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

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

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