What you will need:

Start by pressing the silver button on the side of the key fob to release the internal key. Next, look at the bottom of the device, there are two openings next to the keyhole, along the seam of the back piece of plastic. Take a flathead screwdriver and push it into an opening and, with a prying motion, pop off the back of the key fob.

From here, you can remove the battery with your fingers. Take a new CR2450 battery and slide it into place, positive side up. All that’s left to do is click the back of the device back on. It’s that simple!

In this video, I will show you how to change the internal battery in this Ram 3500 key Fob. This key Fob takes one CR 2450 battery. You can get these online. I'll put a link in the description if you'd like to get one on Amazon for just a couple of bucks. And then let's get right into it.

First thing, find this button on the right side of the key Fob. Hold it down and remove your internal key. Now this back part is what we're going to be lifting off. It's just a thin piece of plastic. If you look up close here, what we have are two little holes, one on the left and one on the right.

We're going to use something like a precision screwdriver. This is the easiest way, the safest way you could use a regular screwdriver. I'll show you how to do both. But if you want to get something like this, you can get a pack of these on Amazon for just a couple of bucks. I will also leave that in the description if you're interested.

And so what we do is we go into the hole, push it in, and then kind of lift up, pry up until we hear a pop, and you can see that the left side is starting to come off. Now we'll do the same thing over here on the right. You can come into this whole or into this opening that you've created. And what we want to do is just lift up, go inside, and then lift up. And once you've made another opening on the right side, you should be able to just pull it apart with your fingers.

Now, if you want to use a big screwdriver, it's the same thing. Just be careful. You want to wiggle into that area with the hole. And once you have one inside, a little bit twist or turn like a key, just gently until you hear that pop come in on the other side, turn. And now we are in from here.

All we need to do is pull the battery down and then we can get at it with our fingernails. Or you can use your screwdriver and take out the old battery. Get yourself a new CR 2450 battery and put it in positive side up just like that. And then push it down and up just like that. Now, last thing, we are just going to click the back of the key Fob back into place and go ahead and put your key back in.

And that is all it takes. You are all set and ready to go. I hope you found this video helpful. And if you did, feel free to leave a like or a comment.

In this video, I will show you how to change the internal battery in this Ram 3500 key Fob. This key Fob was used between 2010 and 2019 and takes just one of these CR 2032 batteries. You can change this yourself at home. It's really simple. All you'll need is one of these batteries which you can get online.

And I will put a link in the description for you to get it on Amazon for just a couple of bucks. And then we will just need a flathead screwdriver. So let's jump right into it. If we come down to where the keyring is, if you follow the seam down until we come to this little indentation here, there's that corner right there. That's where we're going to put our flathead screwdriver.

Just going to come into that corner, wiggling a little bit and applying pressure until it slides in. And then we can twist just like that. And you can see now we've started to open it up. You can just pull it apart with your fingers.

And now we just remove the buttons with the circuit board under it and lift the battery out just like that. Here we go. CR 2032. Make sure you get your new one and it goes positive side down. And then all we do is click it into place and reassemble the device.

The batteries on top. I mean the buttons on top of the battery. And this part just clicks back on and that's really all it takes. Super simple. I hope you found this video helpful.
