Remotes

Lexus remotes and fobs aren't easy to replace and require locksmiths who are both experienced and possess the proper tools. Some models require that the transponder chip in the key be programmed in order to work with the car's immobiliser system. The Lexus models employ different methods to program these chips. This is done by using a special device which sends a code chip to unlock the doors or start the engine.

Some Lexus cars are equipped with a single piece of hardware which includes the key head and the remote, and these are more simple to replace since there is no separate chip. This kind of key is also less expensive.

Transponder Chips

Nearly all new cars built since 1995 have transponder chips in the key head that allow it to deactivate the immobiliser system. If you've got a key with a chip, the head is covered in a plastic cover that can be taken off to reveal an L-shaped key. The process of getting a replacement key fob made with a transponder chip is a multi-stage method that includes precise cutting of the replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser system.

A transponder is a chip that has Non-Volatile Memory. It contains a set windings that are fine wires wrapped around a tube. They look like those in an electric motor. These windings generate a signal for the car to read. If the code is correct, then the car will allow you to start it up.

There are two types of transponder chips, one known as the 80 bit and the other referred to as a circle + (General Motors). The first is reusable but it needs to be unlocked by a specific machine in order to be used in a compatible vehicle. The second is more difficult to use since the old ones can be damaged, drilled or toss out when keycases are changed. They can be salvaged, however for use with an ad-hoc key that doesn't require batteries to function.

Immobiliser Systems

An immobiliser is a digital security device that prevents thieves from starting your vehicle. It works by sending an electronic signal from the car to your key each time you try to start it. The electronic chip in 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 do not coincide, your engine will shut down immediately to stop theft.

Modern smart keys and fobs have an embedded transponder chip that stores electronic security in a format that cannot be duplicated. When your key or fob is installed in the ignition it transmits this code to a receiver inside the ECU. The ECU compares this code with the one in its memory, and then activates both the fuel system and the ignition circuit if they match. If the codes do not match the engine won't start, even if the ignition circuit is short-circuited by a burglar.

Replacing a fob or a key is a multi-stage procedure that involves precise cutting of the new blade for the key and programming it to communicate with your car's immobiliser system. Each immobiliser system is distinct and has its own programming procedure. We utilize Ross-Tech to ensure that the replacement key is correctly programmed.
