Transponder Chips

Transponder chips are found in the key heads of almost all new cars produced since 1995. They are used to disable immobiliser systems. If you've got keys that has a chip inside it, the head has a plastic cover that is able to be pulled off to reveal an L-shaped key. A replacement key or fob with a transponder chip is a multi-stage process which includes precise cutting of replacement keys and programming the transponder chip to link up with the vehicle's immobiliser.

Transponders are electronic device with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire coiled around tubes) which look similar to ones found in an electric motor. The windings generate a coded message that the car read. If the code is correct the car will begin to move.

There are two kinds of transponder chip. The first is called the 80-bit and the other is known as the circle + (General Motors). The first one is reusable, but must be delocked using a specific machine in order to work in a different vehicle that is compatible. The latter is more difficult, as the older ones are often broken or drilled through, or discarded after key cases are replaced. However they can be used with a service-key that does not require batteries.

Immobiliser Systems

Immobiliser systems are electronic security devices that prevent thieves from starting your car. It works by sending an electronic signal from your car to the key whenever you attempt to start it. The electronic chip inside your key responds by sending an individual code that must match the one found in the vehicle in order to start. If the codes do not match, the engine will shut down immediately and stop the theft of your car.

Modern smart keys and fobs have an embedded transponder which stores electronic security information in a format which cannot be easily copied. When the key or fob are inserted in the ignition, they send this code to the ECU. The ECU examines the code against the one stored in its memory, and it activates both the fuel system as well as the ignition circuit if they match. If the codes don't match, the engine will not start - even if someone tries to short-circuit the ignition circuit.

Replacing a fob or key is a multi-stage process which involves precise cutting the new key blade and programming it to work with the immobiliser system of your vehicle. Each immobiliser is unique and has its own programming procedure. We utilize Ross-Tech software to ensure that your replacement key is programmed correctly to ensure maximum performance and security.
