A transponder-chip replacement key, also known as a fob is a multi-stage procedure. It involves cutting the keys with precision and programming the chip to sync up with the vehicle immobiliser.

A transponder is an electronic device with Non-Volatile Memory (NVM) that has a set of windings (very fine wire that is wrapped around tubes) which look similar to ones in an electric motor. These windings transmit a message that the car is able to read. If the code is correct the car will begin to move.

There are two types of transponder chips. One is called the 80 bit and the other known as a circle + (General Motors). The first is reusable, but it must be delocked using a specific machine in order to work on another compatible vehicle. The latter is more difficult because the previous keys are usually damaged and drilled or discarded when key cases are replaced. However, they can be used with a service-key that doesn't require a battery.

Immobiliser Systems

An immobiliser is a security measure that uses electronic technology that deters thieves from starting your car. It operates by sending an electronic signal from the vehicle to the key each time you try to start it. The electronic chip in the key responds by sending a unique code that must match that of the vehicle in order for it to start. If the codes don't match, the engine will shut down immediately, and stop theft of your car.

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

The process of replacing the fob or key requires a multi-stage procedure that includes cutting the new blade accurately and programming it to ensure that it syncs with your car's system. Each immobiliser system is unique and has its own unique programming procedure.
