A replacement key or fob made with a transponder chip is a multi-stage process which includes precise cutting of key replacements and programming the transponder chip to synch up with the vehicle's immobiliser.

Transponders are electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire wrapped around tubes) that look like the ones found in an electric motor. These windings generate a signal that the car can read. If the code is correct, then the car will allow you to start it.

There are two kinds of transponder chip, one known as the 80 bit, and the other known as a circle + (General Motors).

Immobiliser Systems

An immobiliser system is an electronic security measure that prevents thieves from starting your vehicle. It works by sending a signal from your vehicle to the key whenever you attempt to start it.

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 placed in the ignition, they transmit this code to the ECU. The ECU compares this code with the one it has stored in its memory, and it activates both the fuel system and the ignition circuit if they are compatible. If the codes do not match, the engine will not start, even if a burglar tries to short-circuit the ignition circuit.
