Transponder Chips

Transponder chips can be found in key heads of almost all new vehicles manufactured after 1995. They can be used to disarm immobiliser systems. If you've got a car key that has a chip inside it, the head has a plastic cover that can be pulled off to reveal an L-shaped key. A transponder-chip replacement key or fob is a process that involves multiple stages. It involves cutting the keys precisely and programming the chip to make it sync with the vehicle's immobiliser.

A transponder is an electronic device with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire wrapped around a tube) that resemble ones in an electric motor. The windings are coded to create a signal that the car can read. If the code is correct it will allow the car to start.

There are two kinds of transponder chip, one known as the 80 bit, and the other one is called a circle + (General Motors). The first type is reusable, however it needs to be removed using a special machine to function on another compatible vehicle. The latter is more difficult since the earlier keys are usually broken and then drilled through or thrown away when key cases are replaced.

Immobiliser Systems

Immobiliser systems are electronic security measures that stop thieves from starting your vehicle. It works by sending an electronic signal from your car to the key whenever you try to start it. The electronic chip in the key responds by sending a unique code which must match that of the vehicle in order for it to start. If the codes do not match, the engine will shut down immediately and stop the theft of your vehicle.

Modern smart keys and fobs are equipped with an embedded transponder chip that stores security information in a format that can't be duplicated. When the key or fob are inserted in the ignition, they send this code to the ECU. The ECU then compares it to the code stored in its memory and activates the fuel system and ignition circuit if they match. If the codes don't match, the engine won't start - even if someone tries to short-circuit the ignition circuit.

The process of replacing a key or fob involves an entire process that involves cutting the new blade with precision and programming it to ensure that it syncs with your car's systems.
