The head of a key that includes a transponder chips can be removed to reveal a steel L-shaped key. A transponder-chip replacement key or fob is a multi-stage process. It involves cutting keys precisely and programming the chip to connect with the vehicle immobiliser.

A transponder is a chip with Non-Volatile Memory. It has a set windings, which are very fine wires coiled around the tube. They look like those in an electric motor. The windings create a coded signal for the car to read. If the code is correct, the car will start.

There are two kinds of transponder chips, the first is called the 80-bit, while the second is called the circle + (General Motors). The former type is reusable but it needs to be unlocked by a machine that is specially designed to be used in a compatible vehicle. The latter is a bit more difficult as the old ones are often broken and then drilled through or discarded after key cases are replaced.

Immobiliser Systems

Immobiliser systems are electronic security devices that prevent thieves from starting up your vehicle. It operates by sending an electronic signal from the car to the key every time you attempt to start it. The electronic chip inside the key responds by sending a unique code which must match that of the vehicle to allow it to start. If the codes don't coincide, your engine will stop immediately to prevent theft.

Modern smart keys and fobs have an embedded transponder that can store electronic security information in a format which cannot be easily copied. When your key or fob is put into the ignition, it transmits this code to a receiver inside the ECU. The ECU then compares it to the code that is stored in its memory, and activates the fuel system and ignition circuit if the two coincide. If the codes do not match, the engine will not start, even if a burglar tries to short-circuit the ignition circuit.
