the fob or key are placed in the ignition, they transmit this code to the ECU. The ECU compares this code with the one stored in its memory, and then activates both the fuel system and the ignition circuit if they are compatible. If the codes do not match then the engine will not start even when the ignition circuit is cut off by a criminal.

Replacing a fob or key is a multi-stage procedure that involves accurate cutting of the new key blade, and programming it to synch with the immobiliser system of your vehicle. Every immobiliser system is unique and has its own unique programming procedure.
