The head of a key which contains a transponder chip is able to be removed to reveal a steel L-shaped key. A transponder-chip replacement key, also known as a fob is a process that involves multiple stages. It involves cutting keys precisely and programming the chip to communicate with the vehicle immobiliser.

Transponders are chips with Non-Volatile Memory. It has a set of windings, which are fine wires coiled around a tube. They look similar to those in an electric motor. These windings produce a coded message that the car read. If the code is valid, then the car will allow you to start it.

Immobiliser Systems

An immobiliser system is a security measure that uses electronic technology that prevents thieves from starting your vehicle.

The electronic chip inside the key responds by sending a unique code which must match the one of the vehicle to allow it to start. If the codes don't coincide, your engine will shut down immediately to stop theft.

Modern smart keys and fobs contain an embedded transponder, which stores electronic security information in a format that is not easily copied. When your fob or key is put into the ignition, it transmits the code to a device within the ECU. The ECU analyzes this code in comparison to the one that is stored in its memory and activates both the fuel system as well as the ignition circuit if they match. If the codes don't match, the engine won't start - even if someone tries to short-circuit the ignition circuit.
