Transponder Chips

Nearly all new cars since 1995 have transponder chips embedded in the key head to disarm the immobiliser system. If you've got a car key with a chip inside, the head has a plastic cover that can be pulled off to reveal an L-shaped key. A transponder-chip replacement keys or fob is a multistage process. It involves cutting the keys accurately and programming the chip to sync up with the vehicle immobiliser.

Transponders are electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire wrapped around the tube) that resemble ones found in an electric motor. These windings generate a signal 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 chips. One known as the 80 bit and the other one is called a circle + (General Motors). The first is reusable, but it must be delocked using a specific machine to function on a different vehicle compatible with it. The latter is a bit more difficult since the earlier keys are usually broken, drilled through or discarded when key cases are replaced. However they can be used with a key-service that does not require a battery.

Immobiliser Systems

Immobiliser systems are electronic security devices which prevent thieves from starting up your vehicle.

Modern smart keys and fobs have embedded transponder chips that stores electronic security in a format that cannot be easily duplicated. When your key or fob is put into the ignition, it transmits the code to a receiver within the ECU. The ECU will then check it against the code stored in its memory and activates the ignition system and fuel circuit if the two coincide. If the codes do not match, the engine will not start, even if someone tries to short-circuit the ignition circuit.

The replacement of the fob or key requires multiple steps that include cutting the new blade with precision and programming it so that it syncs with your car's systems. There are many different immobilisers used in different years and models and each has its own distinct programming process.
