How to replace the Hyundai Kona key fob battery 2018-2019

Replacing the battery on the Kona key fob requires a small screwdriver kit to replace the CR2032 battery. I like this kit from Amazon here:

You’ll need a small flathead screwdriver to pop open the outer case it two spots. Be careful to pop open both spots! If you just try to pry open one side, you’ll likely break the plastic on the key fob as you can see I did on my first attempt:

Once you have the fob plastic shell open, there are two small Phillips screws to remove to get access to the battery. Once you’ve removed those, take your small flathead and pry out the CR2032 battery. Put in a fresh new CR2032 coin battery and you’re all set! Screw back on the battery cover and pop the outer plastic shell back in place and you’re all set. You’ve successfully replaced the battery on your Hyundai Kona key fob! Great work!
