Remotes

Replacing the Lexus remote or fob can be a complicated process and requires skilled locksmiths equipped with the right tools and experience. Certain models require the transponder within the key to be reprogrammed so that it can work with the immobiliser systems of the car. The chips are programmed using different methods based on the model of Lexus. This is done by using a special device that sends an indication to the chip that is compatible with the code used to unlock the doors and start the engine.

Some Lexus cars are designed with a unit that combines the key head and the remote. These are easier to replace lexus key because there is no chip that needs to be replaced. This kind of key may also be a bit less expensive.

Transponder Chips

More or less all new cars built since 1995 have transponder chips inside the key head that allow it to deactivate the immobiliser system. If you have a key with a chip, the head is covered in a plastic cover that can be pulled off to reveal an L-shaped metal key. Making a replacement key, or fob made with a transponder chip is a multi-stage process that includes precise cutting of key replacements and programming the transponder chip so that it can synch up with the vehicle's immobiliser system.

A transponder is an electronic chip that has Non-Volatile Memory (NVM) that houses a set of windings (very fine wire that is wrapped around a tube) which look similar to ones in an electric motor. These windings create a coded message that the car read. If the code is correct, then the car will allow you to start it up.

There are two kinds of transponder chips. The first is called the 80-bit, while the second is known as the circle + (General Motors). The first one can be reused, but has to be unlocked with a special machine to function on a different vehicle compatible with it. The latter type is more difficult since the earlier keys are usually damaged or drilled through, or thrown away when key cases are replaced. However, they can be used with a service-key that does not require batteries.

Immobiliser Systems

An immobiliser is a security measure that uses electronic technology that prevents thieves from starting your vehicle. It works by sending an electronic signal from the vehicle to the key each time you try to start it. The electronic chip in your key responds by sending a unique code which must match the one in the vehicle in order to start. If the codes do not match, your engine will shut down immediately to prevent theft.

Modern smart keys and fobs come with an embedded transponder chip that stores security information in a format that can't be easily duplicated. When your fob or key is put into the ignition, it transmits the code to a receiver inside the ECU. The ECU is then able to compare it with the code in its memory and activates the ignition and fuel system circuit if the two coincide. If the codes do not match, your engine will not start, even if a thief tries to short-circuit the ignition circuit.

The replacement of the fob or key involves a multi-stage procedure that includes cutting the new blade precisely and programming it to ensure that it syncs with the car's system. There are a variety of immobiliser systems used in different years and models and each one requires its own unique programming procedure. We use Ross-Tech software to ensure that your replacement key is programmed correctly to ensure optimal performance and security.
