Keys

Lexus keys aren't simple to replace and require a specialist locksmith for car keys to create a working spare. Every Lexus key comes with a microchip which must be programmed in order to work with the immobiliser system in your vehicle.

It requires a lot of time and specialized equipment to allow this procedure to be completed correctly. Each model has its own specific programming process.

Remove the fob and you will see an indentation that is circular for the key made from metal, take the battery out (using the paperclip) and then insert the new one, making sure it's the correct way up. Clip the inside of the key back to.

Remotes

Lexus remotes and fobs can be difficult to replace and require locksmiths who are both well-versed and have the proper tools. Certain models require that the chip inside the key be reprogrammed in order to work with the vehicle's immobiliser system. The chips are programmed with different methods based on the model of lexus car key. This is done by using an instrument that sends an indication to the chip that matches the code used to open the doors and start the engine.

Certain Lexus models are built with a device that combines the key head and the remote. They are easy to replace, since there is no separate chip required. This kind of key could also be a bit cheaper.

Transponder Chips

More or less all new cars made since 1995 include transponder chips within the key head to disarm the immobiliser system. The head of a key that has a transponder chip can be removed to reveal a metal L-shaped key. A transponder-chip replacement key or fob is a process that involves multiple stages. It involves cutting keys precisely and programming the chip to sync up with the vehicle immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that contains a set of windings (very fine wire coiled around a tube) that resemble ones found in an electric motor. These windings produce a coded message that the car read. If the code is correct the car will start.

There are two kinds of transponder chip. The one is known as the 80-bit, while the second is known as the circle + (General Motors). The first one is reusable, but it must be removed using a special machine to function on another compatible vehicle. The latter one is more difficult as the old ones are often broken or drilled through, or discarded after key cases are replaced. However, they can be used with a service-key which doesn't require a battery.

Immobiliser Systems

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

Modern smart keys and fobs contain an embedded transponder which stores electronic security information in a format which is not easily copied. When the fob or key are placed in the ignition, they send this code to the ECU. The ECU analyzes this code in comparison to the one stored in its memory, and then activates both the fuel system and the ignition circuit if they are compatible. If the codes don't match and the engine does not start, even in the event that 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 of the key and programming it to work with the immobiliser system of your vehicle. There are a variety of immobiliser systems that are used in different models and years and each one requires its own distinct programming process. We use Ross-Tech software to ensure that your replacement key is programmed correctly for maximum performance and security.
