Hyundai Sonata Key Fob Battery Remote Replacement (2006 – 2020)

The Hyundai Sonata has been the top luxury 4-door sedan of the brand for what seems like ages. It was the first car that made me consider buying a Hyundai (even though a rival brand would dub it [“So not a” car]). Over the years, it has used four different types of key fobs. The “D-Shaped”, “Flip”, “Rectangular”, and “3-Button Grey Hatch” key fobs. All use the same internal CR2032 coin battery.

For other Hyundai models, see our Hyundai key fob battery page.

In this video, I'm going to show you how to change the internal battery in a Hyundai Sonata key Fob. This key Fob was used between 2015 and 2020 and uses a CR 2032 battery. You can find these batteries online and do this entire process at home. It's very simple. You can just order them on Amazon for a couple of dollars and they'll come right to your door.

I'll leave a link in the description if you're interested, and then you'll be able to follow along and do this yourself. So let's start by taking the key Fob and pressing on this button to release the internal key. Put that to the side. And now looking in, we can see the keyhole. And then right next to it, this little slot.

We're going to put a flathead screwdriver into that slot to separate the two halves of the key Fob. So right here is the keyhole. And then here's the slot. Insert your flathead into the slot and just make a twist like that to separate the two halves of the key Fob. And then you can just pull it apart with your fingers.

Here we have the battery inside of its housing, and I can't really remove it with my fingers. I'm going to use a precision screwdriver. You can get a pack of these on Amazon for just a couple of Bucks if you want to safely remove your battery. I'll leave a link in the description for that. Otherwise, you can use a toothpick or another similarly sized tool.

What we're going to do is target this top right area and insert our tool all the way down to the bottom, getting under the battery and just prying it out, wiggling and prying it out and it will pop right out. So go ahead and get a brand new CR 2032 battery. Make sure this positive side with the battery information goes face down and just position it into its housing. Pushing the bottom down first into this little metal component, and then pushing on the top of the battery to push it flush into place. Now we just reconnect two halves of the key Fob, clicking them back together and the battery will come on.

If you have some juice in there and you'll know that you did everything just right. So if this video helped you out feel to leave a like and for more information, or to see the full guide on the Hyundai Sonata, click the link in the description to go to fobbattery.com. Thank you for watching.

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 Sonata key fob! Great work!

First step, hold down the button on the front of the key fob to remove the internal key. With your key gone, you can see a slot just beneath the key-hole. Take a flat-head screwdriver, insert it into the slot, and twist. The two halves of the key fob will come apart.

Now, take your precision screwdriver or other thin tool and use it to pry the battery out. Come in from the right side of the battery, push down to the bottom, and gently pull the tool back until the battery pops out. Take a new CR2032 battery and put it into place face-down. Push it down until it clicks into place.

Finally, push the two halves of the key fob back together and put back the internal key. If the battery has power, the light on the front of the key should turn on when you push a button.

Here we have the hole that the key just came from. And then above it a little slot that's for opening the battery. So we're going to take a flathead screwdriver, insert it into that slot, just twist gently. As you can see, the key Fob is coming apart. Now we can just finish it with our fingers, set this part to the side, and then we're going to come in and try to remove this battery.

It's in a little plastic housing. And I'm going to use this precision screwdriver to remove it. You can get some of these on Amazon for just a couple of Bucks. I'll leave a link in the description. They're really good for safely removing the battery without scratching it or damaging it.

Otherwise, you could use maybe a toothpick, something you have lying around. We're going to come in on the side of the battery and with our tool, push all the way down to the bottom and pry getting under the battery and it'll pop right out. Okay. So now go ahead, get a brand new CR 2032. And when you're putting it in, make sure that the positive side with the battery information goes down into this little compartment.

And now we're going to push it down into plate into this little metal component before clicking the top end, positioning it, pushing it down and just clicking the top in. And it will sit in there nicely and know that you're good to go. So let's just click the two halves. Let me show you if this circuit board kind of is coming out. It's just a little rubber thing with the circuit board in it.

And this is what you see. Just make sure these little things are the buttons go right on top of there, gently position it in place, click these back together.

Very simple. And now just return your key and you're done. That's it. If this video helped you out, feel free to leave a like and for more information, click the link in the description to go to fobbattery.com to see the entire guide on the Hyundai Sonata and the key Fobs. Thank you for watching.

In this video, I will show you how to change the internal battery in this Hyundai Sonata key Fob. This particular key Fob was used between 2006 and 2014 and uses a CR 2032 battery. Changing your battery is very simple and it can be done at home. All you'll need is a flathead screwdriver and one of these batteries. If you'd like to get one online, I'll leave a link in the description to get it on Amazon.

It's just a couple Bucks and it'll come right to your door and then you can follow along. So let's start just by looking at the top of the key Fob for this little slot. That's for opening it up. We're going to put a flathead screwdriver into this slot, gently twist, just until the whole thing comes apart, or until you get a little separation on the side like that. And then you can continue working down twisting and it will all come apart.

The circuit board might come out like this. It might just be positioned in there. I'll just show you how to put it all back together at the end. So we're going to take this out. Now we have the battery CR 2032, and we're going to need to push it out of place.

I'm going to use my flathead screwdriver and just push it until I can remove it with my fingers. Now take a new CR 2032 battery. Make sure that this positive side with the battery information goes up and simply slide it down under this piece of metal all the way down until it kind of sticks in place. Now, if it all comes apart on you, just make sure you put this side of the circuit board into this little rubber thing. So the battery is facing up and that should just fit in nicely.

And then this goes on top of these buttons here. If the buttons fall out, go ahead and put this one in. First two are connected. It's very simple. And then you can take your trunk key, turn it over and see.

Okay, that side goes up, that side goes up. Just flip it carefully, position it in place, and then it will all live flush there. And you know that you're good to go. You just put this on top of those little buttons and should click everything back together and the light will come on showing you that everything is positioned and your battery has juice.
