Both of these take a CR2032 battery which is very easy to replace at home. In this guide, we’ll show you everything you need to know to change your battery DIY.

How to replace the Hyundai Kona “Egg-Shaped” smart key fob battery (2018, 2019, 2020)

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

What you will need:
• 1x CR2032 battery
• Flat-head screwdriver

To open your key fob, first remove the internal key. Pull the little lever on the back of the fob and pull it out. Under the hole that the key came from, there is an indentation or slot. Insert a flat-head screwdriver into the slot and twist to separate the two halves of the key fob. Pull the pieces of plastic apart until you have access to the inside.

Use your screwdriver to push on the bottom of the battery. Push until the battery comes free. Take a new CR2032 battery and slide it into place just as it was before. Make sure your battery is face-up. Now, just click the two halves of your key fob back together and you’re done. No so bad, was it?

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 flat-head 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 flat-head 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!
