Transponder chips are present in the key heads of a majority of new cars manufactured since 1995. They can be used to disable immobiliser systems. The head of a key that is equipped with a transponder chip may be removed to reveal an L-shaped key. Making a replacement key, or fob made with transponder chips is a multi-stage process that includes precise cutting of replacement keys as well as programming the transponder chip in order to synch up with the vehicle's immobiliser.

A transponder is a chip that has Non-Volatile Memory. It has a set of windings which are fine wires coiled around a tube. They look like those in an electric motor. These windings create 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 types of transponder chip, the first is called the 80-bit while the other is known as the circle + (General Motors). The first type is reusable, but it must be unlocked using a special machine to function on another compatible vehicle. The latter type is more difficult as the old keys are usually damaged or drilled through, or thrown away when key cases are replaced.

Immobiliser Systems

An immobiliser is an electronic security feature that stops thieves from starting your car. It works by sending an electronic signal from the car to the key every time you try to start it. The electronic chip in your key responds by sending an individual code that must match the one in the vehicle to start. If the codes don't match, the engine will shut off immediately to prevent theft.

Modern smart keys and fobs have an embedded transponder chip that stores security information in a format that cannot be easily duplicated. When your key or fob is put into the ignition, it transmits this code to a receiver in the ECU. The ECU is then able to compare 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 will not start even in the event that the ignition circuit is cut off by a criminal.

The replacement of a key or fob involves an entire process that involves cutting the new blade precisely and programming it to ensure that it syncs with the car's system. Each immobiliser is unique and has its own programming procedure. We use Ross-Tech software to ensure that your replacement key is programmed correctly for optimal performance and security.
