In this quick tutorial, I will show you how you can change the battery for your Subaru Forester key Fob at home. It's very easy to do. All you will need is one of these CR 1620 batteries and a regular flathead screwdriver. The first step is to look to the key ring here on this device. In this top corner.

You can see there's a little indentation in the plastic. We are going to put our flathead screwdriver into that area and just twist, just turning like a key. And you can see now I've started to open up this device and in that separation between the two halves of the key Fob, I'm going to continue twisting. Working my way down to the back comes off very easily. I can set that to the side here.

I'm going to dump out this component with the buttons inside here. We will find the battery. So the next step is to kind of release this little plastic locking mechanism. It's really easy to do. We're just going to hold the sides of the device and we're just going to put the corner of our flathead screwdriver under this little piece of plastic and just kind of push it up.

And on the first one, it's not going to feel like much. But as you continue to do this, moving on to the second one, put the corner in, pushing kind of prying. You can feel it's starting to loosen up there. And here on the third one, there we go. Now it's really opening up

You can see that. And we can just go and finish it on number four, put the corner in wiggling, wiggling. Pushing that one is feeling a little tough. So I'm actually just going to go ahead and pull it apart with my fingers. Came off really easily.

As you saw. It doesn't take much. You'll get a hang of it just getting and kind of freeing those little locking mechanisms. It's not too hard. Now here we have the battery and if you're looking with this metal component facing down, going to come in on the top left, right here with the flathead screwdriver.

Again, using the corner, we're just going to get under the battery and lift it out and you'll see it kind of pops out there. This is it a 1620 battery, 1620. So take a brand new one, make sure the positive side that has the text on it goes face down and you'll just push that into place. And now we can just put everything back together here. So set this on, click it back together.

Take your key here.

Make sure this is sitting flush in there before you try to attach the back piece of plastic back on there and just give it a click. Squeeze firmly until it clicks into place and you are all set.

In this quick tutorial, I will show you how you can change the battery in your Subaru Forester key Fob this device takes one CR 2032 battery to run and all we will need to open it up and change the battery is a regular flathead screwdriver. First step here is to pick up the device, flip it over, and you want to push down this little silver button to remove your internal key. My key is missing, but you will just hold this down, pull the key out, and now set that to the side. Now looking in here we have the keyhole where the key just came from.

And then there's this kind of little L shape. We're going to insert the flathead screwdriver in the little bottom part of that L. That's kind of parallel to this keyhole. So right there and now holding the device firmly but not squeezing too much, we're just going to twist and you heard that kind of popping sound. That was the back part of this device coming off.

So just pull it apart with your fingers. You can send this to the side and I'm going to kind of gently dump this component out. This is our circuit board and our battery. So I'm going to always hold it from the sides. I don't want to touch this too much.

You don't want to damage anything. So just holding this from the sides, we're going to take the very same flathead screwdriver and put the corner in between the battery and this piece of plastic here. So hold this firmly and just start to push in there, apply some constant pressure and just maybe even wiggling and prying a little bit. And once you slide under the battery, it will pop right out. Here we are CR 2032.

Take a nice brand new battery and make sure this positive side, the one that has the text on it that we're looking at right now that goes face up. So slide that into place and click it just like you saw. You want to slide down towards the bottom and click the top end. From here, you can see on this back piece of plastic, there's a little image of a battery right there going to put the battery right on top of that so that the circuit board is facing up. Be careful with this.

If you just turn this over, you might lose your buttons. This little piece of rubber that holds the buttons down will fall out. So when we put this all back together, we're just kind of going to bring them together like that. So nothing falls out and you just squeeze it back together. You can click and check that the light does come on.

And that means you did everything right and you are now good to go. I hope that video helped you out.

If you want to pick up one of these batteries online, get it sent right to your door. I will leave a link down the description to get one on Amazon for just a couple of Bucks and then just follow along through the easy to do. The first step is just to flip this thing over to the back and we're going to remove these screws.

Something about this size will work. If you don't have a screwdriver that's this small, I'd recommend something like this. This is a pack of precision screwdrivers. You can get them. I'll leave a link down the description as well.

They're a couple of Bucks on Amazon and they have multiple sizes of flathead and Phillips head and help you to open this thing up really easily. Can be handy around the house too. But once you have your battery and your screwdriver, go ahead and follow along and we're just going to pull these things out.

Don't drop your screwdriver, just pull them out carefully. Set them to the side. Don't want to lose these. And once we have the second screw out, we can remove the back piece of plastic here and there. Our battery.

We're just going to gently slide it out with our thumb. And once it comes free, you can get rid of your old dead battery and take a brand new CR 2032 battery. Make sure this positive side that has the text on it goes face up and then just slide it into place until it clicks in just like that. And now you want to click this back on and turn in these two little screws.

Go ahead and reattach these things. You don't need to go too tight. Just make sure it's going to be nice and secure. And that's pretty much all it takes. Your light should now come on showing you that your battery is fully charged and that you did everything right and so good.

Yeah, there you go. Now you're good to go. I hope that helped you out. And if it did, feel free to let me know down in the comment section or just by giving this video a like.
