Keys

Lexus keys can be difficult to replace. A specialist locksmith is needed to make an original replacement that works. This is due to the fact that every Lexus key is equipped with a microchip that needs to be programmed to sync with the immobiliser of your vehicle If it is not, the car will not start.

Remotes

Replacing the Lexus remote or fob can be complicated and requires expert locksmiths with both the right tools and experience. Certain models require that the transponder chip within the key be changed in order to work with the immobiliser of the car. The Lexus models use different methods to program these chips. This is accomplished by using a special device which transmits a code to the chip to unlock the doors or start the engine.

Some Lexus vehicles are equipped with a unit that combines the key head and remote. They are much easier to replace since there is no separate chip needed. This kind of key may also be a little less expensive.

All fobs eventually lose their battery power, regardless of the kind of key. It can be a frustrating experience, but with a little know-how you can get your Lexus back in operation. Check out the owner's manual to determine which battery type you require. Then, locate a replacement. Find tiny holes on the inside of the fob, and insert coins (a 20p piece is ideal) and twist.

Transponder Chips

Nearly all new cars manufactured after 1995 have transponder chips within the key head that allow it to deactivate the immobiliser system. If you have a key that has a chip inside it, the head is covered in a plastic cover which can be pulled off to reveal an L-shaped metal key. Having a replacement key or fob with transponder chips is a multi-stage method that includes accurate cutting of the replacement keys as well as programming the transponder chip to synch up with the vehicle's immobiliser.

These windings transmit a message that the car can read. If the code is correct then the car will allow you to start it up.

There are two kinds of transponder chips. One known as the 80 bit, and the other one is called a circle + (General Motors). The first is reusable, but must be unlocked using a special machine in order to work in a different vehicle that is compatible. The second kind is more difficult to use due to the fact that the older keys could be damaged, broken or removed when key cases are changed. They can be salvaged, however and then used to create the service key, which doesn't require batteries to function.

Immobiliser Systems

An immobiliser system is an electronic security feature which prevents thieves from opening your car. It works by sending an electronic signal from the car to the key every time you try to start it. The electronic chip inside your key then responds with an unique code that must match the one found in the vehicle in order to start. If the codes aren't compatible, the engine will shut down immediately, preventing theft of your car.

Modern smart keys and fobs come with embedded transponder chips that stores security information in a format that can't be duplicated. When the fob or key is inserted into the ignition, they transmit this code to the ECU. The ECU then compares it to the code stored in its memory and activates the fuel system and ignition circuit if they coincide. If the codes don't match, the engine will not start, even if an armed robber attempts to short-circuit the ignition circuit.

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