Remotes Lexus remotes and fobs can be difficult to replace and require locksmiths who are knowledgeable and have the right tools. Certain models require that the transponder chip within the key be reprogrammed to function with the immobiliser of the car. The chips are programmed with different methods, based on the model of Lexus. This is done using a specific device that sends an indication to the chip that matches the code used to open the doors and start the engine. Some Lexus vehicles are equipped with a key head that is a combination of the key head and remote. They are simpler to replace, since there is no separate chip to replace.

Transponder Chips Most new cars manufactured after 1995 have transponder chips within the key head to disable the immobiliser system.

Having a replacement key or fob that is made using transponder chips is a multi-stage process that includes precise cutting of the replacement keys as well as programming the transponder chip in order to synch up with the vehicle's immobiliser. A transponder is a device with Non-Volatile Memory. It contains a set windings that are delicate wires that are twisted around a tube. They look similar to those in an electric motor. These windings generate a signal that the car can 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 and the other is known as the circle + (General Motors). The former is reusable but it needs to be unlocked by a special machine to work in another compatible vehicle. The latter one is more difficult since the earlier ones are often broken, drilled through or discarded after key cases are replaced. They can be salvaged however and used with a service key that doesn't need a battery to function. Immobiliser Systems An immobiliser system is an electronic security measure that deters thieves from starting your vehicle. It works by sending an electronic signal from your car to your key each time you attempt to start it. The chip inside the key responds with a unique code which must match the one found in the vehicle in order to start. If the codes do not match, the engine will immediately shut down to prevent theft. Modern smart keys and fobs come with an embedded transponder which stores electronic security information in a format which cannot be easily copied. When the fob or key are placed in the ignition, they transmit this code to the ECU. The ECU examines the code against the one it has stored in its memory, and then activates the fuel system and the ignition circuit if they match. If the codes don't match, the engine won't start – even if a thief tries to short-circuit the ignition circuit. The procedure of replacing a key or fob involves multiple steps that include cutting the new key blade precisely and programming it so that it can be synced with your car's security system. Each immobiliser is unique and has its own programming procedure.
