Certain models require that the transponder chip in the key be reprogrammed to function with the vehicle's immobiliser system.

Transponder chips are present in the keys of nearly all new cars produced since 1995. They can be used to disable immobiliser systems. The head of a key which has a transponder chip can be removed to reveal a steel L-shaped key. Making a replacement key, or fob with transponder chips is a multi-stage procedure that involves precise cutting of replacement keys as well as programming the transponder chip in order to synch up with the vehicle's immobiliser.

Transponders are electronic chip with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire twisted around the tube) that resemble ones in an electric motor. These windings produce a coded message that the car is able to read. If the code is valid, then the car will allow you to start it up.

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