The head of a key that is equipped with a transponder chip may be removed to reveal an L-shaped key. Having a replacement key or fob made of transponder chips is a multi-stage process which includes accurate cutting of the key replacements and programming the transponder chip in order to synch up with the vehicle's immobiliser.

Transponders are chips that has Non-Volatile Memory. It has a set windings, which are fine wires wrapped around a tube. They look like the ones in an electric motor. The windings create a coded signal that the car can read. If the code is correct the car will begin to move.

There are two types of transponder chips. The one is known as the 80-bit while the other is called the circle + (General Motors).
