Transponder Chips

Transponder chips are present in the key heads of almost all new cars produced since 1995. They are used to disable immobiliser systems. If you have a key that has a chip inside it, the head has a plastic cover that is able to be pulled off to reveal an L-shaped key. The process of getting a replacement key fob made of transponder chips is a multi-stage process that includes accurate cutting of the replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser.

A transponder is an electronic device with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire wrapped around the tube) that look like the ones found in an electric motor. These windings transmit a message that the car can read. If the code is correct then the car will allow you to start it.

There are two kinds of transponder chip, the first is called the 80-bit and the other is called the circle + (General Motors).

They can be salvaged, however and then used to create a service key that does not require a battery to operate.


Immobiliser Systems

An immobiliser system is a digital security device that deters thieves from starting your vehicle. It operates by sending an electronic signal from your car to the key each time you try to start it. The chip inside the key responds by sending a unique code that must match the one of the vehicle in order for it to start. If the codes do not match, the engine will shut down immediately, preventing theft of your vehicle.

Modern smart keys and fobs have embedded transponder chips that stores electronic security in a format that can't be easily duplicated. When the fob or key are placed in the ignition, they send this code to the ECU. The ECU compares this code with the one stored in its memory, and it activates both the fuel system as well as the ignition circuit if they are compatible. If the codes don't match and the engine does not start even if the ignition circuit is damaged by a thief.
