Remotes
Lexus remotes and fobs can be difficult to replace and require locksmiths who are both skilled and possess the appropriate tools. Some models require that the transponder chip contained in the key be programmed in order to work with the vehicle's immobiliser system. The Lexus models employ different methods to program these chips. This is done using a special device that transmits a specific code to the chip to unlock the doors or start the engine.
Some Lexus cars are equipped with a single unit that includes the key head as well as the remote, and these are simpler to replace as no separate chip is required. This type of key can also be a little cheaper.

Transponder Chips
Transponder chips are present in the key heads of almost all new cars produced since 1995. They are used to disarm immobiliser systems. The head of a key which is equipped with a transponder chip may be removed to reveal a metallic L-shaped key. The process of getting a replacement key fob made of a transponder chip is a multi-stage method 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 equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire coiled around a tube) which look similar to ones found in an electric motor. These windings transmit a message that the car will read. If the code is correct the car will begin to move.
There are two types of transponder chips. The first is called the 80-bit and the second is called the circle + (General Motors). The former can be reused but must be delocked by a specific machine in order to work in another compatible vehicle. The latter one is more difficult as the old keys are usually broken and then drilled through or discarded after key cases are replaced. They are able to be salvaged however for use with a service key that doesn't require a battery in order to function.
Immobiliser Systems
An immobiliser system is an electronic security feature that stops thieves from starting your car. It operates by sending a signal from the vehicle to your key when you attempt to start it. The electronic chip inside your key responds by sending a unique code that must match that of the vehicle in order to start. If the codes don't match, your engine will immediately shut down to prevent theft.
Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format that can't be copied easily. When the key or fob are inserted in the ignition, they transmit this code to the ECU. The ECU then compares it to the code in its memory and then activates the ignition and fuel system circuit if they match. If the codes do not match, your engine will not start - even if someone tries to short-circuit the ignition circuit.
The replacement of the fob or key requires a multi-stage procedure that includes cutting the new blade accurately and programming it to ensure that it is compatible with your car's systems. There are a variety of immobiliser systems that are used in different years and models and each has the use of a unique programming method.
