In this video, I will show you how to change the internal battery in a Hyundai Kona key Fob. This key Fob was used from 2018 all the way up to present day 2020 and uses a CR 2032 battery. You can change this battery very simply, simply at home. All you'll need is a flathead screwdriver and one of these CR 2032 batteries. If you'd like to buy one online.

I've left a link down the description to get it on Amazon. It's just a few dollars and then we can start. So turn the key Fob over, find this little latch and push that down to remove your internal key. Inside, we can see the keyhole that the key just came from and then a slot right next to it. We're going to take our flathead screwdriver, insert it into that slot and twist and the two halves of the key Fob should begin to come apart.

You can just work your way down that opening with your twisting, careful not to do what I did in scratch inside, so you can just gently twist, pull it apart with your fingers. Set this to the side right now. And now to remove this battery, you can just push on it with your finger or use your tool to get it all the way out. Now take a new CR 2032 battery. Make sure the positive side with the text is facing up and insert it back into this area just like that, pushing it all the way down into place.

All that's left to do is connect the two halves of the key Fob back together. You can see that the light is working, meaning your battery has juice and you're good to go. That's really all it takes.

What you will need:
• 1x CR2032 battery
• Flat-head screwdriver
• Precision screwdriver (3.0mm/PH0 or smaller)
-or-
• Pen, pencil, toothpick or another thin tool

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:

Buy Small Screwdriver Set on Amazon

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!

All right, so in this video, I'm going to show you how to change the battery on a Hyundai Kona key Fob. And this is the flip key model here is 2018 - 2019. This flip key. The key to this is there's two small indentations on this side of the key. So we flip the inner key open to get access to the battery.

You'll take a small flathead screwdriver. If you have a little mini screwdriver set, something like this, it's really handy. I can all link to that in the video. And there's two spots where you can pry apart the back of the case here. So there's one right here, and then there's one down here.

So be careful to get both of these. And so stick in the flathead screwdriver. Just kind of pop that back off there and then again down at the bottom here. Same thing in that spot. And you'll be able to pry off this back part and get access to the inner part of the battery.

And from here, there are two small Phillips screws to get access to the battery that we need to change. So stick small Phillips screwdriver and you can get a little kit like this for a couple of bucks on Amazon has some Philips and flathead screwdrivers. So just unscrew the two small Phillips screws here, and this will get you access to the internal part where we can change the battery on our key Fob here. So once we've gotten those unscrewed, we'll see the battery type here and positive side is up. And this is a CR 2032.

It's a very common button battery. And to get access to this, this is in here pretty tight. So you'll need to take your small flathead and just kind of try to pull it with your fingers and then get underneath. So pull it one way underneath, and then you'll be able to slide out the battery and then pop in. A new CR 2032 slips in there pretty easily reattach.

This part here covers the battery. This kind of slides in down here at the bottom, and then go ahead and screw the top in like so tighten those down. You can reattach the backing here, and this will just pop back in. And again, there are two spots here that we prided apart. And be careful you don't crack the back here like I did, because I thought there was only one spot here.

But again, there's two indentations if you can see there and there to insert your flathead, pry this off. There you go. That's how you replace the CR 2032 battery in a Hyundai Kona 2018 - 2019.
