Remotes

Replacing a lexus key shell remote or fob is complicated and requires skilled locksmiths who have the right tools and knowledge. Certain models require that the chip inside the key be changed to function with the immobiliser of the car. These chips are programmed by different methods, based on the model of Lexus. This is done by using a special device which sends a code to the chip to unlock the doors or to start the engine.

Some Lexus automobiles are built with a single unit which includes the key head and remote. These are more simple to replace since there is no separate chip. This type of key is also less expensive.

Transponder Chips

Transponder chips are present in the key heads of almost all new cars built since 1995. They can be used to disable immobiliser systems. If you've got keys with a chip, the head is covered in a plastic cover that can be pulled off to reveal an L-shaped metal key. A transponder-chip replacement key or fob is a multistage process. It involves cutting the keys with precision and programming the chip to make it sync with the vehicle's immobiliser.

A transponder is a chip with Non-Volatile Memory. It has a set windings, which are very fine wires wrapped around the tube. They look similar to those in an electric motor. These windings produce a coded message that the car will read. If the code is valid, then the car will allow you to start it.

There are two kinds of transponder chips. The first is called the 80-bit while the other is known as the circle + (General Motors). The former is reusable but must be delocked by a special machine to function in a compatible vehicle. The latter is a bit more difficult as the old keys are usually damaged and drilled or discarded when key cases are replaced. However they can be used with a service-key that doesn't require a battery.

Immobiliser Systems

An immobiliser is an electronic security feature that prevents thieves from starting your car. It operates by sending an electronic signal from the vehicle to the key whenever you try to start it. The electronic chip in the key responds by sending a unique number of codes that must match the one of the vehicle to allow it to start. If the codes don't match, your engine will shut off immediately to stop theft.

Modern smart keys and fobs have embedded transponder chips that stores security information in a format that cannot be duplicated. When the fob or key is inserted into the ignition, they transmit this code to the ECU. The ECU compares this code with the one stored in its memory and activates both the fuel system as well as the ignition circuit if they match. If the codes don't match then the engine will not start, even if the ignition circuit is short-circuited by a thief.

Replacing a lost or damaged key is a multi-stage procedure which involves precise cutting the new blade of the key and programming it to communicate with the immobiliser system of your vehicle. Each immobiliser system is unique and has its own unique programming procedure.
