A replacement key or fob with a transponder chip is a multi-stage procedure that includes accurate cutting of the replacement keys as well as programming the transponder chip so that it can synch up 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 wrapped around tubes) which look similar to ones found in an electric motor. These windings produce a coded message that the car is able to read. If the code is correct, then the car will allow you to start it.

There are two types of transponder chips, the one is known as the 80-bit while the other is known as the circle + (General Motors). The former is reusable but needs to be unlocked by a special machine to function in a compatible vehicle. The latter one is more difficult since the earlier ones are often broken and drilled or discarded after key cases are replaced.

Immobiliser Systems

An immobiliser system is a security measure that uses electronic technology which prevents thieves from opening your vehicle. It operates by sending a signal from your vehicle to the key whenever you attempt to start it. The electronic chip inside the key responds by sending a unique code that must match the one of the vehicle in order for it to start. If the codes do not coincide, your 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 which can't be copied easily. When your fob or key is put into 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 are compatible. If the codes don't match, the engine will not start - even if an armed robber attempts to short-circuit the ignition circuit.
