The head of a key that contains a transponder chip is able to be removed to reveal an L-shaped key. A transponder-chip replacement key or fob is a multi-stage process. It involves cutting the keys accurately and programming the chip to connect with the vehicle immobiliser.
Transponders are electronic chip equipped with Non-Volatile memory (NVM) which contains a set of windings (very fine wire that is wrapped around a tube) which look similar to ones found in an electric motor. These windings produce a coded message that the car is able to read. If the code is correct it will allow the car to start.
There are two types of transponder chip, the first is called the 80-bit and the other is called the circle + (General Motors). The first is reusable, but must be removed using a special machine to function in a different vehicle that is compatible.

Modern smart keys and fobs come with an embedded transponder, which stores electronic security information in a format which cannot be easily copied. When the key or fob are inserted in the ignition, they send this code to the ECU. The ECU is then able to compare it with the code in its memory, and activates the ignition and fuel system circuit if they coincide. If the codes do not match and the engine does not start, even when the ignition circuit has been short-circuited by a thief.
