If you've got a key with a chip inside, the head comes with a cover that is able to be pulled off to reveal an L-shaped metal key. A transponder-chip replacement keys or fob is a process that involves multiple stages. It involves cutting the keys accurately and programming the chip to make it sync with the vehicle's immobiliser.

Transponders are chips with Non-Volatile Memory. It has a set windings, which are very fine wires coiled around the tube. They resemble the ones in an electric motor. The windings are coded to create a signal for the car to 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 known as a circle + (General Motors). The first is reusable, however it needs to be delocked using a specific machine in order to work in a different vehicle that is compatible. The latter one is more difficult since the earlier keys are often damaged and drilled or thrown away when key cases are replaced.

Immobiliser Systems

Immobiliser systems are electronic security measures that deter thieves from starting up your vehicle. It operates by sending an electronic signal from the vehicle to the key every time you attempt to start it. The electronic chip in the key responds by transmitting a unique code that must match the one of the vehicle in order for it to start. If the codes do not match, your engine will stop immediately to stop theft.

Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format which is not easily copied. When the key or fob are inserted into the ignition, they transmit this code to the ECU. The ECU will then check it against the code in its memory. It then activates the ignition and fuel system circuit if they coincide. If the codes do not match, your engine won't start - even if someone tries to short-circuit the ignition circuit.
