Transponder Chips

Transponder chips are found in the key heads of almost all new cars built since 1995. They are used to disable immobiliser systems. The head of a key which has a transponder chip can be removed to reveal a metallic L-shaped key. A replacement key or fob made with a transponder chip is a multi-stage method that includes accurate cutting of the replacement keys and programming of the transponder chip to synch up with the vehicle’s immobiliser system.

Transponders are electronic device with Non-Volatile Memory (NVM) that houses a set of windings (very fine wire that is wrapped around tubes) which look similar to ones 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, one known as the 80 bit, and the other one is called a circle + (General Motors). The first kind is reusable, however it needs to be removed using a special machine in order to work in a different vehicle that is compatible. The second type is more difficult to use due to the fact that the old ones can be damaged, broken or removed when key cases are changed.

Immobiliser Systems

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

Modern smart keys and fobs come with embedded transponder chips that stores electronic security in a format that cannot be easily duplicated. When your fob or key is placed in the ignition, it transmits this code to a receiver inside the ECU. The ECU examines the code against the one stored in its memory, and it activates the fuel system and the ignition circuit if they match. If the codes don’t match, the engine won’t start – even if a thief tries to short-circuit the ignition circuit.

Replacing a fob or key is a multi-stage procedure that requires precise cutting of the new blade of the key and programming it to synch with your car’s immobiliser system. There are many different immobiliser systems used in different years and models and each has its own unique programming procedure.
