It involves cutting the keys precisely and programming the chip to make it sync with the vehicle's immobiliser.

A transponder is a device with Non-Volatile Memory. It is comprised of a set of windings, which are fine wires that are wrapped around a tube. They look like those 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 up.

There are two kinds of transponder chips. One is known as the 80 bit, and the other referred to as a circle + (General Motors). The first type can be reused, but has to be delocked using a specific machine to function on a different vehicle compatible with it.

Immobiliser Systems

An immobiliser system is a digital security device which prevents thieves from opening your vehicle. It works by sending a signal from the vehicle to your key when you attempt to start it. The chip inside the key responds by transmitting a unique code that must match the one of the vehicle to allow it to start. If the codes do not match, your engine will immediately shut down to prevent theft.

Modern smart keys and fobs feature embedded transponder chips that stores security information in a format that cannot be easily duplicated. When the key or fob is inserted into the ignition, they transmit this code to the ECU. The ECU compares this code with the one it has stored in its memory, and activates both the fuel system and the ignition circuit if they match. If the codes don't match, your engine won't start - even if someone tries to short-circuit the ignition circuit.
