If you’ve got a key that has a chip inside it, the head comes with a cover that can be pulled off to reveal an L-shaped key. The process of getting a replacement key fob made with transponder chips is a multi-stage procedure that involves precise cutting of key replacements and programming the transponder chip so that it can synch up with the vehicle’s immobiliser system.

A transponder is an electronic chip with Non-Volatile Memory (NVM) that contains a set of windings (very fine wire twisted around the tube) which look similar to ones found in an electric motor. These windings create a coded message that the car can read. If the code is correct it will allow the car to start.

There are two kinds of transponder chips. One 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 compatible vehicle. The second one is more difficult to use because the old ones can be broken, drilled or taken away when key cases are changed. However, they can be utilized with a service key that doesn’t require a battery.

Immobiliser Systems

Immobiliser systems are electronic security measures that deter thieves from starting your vehicle. It operates by sending a signal from the vehicle to the key when you attempt to start it. The electronic chip inside the key responds by transmitting a unique code that must match the one of the vehicle to allow it to start. If the codes do not match, the engine will shut down immediately, preventing theft of your car.

Modern smart keys and fobs come with an embedded transponder which stores electronic security information in a format that can’t be copied easily. When the fob or key are placed in the ignition, they transmit this code to the ECU. The ECU then compares it with the code in its memory. It then activates the fuel system and ignition circuit if the two coincide. If the codes do not match, the engine won’t start – even if an armed robber attempts to short-circuit the ignition circuit.

The process of replacing a key or fob involves a multi-stage process that includes cutting the new blade accurately and programming it so that it syncs with your car’s systems.
