Transponder Chips
Transponder chips are present in the key heads of almost all new cars produced since 1995. They are used to disarm immobiliser systems. The head of a key that contains a transponder chip is able to be removed to reveal a steel L-shaped key. A transponder-chip replacement keys or fob is a multi-stage procedure. It involves cutting the keys precisely and programming the chip to connect with the vehicle immobiliser.
A transponder is an electronic device with Non-Volatile Memory (NVM) that contains a set of windings (very fine wire wrapped around tubes) that resemble ones found in an electric motor. The windings create a coded 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 chip. The first is called the 80-bit and the second is called the circle + (General Motors). The former is reusable but needs to be unlocked with a special device to function in a compatible vehicle. The latter is more difficult as the old ones are often broken, drilled through or thrown away when key cases are replaced. However they can be used with a service-key that doesn’t require a battery.
Immobiliser Systems
An immobiliser is an electronic security measure that deters thieves from starting your car. It works by sending a signal from the vehicle to your key when you attempt to start it. The chip inside the key responds by transmitting a unique code that must match the one of the vehicle to allow it to start. If the codes aren’t compatible, the engine will shut down immediately and prevent theft of your vehicle.
Modern smart keys and fobs feature an embedded transponder chip that stores electronic security in a format that cannot be easily duplicated. When the key or fob are placed in the ignition, they send this code to the ECU. The ECU compares this code with the one it has stored in its memory, and activates the fuel system and the ignition circuit if they are compatible. If the codes don’t match, the engine won’t be able to start – even if a burglar tries to short-circuit the ignition circuit.
The replacement of a key or fob involves an entire process that involves cutting the new key blade accurately and programming it so that it can be synced with the car’s system. There are a variety of immobilisers that are available in various models and years and each needs its own unique programming procedure.
