It involves cutting keys precisely and programming the chip to connect with the vehicle immobiliser.

A transponder is a device that has Non-Volatile Memory. It is comprised of a set of windings, which are very fine wires that are wrapped around a 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 then the car will allow you to start it.
