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

Transponders are electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire that is wrapped around a tube) that resemble ones found in an electric motor. The windings are coded to create a signal for the car to read. If the code is correct, then the car will allow you to start it.

There are two types of transponder chips. One known as the 80 bit and the other is known as a circle + (General Motors). The first type is reusable, but must be delocked using a specific machine to function on another compatible vehicle.
