The head of a key that contains a transponder chip is able to be removed to reveal an L-shaped key. Having a replacement key or fob that is made using transponder chips is a multi-stage process which includes precise cutting of replacement keys and programming of the transponder chip to synch up with the vehicle's immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that contains a set of windings (very fine wire coiled around tubes) which look similar to ones in an electric motor. These windings form a coded signal for the car to read. If the code is valid, then the car will allow you to start it.

There are two kinds of transponder chip, the one is known as the 80-bit, while the second is called the circle + (General Motors). The first can be reused, but has to be unlocked using a special machine in order to work on another compatible vehicle. The second kind is more difficult to use as the old keys can be damaged, broken or taken away when key cases are changed. However they can be used with a key-service that does not require batteries.

Immobiliser Systems

An immobiliser system is a digital security device that prevents thieves from starting your car. It operates by sending an electronic signal from your car to the key every time you attempt to start it. The electronic chip inside the key responds by sending a unique code that must match the one of the vehicle in order for it to start. If the codes aren't compatible, the engine will shut down immediately, and stop theft of your vehicle.

Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format that is not easily copied. When your key or fob is inserted into the ignition, it transmits this code to a receiver within the ECU. The ECU will then check it against the code stored in its memory and activates the fuel system and ignition circuit if they match. If the codes don't match, your engine will not start, even if an armed robber attempts to short-circuit the ignition circuit.

The procedure of replacing the fob or key requires an entire process that involves cutting the new key blade with precision and programming it to ensure that it can be synced with your car's system. There are many different immobiliser systems used in different years and models and each has its own distinct programming process. We use Ross-Tech software to ensure that your replacement key is programmed correctly for optimum performance and maximum security.
