Remotes
Replacing a Lexus remote or fob is difficult and requires skilled locksmiths with the right tools and expertise. Certain models require the transponder within the key to be reprogrammed so that it can work with the immobiliser systems of the car. The Lexus models employ different methods to program these chips. This is accomplished by using a special device which sends a code chip to unlock the doors or to start the engine.
Some Lexus cars are designed with a unit that combines the key head and the remote. These are easier to replace because there is no separate chip required. This kind of key may also be a bit cheaper.

Transponder Chips
Transponder chips are found in the key heads of a majority of new vehicles manufactured after 1995. They are used to disable immobiliser systems. If you have a key with a chip in it the head comes with a cover that can be taken off to reveal an L-shaped key. A transponder chip replacement key or fob is a multi-stage process. It involves cutting the keys accurately and programming the chip to communicate with the vehicle immobiliser.
A transponder is a chip with Non-Volatile Memory. replace lexus key contains a set windings which are fine wires wrapped around a tube. They look similar to those in an electric motor. These windings generate a signal for the car to read. If the code is correct the car will start.
There are two types of transponder chips. The first is called the 80-bit, while the second is called the circle + (General Motors). The former is reusable but must be delocked by a specific machine in order to be used in a compatible vehicle. The latter type is more difficult since the earlier keys are usually damaged and drilled or discarded after key cases are replaced. They are able to be salvaged however and then used to create the service key, which doesn't require batteries to function.
Immobiliser Systems
Immobiliser systems are electronic security devices that deter thieves from starting your vehicle. It operates by sending an electronic signal from the car to the key whenever you try to start it. The electronic chip in the key responds with an individual code that must match the one in the vehicle in order to start. If the codes do not coincide, your engine will immediately shut down to prevent theft.
Modern smart keys and fobs have an embedded transponder which stores electronic security information in a format which can't be copied easily. When your key or fob is inserted into the ignition, it transmits the code to a device within the ECU. The ECU then compares it with the code stored in its memory, and activates the fuel system and ignition circuit if they match. If the codes don't match, your engine won't be able to start - even if an armed robber attempts to short-circuit the ignition circuit.
The replacement of the fob or key requires multiple steps that include cutting the new blade precisely and programming it so that it works with your car's systems.
