Remotes

Lexus remotes and fobs aren't easy to replace and require locksmiths who are both experienced and possess the proper tools. Certain models require that the transponder chip in the key be reprogrammed in order to work with the car's immobiliser system. The Lexus models employ different methods to program these chips. This is accomplished by using an electronic device that transmits an indication to the chip that is compatible with the code used to open the doors and start the engine.

Certain Lexus cars are equipped with a single piece of hardware that includes the key head and the remote. These are much easier to replace because there is no separate chip. This type of key is also a bit cheaper.

Transponder Chips

Nearly all new cars made since 1995 include transponder chips embedded in the key head that allow it to deactivate the immobiliser system. If you've got keys with a chip inside, the head has a plastic cover which can be pulled off to reveal an 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 connect with the vehicle immobiliser.

A transponder is an electronic device with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire coiled around tubes) which look similar to ones in an electric motor. The windings generate a coded message that the car will read. If the code is correct the car will start.

There are two kinds of transponder chips. The first is called the 80-bit and the other is known as the circle + (General Motors). The first is reusable but needs to be unlocked by a machine that is specially designed to function in a different compatible vehicle. The second is more difficult to use as the older ones could be damaged, drilled or taken away when key cases are changed. However, they can be used with a key-service that doesn't require a battery.

Immobiliser Systems

Immobiliser systems are electronic security measures which prevent thieves from starting your vehicle. It works by sending an electronic signal from the car to the key each time you try to start it. The electronic chip in the key responds by transmitting a unique code that must match that of the vehicle to allow it to start. If the codes do not match, the engine will shut down immediately, preventing theft of your vehicle.

Modern smart keys and fobs have an embedded transponder which stores electronic security information in a format which is not easily copied. When your key or fob is inserted into the ignition, it transmits this code to a receiver within the ECU. The ECU is able to compare this code with the one stored in its memory, and then activates both the fuel system as well as the ignition circuit if they match. If the codes do not match, your engine won't start - even if someone tries to short-circuit the ignition circuit.
