Keys Lexus keys are not simple to replace and require a specialist locksmith to replace your car key to make a working spare. Each Lexus key is equipped with an embedded microchip that must be programmed to communicate with the immobiliser system of your vehicle. It takes a lot time and special equipment for this procedure to be completed correctly. Each model has its own programming procedure. Replacing remotes or keys is a pricey task that should be left to professionals, unless you are equipped with the proper tools and expertise.

Remotes Replacing a Lexus remote or fob can be an extremely complex process that requires expert locksmiths with both the right tools as well as knowledge. Certain models require that the transponder chip within the key be changed in order to work with the vehicle's immobiliser system. These chips are programmed by different methods depending on the model of Lexus. This is accomplished by using a special device that sends a signal to the chip that is compatible with the code used to open the doors and start the engine. Certain Lexus automobiles are built with a single unit that incorporates the key head and the remote. These are easier to replace since no separate chip is required. This kind of key is also a bit less expensive. Regardless of the key type no matter what type of key it is, all fobs eventually run out of battery power. It can be quite frustrating, but with a little bit of knowledge you can get your Lexus back to normal.

Transponder Chips Transponder chips are found in the key heads of almost all new vehicles manufactured after 1995. They are used to disable immobiliser systems. If you have a key that has a chip inside it, the head is covered with a plastic cover which can be pulled off to reveal an L-shaped metal key. Having a replacement key or fob made of transponder chips is a multi-stage process that includes precise cutting of the replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser. A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire coiled around tubes) that resemble ones found in an electric motor. These windings generate a signal that the car can read. If the code is correct the car will start. There are two types of transponder chips. One is called the 80 bit and the other known as a circle + (General Motors). The first one is reusable, however it needs to be removed using a special machine in order to work in a different vehicle that is compatible. The latter one is more difficult, as the older ones are often broken and drilled or discarded after key cases are replaced. They can be salvaged, however and used with the service key, which doesn't require a battery in order to function. Immobiliser Systems An immobiliser system is an electronic security measure that prevents thieves from starting your car. It operates by sending a signal from your car to the key when you attempt to start it. The electronic chip inside the key responds by transmitting a unique code that must match the one of the vehicle in order for it to start. If the codes don't match, the engine will shut down immediately and prevent theft of your car. Modern smart keys and fobs come with an embedded transponder, which stores electronic security information in a format which is not easily copied. When the key or fob are inserted into the ignition, they send this code to the ECU. The ECU is able to compare this code with the one it has stored in its memory, and it activates both the fuel system as well as the ignition circuit if they are compatible. If the codes don't match, the engine will not start even when the ignition circuit has been short-circuited by a burglar. The procedure of replacing a key or fob involves a multi-stage procedure that includes cutting the new key blade with precision and programming it to ensure that it can be synced with your car's security system. There are many different immobiliser systems that are used in different models and years and each one requires the use of a unique programming method. We utilize Ross-Tech software to ensure that your replacement key is programmed correctly to ensure the best performance and security.
