Carefully remove the old battery: Note the orientation of the positive (+) and negative (-) sides.

Common Issues When Replacing a Toyota Key Fob Battery:

The key fob still doesn’t work: If you’ve replaced the battery correctly and the key fob still doesn’t work, there may be a more serious issue, such as a malfunctioning key fob. In this case, you’ll need to contact your Toyota dealership or a qualified mechanic.
The key fob casing is difficult to open: If you’re having trouble opening the casing, try using a thinner screwdriver or applying gentle pressure in different spots.
