If you've got keys that has a chip inside it, the head is covered in a plastic cover that is able to be pulled 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 accurate cutting of the replacement keys and programming the transponder chip to link up with the vehicle's immobiliser system.

A transponder is a device that has Non-Volatile Memory. It has a set windings that are fine wires that are wrapped around the tube. They look like the ones in an electric motor. The windings generate a coded message that the car will read. If the code is correct, then the car will allow you to start it.

There are two kinds of transponder chip. The first is called the 80-bit, while the second is called the circle + (General Motors). The former can be reused but needs to be unlocked by a machine that is specially designed to be used in a compatible vehicle. The latter one is more difficult since the earlier keys are usually broken and then drilled through or thrown away when key cases are replaced. However, they can be used with a key-service that does not require batteries.

Immobiliser Systems

Immobiliser systems are electronic security measures that prevent thieves from starting your vehicle. It operates by sending an electronic signal from your car to your key each time you try to start it. The electronic chip inside your key responds by sending a unique code that must match that of the vehicle in order to start. If the codes do not match, the engine will immediately shut down to stop theft.

Modern smart keys and fobs are equipped with an embedded transponder that stores electronic security information in a format which cannot be easily copied. When your key or fob is installed in the ignition it transmits this code to a receiver inside the ECU. The ECU then compares it to the code that is stored in its memory and activates the ignition system and fuel circuit if they match. If the codes do not match then the engine will not start even when the ignition circuit has been short-circuited by a burglar.

The procedure of replacing a key or fob involves a multi-stage procedure that includes cutting the new key 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 unique programming procedure. We employ Ross-Tech to ensure that the replacement key is programmed correctly.
