Remotes Lexus remotes and fobs aren't easy to replace and require locksmiths who are knowledgeable and have the right tools. thekeylab.co.uk require the transponder in the key to be programmed to allow it to communicate with the immobiliser of the vehicle. The Lexus models use different methods to program these chips. This is accomplished using a special device which sends a code to the chip to unlock the doors or to start the engine. Certain Lexus models are built with a unit that combines the key head and remote. They are easy to replace, since there is no separate chip needed.

Transponder Chips Transponder chips are found in the key heads of a majority of new vehicles manufactured after 1995. They can be used to disarm immobiliser systems. The head of a key that contains a transponder chip is able to be removed to reveal an L-shaped key. A replacement key or fob made with transponder chips is a multi-stage process which includes precise cutting of the key replacements and programming the transponder chip to synch up with the vehicle's immobiliser. A transponder is a device with Non-Volatile Memory. It has a set of windings that are fine wires wrapped around the tube. They look similar to those in an electric motor. The windings are coded to create a signal for the car to read. If the code is correct it will allow the car to start. There are two types of transponder chips, one known as the 80 bit and the other one is called a circle + (General Motors). The former is reusable but must be delocked with a special device to function in a different compatible vehicle. The latter is more difficult since the earlier ones are often broken and drilled or thrown away when key cases are replaced. However, they can be utilized with a service key that does not require batteries. Immobiliser Systems Immobiliser systems are electronic security devices which prevent thieves from starting up your vehicle. It works by sending an electronic signal from the car to your key each time you attempt to start it. The electronic chip in the key responds with an unique code that must match that of the vehicle to start. If the codes don't match, the engine will stop immediately, preventing theft of your vehicle. Modern smart keys and fobs come with an embedded transponder that stores electronic security information in a format that is not easily copied. When your fob or key is placed in the ignition, it transmits the code to a receiver in the ECU. The ECU analyzes this code in comparison to the one in its memory and activates the fuel system and the ignition circuit if they match. If the codes don't match, your engine will not start, even if a burglar tries to short-circuit the ignition circuit. The replacement of the fob or key requires multiple steps that include cutting the new blade precisely and programming it so that it is compatible with your car's system. Each immobiliser system is unique and has its own unique programming procedure. We utilize Ross-Tech to ensure that the replacement key is programmed correctly.
