First, use a flat head screwdriver to gently pry open the key fob. Then, remove the old battery and replace it with a new CR2032 battery. Make sure the positive (+) side of the battery is facing up. Finally, snap the key fob back together.

Before opening the key fob, make sure you have a replacement battery on hand. If the key fob isn't snapped closed properly, it may not work. It's always a good idea to have a spare key in case of emergencies.
