Battery Replacement
It is possible to replace the battery if the key fob isn't locking or start your Lexus. This is a relatively simple procedure, and can be accomplished at home or at a dealership.

Make sure that your hands are dry and clean. Injecting moisture into the fob can damage or rust the battery you just bought. Open the key fob by pressing the release button on the side. Take off the mechanical key blade if it is present. Utilize a screwdriver or any other flat tool to break off the cover plate and expose the battery. Take the old battery off, and place a brand new CR1632 battery in place with its positive side facing up. Then, snap the fob together and you're ready to go!
