Transponder Chips
Transponder chips are in the key heads of a majority of new cars produced since 1995. They can be used to disarm immobiliser systems. If you've got keys that has a chip inside it, the head is covered with a plastic cover that can be taken off to reveal an L-shaped key. Making a replacement key, or fob with a transponder chip is a multi-stage method that includes accurate cutting of the replacement keys and programming the transponder chip in order to synch up with the vehicle's immobiliser.
Transponders are chips that has Non-Volatile Memory. It has a set windings which are fine wires coiled around the tube. They resemble the ones in an electric motor. These windings produce a coded message that the car will read. If the code is correct the car will begin to move.
There are two types of transponder chips, the one is known as the 80-bit and the second is known as the circle + (General Motors). The first is reusable but it needs to be unlocked by a specific machine in order to function in a different compatible vehicle. The latter is a bit more difficult, as the older keys are often damaged and then drilled through or discarded after key cases are replaced.

Immobiliser Systems
An immobiliser is a security measure that uses electronic technology that stops thieves from starting your car. It operates by sending an electronic signal from the vehicle to your key each time you attempt to start it. The electronic chip in the key responds by sending a unique number of codes that must match that of the vehicle to allow it to start. If the codes do not match, the engine will stop immediately and stop the theft of your vehicle.
Modern smart keys and fobs contain an embedded transponder that can store electronic security information in a format which cannot be easily copied. When your fob or key is placed in the ignition, it transmits the code to a receiver inside the ECU. The ECU examines the code against the one it has stored in its memory and activates both the fuel system as well as the ignition circuit if they are compatible. If the codes do not match and the engine does not start even when the ignition circuit is short-circuited by a thief.
