It involves cutting keys precisely and programming the chip to connect with the vehicle immobiliser.
A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that contains a set of windings (very fine wire coiled around a tube) that resemble ones in an electric motor. These windings create a coded message that the car will read. If the code is correct the car will start.
There are two types of transponder chips, one called the 80 bit and the other is known as a circle + (General Motors).

Immobiliser Systems
An immobiliser is a security measure that uses electronic technology which prevents thieves from opening your vehicle. It works by sending an electronic signal from the car to your key each time you try to start it. The chip inside your key responds with an unique code that must match that of the vehicle in order to start. If the codes don't match, your engine will shut down immediately to prevent theft.
Modern smart keys and fobs are equipped with an embedded transponder that stores electronic security information in a format that cannot be easily copied. When the key or fob are inserted into the ignition, they send this code to the ECU. The ECU will then check it against the code in its memory. It then activates the ignition system and fuel circuit if they coincide. If the codes don't match the engine won't start, even if the ignition circuit is short-circuited by a burglar.
