Making a replacement key, or fob that is made using a transponder chip is a multi-stage process that includes precise cutting of key replacements and programming the transponder chip in order to synch up with the vehicle's immobiliser.

A transponder is a type of chip with Non-Volatile Memory. It is comprised of a set of windings, which are delicate wires that are twisted around the tube. They look like the ones in an electric motor. The windings create a coded signal that the car can read. If the code is correct, the car will start.

There are two kinds of transponder chips. The one is known as the 80-bit and the other is called the circle + (General Motors). The former can be reused but needs to be unlocked by a specific machine in order to function in a different compatible vehicle.

An immobiliser system is an electronic security feature that stops thieves from starting your vehicle. It operates by sending a signal from your car to the key when you attempt to start it.

Modern smart keys and fobs contain an embedded transponder which stores electronic security information in a format that is not easily copied. When the key or fob are inserted in the ignition, they send this code to the ECU. The ECU analyzes this code in comparison to the one stored in its memory and activates both the fuel system as well as the ignition circuit if they match. If the codes do not match, your engine will not start, even if someone tries to short-circuit the ignition circuit.
