In this quick tutorial, I will show you how you can change the battery in your Subaru Impreza key Fob. This device was used since 2015 all the way up to present day, and it takes just one of these CR 2032 batteries to run. If you want to pick one of these up online, I'll leave a link down in the description to get one on Amazon for just a couple of bucks, come right to your door and then you can just follow along and get this thing done super easily. The first step here is just to turn this device over to the back, hold down the silver button, and then we will remove the internal key.

As you can see, I don't have the key right now, but you will just remove the internal key and set to the side. And then looking at the area that the key just came from. Here we have the keyhole right above it. There's another little parallel slot here's the keyhole. And then we're going in right here.

Insert your flathead screwdriver into that area and just twist. You can hear a little popping sound. And that is the back of this device coming off. So now I'm just going to continue working through that opening that I just made, twisting until the back comes off nice and easily. Set that to the side.

And now you can just remove this or kind of dump it out gently. Set this down for now. Here we have the circuit board and the battery component. So I'm just going to hold this on the sides. I don't want to touch the back.

There any of that delicate stuff there. And what we're going to do is use the same flathead screwdriver and come in with the corner of the screwdriver right in between the battery and the plastic housing. So just pushing in and then applying a little bit of pressure and kind of twisting, the battery will pop right out. And here is our CR 2032 battery again. If you want to pick one of these up, I will leave a link down in the description for you to get one.

Probably the cheapest price available. It's just a couple of bucks on Amazon. So when you have your battery, make sure the positive side of the text goes face up and you want to push it down towards the bottom part here. First line that up and then click the top in. If you do it the other way around, get the top in first.

It won't move. You'll be pushing really hard. It's not going to come in. So just down and then click the top. Picking up the back of the device here, you can see that little image of the battery there.

We're going to set the battery right on top of that with the circuit board facing up. And when you're handling this part, be careful because if I were to just turn this over, this rubber component would fall out and so with these little buttons, this little piece of plastic for the buttons. So what we want to do is kind of just put them together gently and carefully put it back together. You can put your key back inside and that is it. You can just make sure the light turns on, make sure you did everything right and you are good to go.

GIF Visual Guide

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 to change the battery in your Subaru Legacy key Fob. This particular device was used between 2006 and 2008, and it takes just one of these CR 1620 batteries to run. If you don't know where to get this battery, you can actually pick one up online. So I will leave a link down in the description to get one on Amazon for just a couple of bucks. It's probably the lowest price out there and you don't have to go shopping around, so it's pretty convenient.

The only other things you will need is a regular old flathead screwdriver. And you will need a smaller Phillips head screwdriver, one that is the right size to remove this screw. So I will be using a rather small precision screwdriver. If you do not have a Phillips head small enough to remove this screw, I would recommend something like this. It's just a little pack of precision screwdrivers.

You have your Phillips head and flathead of different sizes. This is also just a couple of bucks. And I will put a link on the description to get it on Amazon if you're interested. And once you have everything you need, you can just follow along here. So what we're going to do is just remove that small screw to start and just remove that, set it to the side.

You don't want to lose it. And you can probably just pull this part with your fingers. But if it's been many years, if it's a little bit old, it can be kind of gunked up or stuck there. So what I like to do is just take the flathead screwdriver and push in. So there's like a little space between the battery and the plastic there.

If you just kind of put the corner of your tool in there and just push and wiggle, you will get under there and just be able to lift this piece off very easily. Now set the back to the side, and inside we have this little component that we will be removing. So you can just kind of knock it out, push on the buttons on the front if you would like, just to loosen it to get this part out. Now set this to the side and we will just be opening this up by targeting the bottom here with our flathead screwdriver. And you can see there's this little kind of latch that's holding it into place.

I'm going to go under it and just kind of push and wiggle like that until we can remove these. Now set this aside. You don't want this rubber component coming out. Your buttons will fall out. So just kind of keep this nice and together.

Set that to the side. And now we can turn our attention here to the battery again with the corner of our flathead screwdriver. I'm just going to come in from the top and just get under the battery with the corner and lift it up just very gently the battery will pop out. Just need to lift it up a little prying motion. Here is our 1620 battery again.

If you don't know where to pick this up I will leave a link down in the description for you to get one for just a couple of bucks and once you have a new one make sure you are putting the positive side face down. Yes, positive side facing down. Click it into place just like that and now we can just carefully start to reassemble the device so click this part back together so that it's locked and secure. Set this back inside, push it all the way down and now we can set the back into place and when you're doing this the keyring is here. You actually want to connect that first.

There's kind of a little latch on the top so you get that and then push down. If you go from the bottom first this part will not close so make sure you are hooking on to this little latch right there and then pushing down and the last step of course is to put our small screw back in there and just twist it to a finger tightness. I say you don't need to screw it too tight just enough to hold this thing together nicely like that and there we go. All our buttons are working. We have a new battery in there and we are good to go so if that video helped you out feel free to let me know down in the comments section or just by giving this video a like and if you ever need help changing a battery in any of your key Fob no matter the maker model you can check out the rest of our videos here on YouTube or visit us at fobbattery.com.

Subaru Key Fobs — Everything You Need to Know

Gone are the days when drivers needed to always carry their car’s ignition key. Thanks to advanced programming, we have moved onto the next new step.

Subaru keyless entry remotes are pretty much a standard with vehicles from Subaru Inc. As with any fob, you’ll need to know how to program it and replace its battery.

If you have a Subaru make and remote, then you’ve come to the right place. Reading this guide will help you get all the details you need to keep driving and save money.

What Are Subaru Keyless Entry Remotes?

Subaru’s keyless entry remote allows you to access your car without even touching its car ignition key.

The brand uses two Subaru keyless entry fobs — which one you get will depend on the model of your car. The traditional metal car key will not be visible to you, because it will hide inside the remote as a backup option.

How Does the Subaru Key Fob Work?

When you click a button, your Subaru key fob sends a unique code to your vehicle’s receiver. This interaction activates the locking mechanism of your car. Most fobs also use a code generator that features almost unlimited and unique entry codes.

Advantages of having a Subaru remote key fob

  • Perfect when you’re in a hurry, your Subaru key fob will control your vehicle even from your pocket, purse, or bag.
  • Your vehicle remains secure as you can only access it when the car key remote is nearby. You can also use it to quickly lock all the doors on your vehicle as soon as you need to.
  • A new cutting-edge remote and start system is available on many new models of Subaru vehicles. They allow you to hop into your vehicle and get the ignition started as easily as pulling open its doors and clicking a button.
  • Many Subaru models will beep when you use your key fob to unlock it. The sound is helpful when you’re looking for your car in a crowded parking lot and don’t remember where you left your vehicle.
  • Most of these remotes come with code architecture as an added security feature. Please set a unique code and share it only with those you trust.
