A transponder-chip replacement key, also known as a fob is a multi-stage process. It involves cutting the keys precisely and programming the chip to connect with the vehicle immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that has a set of windings (very fine wire twisted around the tube) that resemble ones found in an electric motor. The windings generate a coded message that the car is able to read. If the code is correct it will allow the car to start.

There are two types of transponder chips. One is called the 80 bit and the other referred to as a circle + (General Motors).

Immobiliser Systems

An immobiliser is an electronic security measure that prevents thieves from starting your vehicle. It works by sending an electronic signal from the vehicle to the key each time you try to start it.

Modern smart keys and fobs come with an embedded transponder chip that stores security information in a format that cannot be easily duplicated. When your fob or key is put into the ignition, it transmits this code to a receiver within the ECU. The ECU examines the code against the one stored in its memory and activates the fuel system and the ignition circuit if they match. If the codes do not match then the engine will not start even in the event that the ignition circuit is cut off by a criminal.
