Opening the Key Fob

With the back piece removed, you can now see the battery. Removing it is very simple. Just push on the bottom of the battery with your finger, and it will slide right out.
It’s important to note that the battery type is a CR2016. Make sure you use the same type when replacing it.
Inserting the New Battery
Now that the old battery is out, it’s time to insert the new one. Take your CR2016 battery and make sure the positive side is facing up.
Slide the battery down into the slot and click the top in place. Ensure that the plus side is still facing up before proceeding.
Reassembling the Key Fob
All that’s left to do now is to click the two halves of the key fob back together. Line up the pieces and press them until they snap into place.
Your key fob should now be working with a fresh battery. Test it to make sure everything is functioning correctly.
