The head of a key that has a transponder chip can be removed to reveal an L-shaped key. The process of getting a replacement key fob made with a transponder chip is a multi-stage method that includes precise cutting of replacement keys as well as programming the transponder chip to synch up with the vehicle's immobiliser.

A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire wrapped around the tube) that resemble ones in an electric motor. The windings are coded to create a signal that the car can read. If the code is correct then the car will allow you to start it.

There are two types of transponder chips, one known as the 80 bit, and the other known as a circle + (General Motors). The first can be reused, but has to be unlocked with a special machine to function on another compatible vehicle. The latter type is more difficult because the previous ones are often broken, drilled through or thrown away when key cases are replaced. They can be salvaged, however and used with a service key that doesn't require a battery in order to function.

Immobiliser Systems

An immobiliser is an electronic security feature which prevents thieves from opening your vehicle. It works by sending a signal from your vehicle to the key when you attempt to start it. The electronic chip in the key responds by sending a unique code which must match that of the vehicle to allow it to start. If the codes do not match, the engine will stop immediately, and stop theft of your car.

Modern smart keys and fobs are equipped with an embedded transponder which stores electronic security information in a format that is not easily copied. When the key or fob are inserted into the ignition, they send this code to the ECU. The ECU analyzes this code in comparison to the one in its memory, and it activates the fuel system and the ignition circuit if they match. If the codes don't match then the engine will not start, even if the ignition circuit is short-circuited by a burglar.
