First, look at the top of the key fob where the key ring attaches. You’ll see a small indentation in the plastic.

Insert the screwdriver behind the battery at the top and pry it out. Hold the battery with your thumb to prevent it from flying out.

Take your new CR2016 battery and ensure the positive side is facing up. Click it into place.
