Keys
Lexus keys aren't easy to replace and require a professional car key replacement locksmith to create a spare working. This is because every Lexus key has an electronic chip that needs to be programmed to sync with your vehicle's immobiliser system and if it's not, it'll not start.
This process takes time and requires special equipment to perform right, and each model has a distinct programing procedure. Replacing a key or a remote fob is a costly job and should be left to professionals unless you have the proper tools and knowledge.
You'll need to replace the batteries in your smart key or standard key. Both keys function by turning the barrel of the ignition. You can save money by doing this yourself, but it requires a small Phillips screwdriver and a coin (a 20p piece works best) and a paperclip.

Remove the fob, which will reveal an indentation that is circular where the metal key will be. Take the battery out with the help of a paperclip.

Remotes
Lexus remotes and fobs can be difficult to replace and require locksmiths who are both experienced and possess the proper tools. Some models require that the transponder chip in the key be programmed to function with the vehicle's immobiliser system. The chips are programmed with different methods depending on the model of Lexus. This is accomplished making use of a special device that sends a code to the chip to unlock the doors or to start the engine.
Certain Lexus cars are designed with a key head that is a combination of the key head and remote. They are easy to replace, as there is no separate chip to replace. This kind of key could also be a little cheaper.

Transponder Chips
Nearly all new cars manufactured after 1995 have transponder chips in the key head to disable the immobiliser system. The head of a key that is equipped with a transponder chip may be removed to reveal an L-shaped key. Having a replacement key or fob that is made using a transponder chip is a multi-stage process that includes accurate cutting of the replacement keys and programming the transponder chip to link up with the vehicle's immobiliser.
A transponder is an electronic chip with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire wrapped around a tube) that resemble ones found in an electric motor. These windings form a coded signal that the car can read. If the code is correct then the car will allow you to start it.
There are two types of transponder chips. One called the 80 bit and the other one is called a circle + (General Motors). The first kind is reusable, however it needs to be delocked using a specific machine to function on another compatible vehicle. The second type is more difficult to use due to the fact that the old ones can be damaged, broken or thrown out when key cases are changed. However, lexus key fob can be used with a service-key which doesn't require a battery.
Immobiliser Systems
Immobiliser systems are electronic security measures which prevent thieves from starting your car. It operates by sending an electronic signal from the vehicle to your key each time you try to start it. The electronic chip inside the key responds by sending a unique code which must match that of the vehicle to allow it to start. If the codes do not coincide, your engine will immediately shut down to prevent theft.
Modern smart keys and fobs are equipped with an embedded transponder chip that stores electronic security in a format that can't be easily duplicated. When the key or fob is inserted into the ignition, they transmit this code to the ECU. The ECU examines the code against the one in its memory and activates both the fuel system and the ignition circuit if they are compatible. If the codes don't match the engine won't start even if the ignition circuit is damaged by a thief.
Replacing a lost or damaged key is a multi-stage process which involves precise cutting the new key blade, and programming it to synch with your car's immobiliser system. Each immobiliser system is distinct and has its own unique programming procedure. We employ Ross-Tech to ensure that the replacement key is correctly programmed.
