1. Gather the necessary tools. You will need a small Phillips head screwdriver, a new CR2032 battery, and a pair of tweezers.
2. Remove the old battery. Use the Phillips head screwdriver to remove the two screws that hold the key fob together. Then, carefully pry open the case with your fingers or the tweezers. Be careful not to lose the small spring that is located inside the fob.
3. Insert the new battery. Place the new CR2032 battery into the fob, with the positive side facing up. Make sure that the battery is properly seated in the compartment.
4. Reassemble the key fob. Replace the spring and the back cover of the fob, and then secure it with the two screws.
5. Test the key fob. Press the buttons on the key fob to make sure that they are working properly.
If the key fob is still not working, you may need to have it reprogrammed by a locksmith or a Toyota dealership.

- Make sure that you purchase the correct type of battery for your key fob. The battery type is usually printed on the back of the fob.
