The head of a key that contains a transponder chip is able to be removed to reveal a metal L-shaped key. A transponder-chip replacement keys or fob is a multi-stage process. It involves cutting the keys precisely and programming the chip to connect with the vehicle's immobiliser.
A transponder is a type of chip with Non-Volatile Memory. It has a set windings that are fine wires wrapped around the tube. They look like the ones in an electric motor. These windings create a coded message that the car read. If the code is correct, the car will start.
There are two types of transponder chips. One is known as the 80 bit, and the other is known as a circle + (General Motors). The first one is reusable, but must be removed using a special machine in order to work on a vehicle that is compatible with the. The latter one is more difficult because the previous keys are usually damaged and drilled or thrown away when key cases are replaced.

Immobiliser Systems
An immobiliser system is an electronic security feature that deters thieves from starting your car. It works by sending an electronic signal from your car to the key every time you attempt to start it. The chip inside the key responds by sending a unique code which must match the one of the vehicle in order for it to start. If the codes do not match, your engine will immediately shut down to prevent theft.
Modern smart keys and fobs are equipped with an embedded transponder which stores electronic security information in a format which can't be copied easily. When your fob or key is inserted into the ignition, it transmits the code to a device within the ECU. The ECU then compares it to the code in its memory. It then activates the ignition and fuel system circuit if the two match. If the codes do not match, the engine will not start, even if the ignition circuit is short-circuited by a thief.
