The head of a key that contains a transponder chip is able to be removed to reveal a steel L-shaped key. The process of getting a replacement key fob that is made using transponder chips is a multi-stage process which includes accurate cutting of the replacement keys and programming of the transponder chip in order to synch up with the vehicle's immobiliser system.

Transponders are chips with Non-Volatile Memory. It has a set of windings that 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 is able to read. If the code is valid, then the car will allow you to start it up.

When your fob or key is put into the ignition, it transmits the code to a receiver in the ECU. The ECU analyzes this code in comparison to the one it has stored in its memory, and then activates both the fuel system as well as the ignition circuit if they are compatible. If the codes do not match, the engine will not start - even if a burglar tries to short-circuit the ignition circuit.
