There are two kinds of transponder chips, the first is called the 80-bit and the other is known as the circle + (General Motors). The first kind is reusable, however it needs to be unlocked using a special machine in order to work on another compatible vehicle.

Immobiliser Systems

An immobiliser system is an electronic security measure that prevents thieves from starting your car. It works by sending an electronic signal from your car to the key every time you try to start it. The electronic chip in your key then responds with an individual code that must match the one found in the vehicle to start. If the codes don't match, the engine will shut down immediately and prevent theft of your vehicle.

Modern smart keys and fobs come with an embedded transponder, which stores electronic security information in a format that is not easily copied. When your key or fob is put into the ignition, it transmits the code to a device within the ECU. The ECU then compares it to the code stored in its memory, and activates the fuel system and ignition circuit if they match. If the codes don't match, the engine will not start even in the event that the ignition circuit is cut off by a criminal.

Replacing a lost or damaged key is a multi-stage procedure that involves precise cutting of the new blade for the key and programming it to connect with your car's immobiliser system. Every immobiliser system is unique and has its own unique programming procedure.
