Transponder Chips

Transponder chips are present in the key heads of a majority of new cars manufactured since 1995. They are used to disarm immobiliser systems. The head of a key that includes a transponder chips can be removed to reveal a metal L-shaped key. A replacement key or fob with transponder chips is a multi-stage procedure that involves precise cutting of replacement keys and programming of the transponder chip so that it can synch up with the vehicle's immobiliser system.

Transponders are electronic device with Non-Volatile Memory (NVM) that contains a set of windings (very fine wire coiled around the tube) which look similar to ones in an electric motor. These windings transmit a message that the car will read. If the code is valid, then the car will allow you to start it up.

There are two types of transponder chip. The first is called the 80-bit, while the second is known as the circle + (General Motors). The first is reusable but must be delocked by a machine that is specially designed to work in another compatible vehicle. The second is more difficult to use as the old keys can be damaged, drilled or thrown out when key cases are changed.

When the key or fob are placed 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 are compatible. If the codes do not match then the engine will not start even when the ignition circuit has been damaged by a thief.
