Making a replacement key, or fob made of transponder chips is a multi-stage method that involves precise cutting of replacement keys and programming the transponder chip to synch up with the vehicle's immobiliser.

A transponder is an electronic chip equipped with Non-Volatile memory (NVM) which contains a set of windings (very fine wire twisted around a tube) which look similar to ones in an electric motor. The windings create a coded 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 known as the 80 bit and the other known as a circle + (General Motors). The first kind is reusable, but it must be unlocked with a special machine to function in a different vehicle that is compatible. The second is more difficult to use since the old ones can be broken, drilled or toss out when keycases are changed. However they can be used with a service-key which doesn't require a battery.

Immobiliser Systems

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