If you have a key with a chip in it the head is covered in a plastic cover that can be pulled off to reveal an L-shaped metal key. A replacement key or fob made of transponder chips is a multi-stage process which includes precise cutting of the replacement keys as well as programming the transponder chip in order to synch up with the vehicle's immobiliser system.

A transponder is a chip with Non-Volatile Memory. It has a set of windings, which are delicate wires that are twisted around a tube. They resemble the ones in an electric motor. These windings form a coded signal for the car to read. If the code is correct the car will begin to move.

There are two types of transponder chip. The first is called the 80-bit and the other is called the circle + (General Motors). The first is reusable but needs to be unlocked by a special machine to function in a compatible vehicle. The second kind is more difficult to use because the older keys could be broken, drilled, or thrown out when key cases are changed. They are able to be salvaged however and used with a service key that doesn't need a battery to function.

Immobiliser Systems

Immobiliser systems are electronic security devices that deter thieves from starting up your vehicle. It operates by sending a signal from your car to the key when you attempt to start it. The 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 match, the 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 that is not easily copied. When the fob or key are placed in the ignition, they send this code to the ECU. The ECU will then check it against the code stored in its memory and then activates the ignition system and fuel circuit if the two coincide. If the codes do not match, the engine will not start, even when the ignition circuit has been damaged by a thief.

The replacement of the fob or key requires a multi-stage procedure that includes cutting the new blade precisely and programming it to ensure that it can be synced with your car's system. Every immobiliser system is unique and has its own programming procedure.
