Locate the screw on the bottom of the key fob where the key ring is. Use a precision screwdriver to remove the screw. Next, with the key fob face-up, push up on the key ring until the section with the buttons comes free.

Now you will need to push down on one of the buttons to separate the face of the key fob from the batter housing underneath. Look to the right side of this piece and locate the small slot in the center. Insert a flat-head screwdriver into the slot and twist. The compartment will open revealing the battery. Use your screwdriver to gently pry the battery out.

Next, take a new CR1616 battery and push it into place face-down. Finally, reassemble the key fob and put the screw back in. Boom, you did it! Nice work, your key fob is ready to go.
