The fob can be removed to reveal a circular indentation for the key made of metal. Take the battery out (using the paperclip) and then put in the new one making sure it's the correct way up. Then, clip the inside of the key back to the fob.

Remotes

Replacing a Lexus remote or fob can be difficult and requires skilled locksmiths who have the right tools as well as knowledge. Some models require the transponder within the key to be programmed to allow it to communicate with the immobiliser system in the car. These chips are programmed by different methods depending on the model of Lexus. This is accomplished using a special device which sends a code chip to unlock the doors or start the engine.

Some Lexus vehicles are designed with a system that combines the key head and the remote. These are easier to replace because there is no separate chip to replace. This kind of key could also be a bit less expensive.

Transponder Chips

Most new cars manufactured after 1995 have transponder chips embedded in the key head to disable the immobiliser system. The head of a key that contains a transponder chip is able to be removed to reveal a metallic L-shaped key. Making  lexus key fob replacement , or fob with transponder chips is a multi-stage process which includes precise cutting of the key replacements and programming the transponder chip to link up with the vehicle's immobiliser system.

A transponder is a type of chip that has Non-Volatile Memory. It has a set windings which are fine wires wrapped around a tube. They look similar to those in an electric motor. These windings create a coded message that the car will 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 can be reused, but has to be unlocked with a special machine to function in a different vehicle that is compatible. The latter type is more difficult as the old keys are usually broken or drilled through, or discarded 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 that deter thieves from starting your car. It operates by sending an electronic signal from the car to your key each time you try to start it. The chip inside the key responds with an unique code that must match the one found in the vehicle to start. If the codes do not match, your engine will shut off immediately to prevent theft.

Modern smart keys and fobs are equipped with embedded transponder chips that stores electronic security in a format that can't be duplicated. When the fob or key are inserted in the ignition, they send this code to the ECU. The ECU analyzes this code in comparison to the one it has 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, the engine will not start - even if someone tries to short-circuit the ignition circuit.

The replacement of the fob or key requires a multi-stage procedure that includes cutting the new blade with precision and programming it so that it works with your car's security system. Every immobiliser system is unique and has its own programming procedure. We employ Ross-Tech to ensure that the replacement key is programmed correctly.
