Lexus remotes and fobs aren't easy to replace and require locksmiths who are skilled and possess the appropriate tools. Some models require the transponder within the key to be programmed to allow it to communicate with the immobiliser systems of the car. The lexus key shell replacement models employ different methods to program these chips. This is accomplished by using a specific device that transmits a specific code to the chip to unlock the doors or to start the engine.

Some Lexus cars are constructed with a single piece of hardware which includes the key head and the remote, and these are more simple to replace since there is no separate chip. This kind of key could also be a little less expensive.

Transponder Chips

More or less all new cars manufactured after 1995 have transponder chips within the head of the key to disable the immobiliser system. The head of a key which is equipped with a transponder chip may be removed to reveal a metallic 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's immobiliser.

A transponder is a type of chip with Non-Volatile Memory. It has a set of windings, which are fine wires wrapped around a tube. They look like the ones in an electric motor. These windings generate a signal for the car to read. If the code is correct the car will start.

There are two types of transponder chip, the first is called the 80-bit, while the second is known as the circle + (General Motors). The former type is reusable but needs to be unlocked by a specific machine in order to function in a different compatible vehicle. The latter is a bit more difficult because the previous keys are usually broken or drilled through, or discarded when key cases are replaced. They are able to be salvaged however and used with the service key, which doesn't need a battery to function.

Immobiliser Systems

An immobiliser system is a security measure that uses electronic technology that stops thieves from starting your vehicle. It works by sending an electronic signal from your car to the key each time you attempt to start it. The electronic chip inside the key responds by sending a unique code that must match the one of the vehicle to allow it to start. If the codes don't match, your engine will shut down immediately and prevent theft of your car.

Modern smart keys and fobs are equipped with embedded transponder chips that stores security information in a format that cannot be duplicated. When your key or fob is installed in the ignition it transmits this code to a device within the ECU. The ECU will then check it against the code that is stored in its memory and activates the ignition and fuel system circuit if they match. If the codes don't match, the engine won't be able to start - even if an armed robber attempts to short-circuit the ignition circuit.

Replacing a fob or a key is a multi-stage process that involves precise cutting of the new blade of the key and programming it to communicate with the immobiliser system of your vehicle. There are a variety of immobiliser systems used in different models and years and each has its own distinct programming process. We use Ross-Tech to ensure that the replacement key is correctly programmed. This will provide you with the best performance and security.
