A transponder-chip replacement key, also known as a fob is a process that involves multiple stages. It involves cutting the keys precisely and programming the chip to communicate with the vehicle's immobiliser.

Transponders are electronic chip with Non-Volatile Memory (NVM) that contains a set of windings (very fine wire that is wrapped around a tube) that resemble ones in an electric motor. These windings create a coded message that the car is able to read. If the code is valid, then the car will allow you to start it up.
