Transponder chips are in the head of the key on almost all new cars built since 1995. They are used to disarm immobiliser systems. 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 method that includes accurate cutting of the replacement keys as well as programming the transponder chip to synch up with the vehicle's immobiliser system.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire that is wrapped around the tube) that look like the ones found in an electric motor. These windings generate a signal that the car can read. If the code is valid, then the car will allow you to start it up.

There are two kinds of transponder chips, one known as the 80 bit, and the other referred to as a circle + (General Motors). The first one is reusable, however it needs to be delocked using a specific machine to function in a different vehicle that is compatible. The latter type is more difficult because the previous keys are often damaged or drilled through, or thrown away when key cases are replaced. They are able to be salvaged however and used with the service key, which doesn't require batteries to function.

Immobiliser Systems

Immobiliser systems are electronic security devices that prevent thieves from starting up your vehicle.

The chip inside your key then responds with a unique code which must match the one in the vehicle in order to start. If the codes do not match, your engine will stop immediately to prevent theft.

Modern smart keys and fobs are equipped with an embedded transponder that stores electronic security information in a format which cannot be easily copied. When the key or fob are inserted into the ignition, they send this code to the ECU. The ECU is then able to compare it with the code stored in its memory. It then activates the ignition system and fuel circuit if the two coincide. If the codes do not match, your engine won't start - even if a thief tries to short-circuit the ignition circuit.
