This is accomplished by using an instrument that sends a signal to the chip that matches the code used to unlock the doors and start the engine.

Certain Lexus automobiles are built with a single unit that includes the key head as well as the remote, and these are easier to replace since no separate chip is required. This type of key can also be a little less expensive.

Transponder Chips

Transponder chips are found in the head of the key on almost all 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 a metallic L-shaped key. Making a replacement key, or fob with a transponder chip is a multi-stage procedure that involves precise cutting of replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire wrapped around the tube) which look similar to ones found in an electric motor. These windings produce a coded message that the car read. If the code is correct then the car will allow you to start it.

There are two types of transponder chip. The one is known as the 80-bit and the other is called the circle + (General Motors). The former is reusable however it must be unlocked by a special machine to function in a different compatible vehicle. The second is more difficult to use because the older ones could be damaged, drilled or removed when key cases are changed. They can be salvaged however and used with an ad-hoc key that does not require a battery to function.

Immobiliser Systems

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

Modern smart keys and fobs are equipped with an embedded transponder that stores electronic security information in a format which can't be copied easily. When your fob or key is inserted into the ignition, it transmits this code to a device within the ECU. The ECU will then check it against the code in its memory and activates the ignition and fuel system circuit if the two match. If the codes don't match, the engine will not start even when the ignition circuit has been cut off by a criminal.

Replacing a fob or key is a multi-stage procedure that requires precise cutting of the new blade for the key and programming it to synch with your car's immobiliser system. There are a variety of immobiliser systems that are used in different models and years and each one requires an individual programming procedure. We use Ross-Tech software to ensure that your replacement key is programmed correctly to ensure the best performance and security.
