What you will need:
• 1x CR2032 battery
• Flat-head screwdriver
• Precision screwdriver (3.0mm/PH0 or smaller)
-or-
• Pen, pencil, toothpick or another thin tool

First, let’s get that internal key removed. Push on the button on the bottom of the key fob to release the internal key. Directly next to the keyhole, there is a groove in the plastic like a small slot. Take a flat-head screwdriver and insert it into this slot. Twist the screwdriver and the two halves of the key fob will pop apart.

Now, locate the battery. You will need a small screwdriver or similar tool to remove the battery. Try to get your tool under the battery and pull it out with a prying motion. The battery will pop out. Take a new CR2032 battery and click it into place face-down. Reattach the two halves of the key fob and put your internal key back inside. Press on one of the buttons and make sure the red light on the front of the key fob comes on. If it does, you’re all set. Well done!
