Remotes Replacing a Lexus remote or fob can be a complicated process and requires skilled locksmiths who have the right tools and expertise. Some models require the transponder in the key to be changed in order to function with the immobiliser system in the car. The Lexus models employ different methods to program these chips. This is accomplished by using an instrument that sends an electronic signal to the chip that matches the code used to open the doors and start the engine. Some Lexus models are built with a device that combines the key head and remote. They are much easier to replace since there is no chip that needs to be replaced.

Transponder Chips Nearly all new cars made since 1995 include transponder chips in the key head to disarm the immobiliser system. If you've got a key with a chip, the head is covered in a plastic cover that can be pulled off to reveal an L-shaped metal key. A transponder-chip replacement key or fob is a multistage process. It involves cutting the keys with precision and programming the chip to communicate with the vehicle's immobiliser. A transponder is a chip with Non-Volatile Memory. It has a set windings, which are fine wires coiled around a tube. They look like the ones 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, one known as the 80 bit, and the other referred to as a circle + (General Motors). The first is reusable, but must be delocked using a specific machine in order to work on another compatible vehicle. The latter one is more difficult as the old keys are usually broken and then drilled through or thrown away when key cases are replaced. However, they can be used with a service-key which does not require batteries. Immobiliser Systems An immobiliser system is an electronic security measure that deters thieves from starting your vehicle. It operates by sending a signal from the vehicle to your key when you attempt 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 match, the engine will shut down immediately, and stop theft of your car. Modern smart keys and fobs contain an embedded transponder which stores electronic security information in a format that can't be copied easily. When your fob or key is placed in the ignition, it transmits the code to a receiver within the ECU. The ECU analyzes this code in comparison to the one stored in its memory, and activates both the fuel system and the ignition circuit if they match. If the codes don't match, the engine won't be able to start – even if someone tries to short-circuit the ignition circuit. Replacing a fob or key is a multi-stage procedure that requires precise cutting of the new blade of the key and programming it to work with the immobiliser system of your vehicle. Each immobiliser system is distinct and has its own programming procedure. We utilize Ross-Tech software to ensure that your replacement key is programmed correctly for optimal performance and security.
