A transponder-chip replacement key, also known as a fob is a process that involves multiple stages. It involves cutting keys precisely and programming the chip to communicate with the vehicle's immobiliser.
Transponders are electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire wrapped around a tube) that resemble ones found in an electric motor. The windings generate a coded message that the car can read. If the code is valid, then the car will allow you to start it.
There are two types of transponder chip, one known as the 80 bit, and the other is known as a circle + (General Motors). The former can be reused but must be delocked by a specific machine in order to work in another compatible vehicle.

Immobiliser Systems
Immobiliser systems are electronic security devices that prevent thieves from starting up your car. It works by sending a signal from your vehicle to your key when you attempt to start it.

Modern smart keys and fobs come with an embedded transponder which stores electronic security information in a format which cannot be easily copied. When your fob or key is installed in the ignition it transmits this code to a receiver inside the ECU. The ECU examines the code against the one it has stored in its memory, and it activates the fuel system and the ignition circuit if they match. If the codes do not match, the engine will not start, even in the event that the ignition circuit is damaged by a thief.
Replacing a fob or key is a multi-stage process that involves precise cutting of the new blade of the key and programming it to work with your car's immobiliser system. Each immobiliser system is unique and has its own programming procedure.
