What you will need:

  • 1x CR2450 battery
  • Flat-head screwdriver

Start by pressing the silver button on the side of the key fob to release the internal key. Next, look at the bottom of the device, there are two openings next to the keyhole, along the seam of the back piece of plastic. Take a flathead screwdriver and push it into an opening and, with a prying motion, pop off the back of the key fob.

From here, you can remove the battery with your fingers. Take a new CR2450 battery and slide it into place, positive side up. All that’s left to do is click the back of the device back on. It’s that simple!
