Scroll down to see a full video tutorial or keep reading for a step by step guide.

What you will need:

Look at the bottom of the key fob. Next to the key ring, there is a small slot along the seam in the plastic. Take a regular flathead screwdriver, insert it into the slot, and twist. You will hear a pop and feel the back of the device start to come off. Remove this piece with your fingers.

Now, looking at the battery housing, find the small arrow pointing towards an opening. Take a precision flathead screwdriver and insert it into this opening and pry the battery out. Take a new CR2450 battery and slide it into the housing, positive side up. The last thing—just click the back of the key fob back on. That’s it, your device is working again and ready to go!
