Remotes

Replacing the Lexus remote or fob can be a complicated process and requires skilled locksmiths who have the right tools as well as knowledge. Certain models require the transponder inside the key to be programmed in order to function with the immobiliser system in the car. The lexus locked keys in car models use different methods to program these chips. This is done using a specific device that sends a code to the chip to unlock the doors or to start the engine.

Some Lexus automobiles are built with a single piece of hardware that consists of the key head and remote, and these are simpler to replace as there is no separate chip. This type of key is also less expensive.

Transponder Chips

Transponder chips are present in the keys of nearly all new cars manufactured since 1995. They are used to disable immobiliser systems. The head of a key that includes a transponder chips can be removed to reveal a metallic L-shaped key. Making a replacement key, or fob with transponder chips is a multi-stage process which includes precise cutting of replacement keys and programming of the transponder chip in order to synch up with the vehicle's immobiliser system.

Transponders are chips with Non-Volatile Memory. It contains a set windings, which are very fine wires wrapped around a tube. They look similar to those in an electric motor. 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 is called the 80 bit and the other referred to as a circle + (General Motors). The first is reusable, but must be unlocked using a special machine to function on a different vehicle compatible with it. The second is more difficult to use since the older ones could be broken, drilled or thrown out when key cases are changed. However, they can be used with a key-service that does not require batteries.

Immobiliser Systems

Immobiliser systems are electronic security measures that stop thieves from starting up your vehicle. It works by sending a signal from your vehicle to your key lexus when you attempt to start it. The electronic chip in the key responds by sending a unique code which must match that of the vehicle to allow it to start. If the codes don't match, the engine will shut down immediately to prevent theft.

Modern smart keys and fobs are equipped with embedded transponder chips that stores electronic security in a format that cannot be duplicated. When the key or fob are placed in the ignition, they send this code to the ECU. The ECU will then check it against the code that is stored in its memory. It then activates the ignition system and fuel circuit if the two coincide. If the codes do not match, the engine won't be able to start - even if someone tries to short-circuit the ignition circuit.

Replacing a fob or a key is a multi-stage procedure which involves precise cutting the new key blade, and programming it to communicate with your car's immobiliser system. There are a variety of immobiliser systems that are used in different years and models, and each requires an individual programming procedure.
