Transponder Chips

Transponder chips are found in the key heads of a majority of new cars manufactured since 1995. They are used to disarm immobiliser systems. If you have a key that has a chip inside it, the head has a plastic cover that is able to be pulled off to reveal an L-shaped metal key. Having a replacement key or fob with a transponder chip is a multi-stage method that includes precise cutting of the key replacements and programming the transponder chip to synch up with the vehicle's immobiliser.

Transponders are electronic device with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire wrapped around tubes) which look similar to ones found in an electric motor. The windings create a coded 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, one called the 80 bit and the other is known as a circle + (General Motors). The former type is reusable but must be delocked by a special machine to work in another compatible vehicle. The second one is more difficult to use because the older ones could be broken, drilled or toss out when keycases are changed. They can be salvaged however and used with the service key, which does not require a battery to operate.

Immobiliser Systems

An immobiliser is an electronic security measure that deters thieves from starting your vehicle. It works by sending an electronic signal from your car to your key each time you attempt to start it. The electronic chip inside the key responds by transmitting a unique code that must match the one of the vehicle to allow it to start. If the codes aren't compatible, the engine will shut down immediately, preventing theft of your vehicle.

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 fob or key is inserted into the ignition, it transmits the code to a device within the ECU. The ECU will then check it against the code stored in its memory, and activates the ignition and fuel system circuit if the two coincide. If the codes do not match, the engine won't start - even if a burglar tries to short-circuit the ignition circuit.

Replacing a fob or key is a multi-stage process that requires precise cutting of the new blade of the key and programming it to communicate with the immobiliser system of your vehicle. Every immobiliser system is unique and has its own programming procedure. We employ Ross-Tech to ensure that the replacement key is programmed correctly.
