It involves cutting the keys precisely and programming the chip to communicate with the vehicle's immobiliser.

A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that has a set of windings (very fine wire coiled around the tube) that look like the ones found in an electric motor. These windings generate a signal for the car to read. If the code is correct, the car will start.

There are two kinds of transponder chips. One called the 80 bit and the other referred to as a circle + (General Motors). The first type is reusable, however it needs to be removed using a special machine in order to work on a different vehicle compatible with it. The latter type is more difficult since the earlier keys are often damaged or drilled through, or thrown away when key cases are replaced.

Immobiliser Systems

An immobiliser system is a security measure that uses electronic technology that stops thieves from starting your car.

The electronic chip in your key responds by sending a unique code that must match that of the vehicle in order to start. If the codes do not match, the engine will stop immediately to prevent theft.

Modern smart keys and fobs are equipped with an embedded transponder, which stores electronic security information in a format that cannot be easily copied. When your fob or key is inserted into the ignition, it transmits this code to a receiver in the ECU. The ECU examines the code against the one it has stored in its memory, and then activates both the fuel system as well as the ignition circuit if they match. If the codes do not match, the engine will not start - even if a burglar tries to short-circuit the ignition circuit.
