Some models require that the transponder chip contained in the key be changed to function with the immobiliser system of the car. The Lexus models use different methods to program these chips. This is done by using a special device which transmits a code to the chip to unlock the doors or start the engine.
Certain Lexus cars are equipped with a single piece of hardware that consists of the key head as well as the remote, and these are much easier to replace because no separate chip is required. This type of key is also a bit cheaper.

The process of getting a replacement key fob made of transponder chips is a multi-stage process which includes precise cutting of the key replacements and programming the transponder chip in order to synch up with the vehicle's immobiliser.
A transponder is a device with Non-Volatile Memory. It is comprised of a set of windings, which are delicate wires that are twisted around the tube. They look like those in an electric motor. The windings generate a coded message that the car is able to read. If the code is correct the car will begin to move.
There are two types of transponder chips. The one is known as the 80-bit, while the second is known as the circle + (General Motors). The first type is reusable, but it must be unlocked using a special machine to function in a different vehicle that is compatible. The latter one is more difficult since the earlier keys are usually broken and drilled or discarded after key cases are replaced. They are able to be salvaged however and used with the service key, which doesn't require batteries to function.
Immobiliser Systems
Immobiliser systems are electronic security measures which prevent thieves from starting your vehicle. It works by sending a signal from your vehicle to the key when you attempt to start it. The electronic chip inside your key then responds with a unique code which must match the one in the vehicle in order to start. If the codes aren't compatible, the engine will shut down immediately, preventing theft of your vehicle.
Modern smart keys and fobs are equipped with embedded transponder chips that stores electronic security in a format that cannot be duplicated. When your fob or key is put into the ignition, it transmits this code to a device within the ECU. The ECU then compares it to the code stored in its memory. It then activates the fuel system and ignition circuit if the two coincide. If the codes do not match then the engine will not start even when the ignition circuit is short-circuited by a burglar.
The procedure of replacing keys or fobs involves a multi-stage procedure that includes cutting the new blade accurately and programming it so that it can be synced with your car's systems. There are a variety of immobiliser systems that are used in different models and years and each one requires its own distinct programming process.
