A replacement key or fob with a transponder chip is a multi-stage procedure that includes precise cutting of the replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser.

Transponders are chips with Non-Volatile Memory. It has a set windings, which are fine wires wrapped around a tube. They resemble the ones in an electric motor. These windings produce a coded message that the car is able to read. If the code is correct, the car will start.

There are two types of transponder chips, one known as the 80 bit, and the other referred to as a circle + (General Motors). The former is reusable but must be delocked by a specific machine in order to work in another compatible vehicle.

Immobiliser Systems

An immobiliser system is a security measure that uses electronic technology which prevents thieves from opening your vehicle. It works by sending an electronic signal from the car to the key every time you attempt to start it. The chip inside the key responds with an individual code that must match that of the vehicle in order to start. If the codes aren't compatible, the engine will stop immediately, preventing theft of your car.

Modern smart keys and fobs come with an embedded transponder chip that stores electronic security in a format that cannot be easily duplicated. When the fob or key is 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 match. If the codes do not match the engine won't start even if the ignition circuit is short-circuited by a thief.
