The head of a key which has a transponder chip can be removed to reveal a metallic L-shaped key. A transponder-chip replacement keys or fob is a multi-stage process. It involves cutting the keys accurately and programming the chip to make it sync with the vehicle's immobiliser.

Transponders are chips that has Non-Volatile Memory. It has a set of 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 read. If the code is correct, the car will start.

There are two kinds of transponder chips, the first is called the 80-bit, while the second is known as the circle + (General Motors). The first is reusable but it needs to be unlocked with a special device 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. However they can be used with a service-key which does not require a battery.

Immobiliser Systems

Immobiliser systems are electronic security devices that stop thieves from starting up your vehicle. It operates by sending an electronic signal from the car to the key every time you attempt to start it. The electronic chip in 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 don't match, the engine will shut down immediately and stop the theft of your vehicle.

Modern smart keys and fobs come with an embedded transponder chip that stores security information in a format that can't be duplicated. When your fob or key is placed in the ignition, it transmits the code to a receiver within the ECU. The ECU examines the code against the one it has stored in its memory and activates both the fuel system and 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 short-circuited by a burglar.
