To replace the battery in the key, the tool only needs a screwdriver.
The first thing to do is to remove the bottom cover of the Toyota Camry VI key. A special pase is provided for this purpose and is at the key. After the cover is removed, you must remove the central part of the key.
To access the battery, you must detach the transparent plastic cover. You're gonna need a screwdriver that's comfortable with this. You can then change the battery that is also removed using a screwdriver. It's going backwards.
