Keys
Lexus keys aren't easy to replace. A specialist locksmith is required to create an alternative that functions. This is due to the fact that every Lexus key is equipped with a microchip that needs to be programmed to work in conjunction with your vehicle's immobiliser If it is not, the car will not start.
It requires a lot of time and specialized equipment for this procedure to be completed correctly. Each model has its own procedure for programming. Replacing keys or remotes is a pricey task that should be left to experts, unless equipped with the proper tools and expertise.

Remotes
Replacing a Lexus remote or fob is a complicated process and requires skilled locksmiths equipped with the right tools as well as knowledge. Some models require that the chip inside 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 an instrument that sends an indication to the chip which matches the code used to open the doors and start the engine.
Certain Lexus vehicles are equipped with a unit that combines the key head and the remote. These are easier to replace, as there is no separate chip to replace. This kind of key could also be a bit less expensive.
All fobs eventually lose their battery power, regardless of the type of key. This is a stressful situation, but it's possible to get your Lexus back to normal with a little knowledge.

Transponder Chips
More or less all new cars since 1995 have transponder chips within the key head to disable the immobiliser system. If you've got keys with a chip in it the head is covered in a plastic cover that can be pulled off to reveal an L-shaped key. A transponder-chip replacement key, also known as a fob is a multi-stage procedure. It involves cutting the keys precisely and programming the chip to make it sync with the vehicle immobiliser.
A transponder is a chip that has 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. These windings generate a signal that the car can read. If the code is correct, the car will start.
There are two kinds of transponder chip. The one is known as the 80-bit and the second is called the circle + (General Motors). The first one is reusable, but must be removed using a special machine in order to work on a different vehicle compatible with it. The latter is more difficult as the old ones are often broken or drilled through, or thrown away when key cases are replaced. However, they can be used with a service-key that doesn't require a battery.
Immobiliser Systems
Immobiliser systems are electronic security devices that stop thieves from starting your vehicle. It operates by sending an electronic signal from the car to the key every time you try to start it. The chip inside your key responds by sending an individual code that must match that of the vehicle to start. If the codes don't coincide, your engine will stop immediately to stop theft.
Modern smart keys and fobs are equipped with an embedded transponder, which stores electronic security information in a format which can't be copied easily. When the key or fob is inserted into the ignition, they send this code to the ECU. The ECU is able to compare this code with the one it has stored in its memory, and activates both the fuel system and the ignition circuit if they are compatible. If the codes do not match, your engine will not start, even if a burglar tries to short-circuit the ignition circuit.
Replacing a fob or a key is a multi-stage procedure that requires precise cutting of the new key blade, and programming it to work with the immobiliser system of your vehicle. Each immobiliser system is unique and has its own unique programming procedure.
