The head of a key that 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 procedure that involves precise cutting of replacement keys and programming of the transponder chip so that it can synch up with the vehicle's immobiliser.

A transponder is a device with Non-Volatile Memory. It is comprised of a set of windings which are fine wires coiled around a tube. They look similar to those in an electric motor. These windings produce a coded message that the car is able to read. If the code is correct then the car will allow you to start it up.

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