Transponder Chips

More or less all new cars manufactured after 1995 have transponder chips inside the key head that allow it to deactivate the immobiliser system. The head of a key which contains a transponder chip is able to be removed to reveal an L-shaped key. A transponder chip replacement key or fob is a process that involves multiple stages. It involves cutting keys precisely and programming the chip to sync up with the vehicle's immobiliser.

Transponders are electronic chip that has Non-Volatile Memory (NVM) that contains a set of windings (very fine wire coiled around a tube) that look like the ones found in an electric motor. These windings create a coded message that the car can read. If the code is valid, then the car will allow you to start it.

There are two kinds of transponder chips. The first is called the 80-bit and the other is called the circle + (General Motors). The first type is reusable, however it needs to be unlocked with a special machine in order to work on another compatible vehicle. The latter is a bit more difficult, as the older keys are often damaged and then drilled through or discarded after key cases are replaced.

Immobiliser Systems

Immobiliser systems are electronic security devices that deter thieves from starting your car. It works by sending an electronic signal from the vehicle to the key every time you attempt to start it. The electronic chip inside the key responds with a unique code that must match the one found in the vehicle to start. If the codes do not match, the engine will immediately shut down to prevent theft.

Modern smart keys and fobs have an embedded transponder, which stores electronic security information in a format that cannot be easily copied. When your fob or key is installed in the ignition it transmits this code to a receiver inside the ECU. The ECU examines the code against the one stored in its memory and activates the fuel system and the ignition circuit if they match. If the codes don't match the engine won't start, even in the event that the ignition circuit is cut off by a criminal.
