The head of a key that includes a transponder chips can be removed to reveal a steel L-shaped key. Making a replacement key, or fob made with transponder chips is a multi-stage process which includes precise cutting of the replacement keys and programming the transponder chip 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 wrapped around a tube) that resemble ones in an electric motor. These windings produce a coded message that the car will read. If the code is correct, the car will start.

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