The head of a key which includes a transponder chips can be removed to reveal a steel L-shaped key. Making a replacement key, or fob made of transponder chips is a multi-stage method that includes precise cutting of key replacements and programming the transponder chip so that it can synch up with the vehicle's immobiliser system.

Transponders are chips with Non-Volatile Memory. It has a set windings that are fine wires coiled around the tube. They look like the ones in an electric motor. These windings form a coded signal for the car to read. If the code is correct the car will start.
