Transponder Chips

More or less all new cars since 1995 have transponder chips in the key head to disable the immobiliser system. The head of a key which is equipped with a transponder chip may be removed to reveal a steel L-shaped key. A transponder-chip replacement key, also known as a fob is a multi-stage process. It involves cutting the keys with precision and programming the chip to communicate with the vehicle immobiliser.

A transponder is a device that has Non-Volatile Memory. It has a set of windings, which are very fine wires wrapped around the tube. They look like the ones in an electric motor. These windings create a coded message that the car read. If the code is correct it will allow the car to start.

There are two types of transponder chips. One known as the 80 bit, and the other referred to as a circle + (General Motors). The first kind is reusable, but it must be delocked using a specific machine in order to work on a different vehicle compatible with it. The second one 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

An immobiliser is a digital security device that deters thieves from starting your vehicle. It operates by sending a signal from your vehicle to your key when you attempt to start it. The electronic chip in your key responds by sending a unique code that must match the one found in the vehicle in order to start. If the codes do not match, the engine will shut down immediately and stop the theft of your car.

Modern smart keys and fobs are equipped with an embedded transponder that stores electronic security information in a format that cannot be easily copied. When the key or fob are inserted in the ignition, they transmit 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 the engine won't start, even if the ignition circuit is short-circuited by a thief.

Replacing a key or fob is a multi-stage process that involves accurate cutting of the new blade for the key and programming it to synch with your car's immobiliser system. There are many different immobilisers used in different models and years and each needs an individual programming procedure.
