If you've got keys that has a chip inside it, the head comes with a cover that can be taken off to reveal an L-shaped key. The process of getting a replacement key fob made of a transponder chip is a multi-stage procedure that includes precise cutting of the replacement keys and programming the transponder chip to link up with the vehicle's immobiliser.

Transponders are chips that has Non-Volatile Memory. It has a set of windings which are delicate wires that are twisted around the tube. They resemble the ones in an electric motor. These windings create a coded message that the car can read. If the code is correct, the car will start.

There are two types of transponder chips. One is known as the 80 bit, and the other known as a circle + (General Motors). The first is reusable but must be delocked by a machine that is specially designed to function in a different compatible vehicle. The second kind is more difficult to use as the older ones could be damaged, drilled or thrown out when key cases are changed. They are able to be salvaged however, to use with an ad-hoc key that doesn't require batteries to operate.

Immobiliser Systems

An immobiliser system is a security measure that uses electronic technology that stops thieves from starting your vehicle. It works near by sending an electronic signal from the vehicle to your key each time you try to start it. The chip inside your key then responds with an individual code that must match that of the vehicle to start. If the codes don't match, your engine will shut down immediately and stop the theft of your vehicle.

Modern smart keys and fobs are equipped with an embedded transponder chip that stores electronic security in a format that cannot be duplicated. When your fob or key is put into the ignition, it transmits the code to a receiver within the ECU. The ECU then compares it to the code that is stored in its memory. It then activates the fuel system and ignition circuit if they match. If the codes don't match, the engine won't be able to start - even if an armed robber attempts to short-circuit the ignition circuit.
