Transponder Chips

Transponder chips can be found in head of the key on almost all new cars manufactured since 1995. They can be used to disable immobiliser systems. The head of a key that is equipped with a transponder chip may be removed to reveal a steel L-shaped key. The process of getting a replacement key fob made of a transponder chip is a multi-stage process that includes precise cutting of the replacement keys and programming the transponder chip in order to synch up with the vehicle's immobiliser system.

A transponder is a device with Non-Volatile Memory. It is comprised of a set of windings, which are very delicate wires that are twisted around a tube. They look like those in an electric motor. The windings create a coded signal for the car to read. If the code is valid, then the car will allow you to start it up.

There are two kinds of transponder chips. The one is known as the 80-bit and the second is called the circle + (General Motors). The first one is reusable, but it must be unlocked with a special machine in order to work on a different vehicle compatible with it. The second is more difficult to use due to the fact that the older ones could be damaged, broken or thrown out when key cases are changed.

Immobiliser Systems

Immobiliser systems are electronic security measures that stop thieves from starting your vehicle. It operates by sending an electronic signal from the vehicle to the key every time you attempt to start it. The electronic chip inside the key responds by sending a unique code that must match the one of the vehicle to allow it to start. If the codes don't match, your engine will stop immediately and stop the theft of your car.

Modern smart keys and fobs come with an embedded transponder that can store electronic security information in a format which can't be copied easily. When the key or fob are placed in the ignition, they send this code to the ECU. The ECU analyzes this code in comparison to the one that is stored in its memory, and then activates the fuel system and the ignition circuit if they match. If the codes do not match then the engine will not start, even when the ignition circuit is cut off by a criminal.

The replacement of the fob or key involves multiple steps that include cutting the new blade precisely and programming it so that it syncs with your car's systems. Each immobiliser system is distinct and has its own programming procedure.
