Transponder Chips

Transponder chips are present in the head of the key on almost all new vehicles manufactured after 1995. They can be used to disarm immobiliser systems. The head of a key that has a transponder chip can be removed to reveal a metallic L-shaped key. A transponder-chip replacement key, also known as a fob is a process that involves multiple stages. It involves cutting the keys accurately and programming the chip to sync up with the vehicle's immobiliser.

A transponder is a chip that has Non-Volatile Memory. It is comprised of a set of windings, which are very delicate wires that are twisted around the tube. They look like the ones in an electric motor. These windings produce a coded message that the car read. If the code is valid, then the car will allow you to start it up.

There are two types of transponder chips. One known as the 80 bit and the other is known as a circle + (General Motors). The former can be reused but needs to be unlocked with a special device to function in a compatible vehicle. The second type is more difficult to use due to the fact that the old ones can be damaged, drilled or removed when key cases are changed. They can be salvaged, however and then used to create the service key, which doesn't require a battery in order to function.

Immobiliser Systems

An immobiliser system is a security measure that uses electronic technology that prevents thieves from starting your vehicle. It works by sending a signal from your car to the key when you attempt to start it. The electronic chip in the key responds by sending a unique code that must match that of the vehicle to allow it to start. If the codes do not match, the engine will shut down immediately and prevent theft of your car.

Modern smart keys and fobs contain an embedded transponder that stores electronic security information in a format that can't be copied easily. When your key or fob is inserted into the ignition, it transmits this code to a device within the ECU. The ECU then compares it with the code stored in its memory and activates the ignition system and fuel circuit if the two match. If the codes don't match the engine won't start, even if the ignition circuit is short-circuited by a thief.

Replacing a fob or key is a multi-stage process that requires precise cutting of the new key blade and programming it to connect with the immobiliser system of your vehicle.
