How To Replace the E39 BMW 5-Series (1995-2003) Key Fob Battery

Both the E39 and the E60 have the diamond shaped key fob with a rechargeable internal battery. Here’s my video from the 3-series which has the same fob. This is a more advanced replacement and requires a some soldering:

Alright. In this video, I'm going to show you how to replace the battery in this BMW diamond key that was used in the E46. This is for the 3- series from 1998 to 2005. BMW cars. So this is a fairly complex change, but I'm going to get right into it here.

So the first thing you need to do on this key is you need to separate it into two halves. So you'll notice around the edge here, there's kind of a line that separates this key Fob into two pieces . What you're first going to do is take a box cutter and score all the way around, cutting through and actually breaking through the plastic all the way around this key. And this may take some time.

This may take five minutes. This could take ten minutes. If you want to kind of do it carefully, try to keep the key as intact as possible. But the best key that I found to get some leverage was right here at the top. You can eventually cut through and then you can see the box cutter even going through there to start to get some separation between these two pieces.

So once you score all the way around, you'll be able to separate these two pieces here and get access to the circuit board and the battery that we'll need to replace. Now, the battery that you need here is a VL 2020. This is a rechargeable battery. Normally, when the key is in the ignition, this battery charges. But for whatever reason, if it dies and you need to replace it, this is what we're going to show you how to do.

So inside this part of the Fob here, there's a circuit board that you can remove. You can see there's kind of two points that connects here and you can just probably kind of tap it out like so you can't tap it out, maybe some small tweezers here, get that circuit board very delicately pull that out. Okay. So the circuit board here is what we're going to be working on. The key here is this battery that we want to replace.

There's two points that's attached to the board here. You can see these two points of solder here and here. These are called the legs of the battery. And these are where the battery actually attaches to the board. So to replace this battery, we need to get these desolder.

And then when we buy replacement, make sure that you buy one that has legs that are offset 90 degrees here and here, not that's offset 180 degrees, because then it won't match up with your circuit board. So I've got a soldering iron here and a little soldering vacuum. And what I'm going to do is just desolder these points here. And I just got this soldering iron for $19 on Amazon. And if you've never soldered anything before, don't worry.

This is actually not a bad little spot. To learn because there's not a whole lot you can screw up too much here. So what I'm just doing here is melting the solder and then suck it up. And I'm just going to melt some more here. Just decent amount and suck it up.

Okay. So we've got quite a bit removed there on that one. I'm going to do this other point here and see where we're at that's melted down nicely. A little more off here.

Okay.

So you can see all this solder that we've gotten off of here. And now this should allow us to easily pull off the VL 2020 rechargeable battery here from the circuit board. So let's see how we did. Excellent. Okay, so we've still got a little bit of solder there that we need to go.

So actually, this time I'm just going to melt it and see if I can let it drop through. There we go. Perfect. So, yeah, sometimes you can just have to suck it all away, but just melt it out. And there we've got the leg of the battery out on this one.

The second leg disappeared over the years. But that's okay. I think we'll still be able to attach it here, especially since we have a new battery. So new battery. Make sure that we've got leg here and a leg over here.

This one only has one. If you only have one, then work with what you got. So we're going to resolder this now. Attaching the battery there.

And the second point, the leg would actually go right in here. So I don't have a new battery. But we'd take the new one, make sure that the legs get in through those two points there.

I'm going to actually clear off some of this solder here to make a little more room here and get the legs in through there.

And then we are going to resolder once we have this actually attached here.

Okay. Then we'll take a little bit of solder and just solder on these points here.

Okay. And then the other leg over here like so. Okay, so now we've resoldered the new battery onto the board here and then we'll go ahead and just replace this back into its correct spot. Make sure the buttons here are going to the button side here. So flip this over and make sure that aligns back in there correctly.

All right. Snaps right in and then I'd apply some super glue here around the edges and then put the battery back together or the Fob back together. And if you superglue that, then you have a brand new working key Fob with a new VL 2020 battery on your 3- series for the E46.

Alright. So in this video, I'm going to show you how to replace the battery in a BMW 5- Series. Like 520i, 523i, 525i. For example, this was the key Fob used from 2007 to 2010 for the 5- series. Now, there's two different types of Fobs that you may have gotten.

Key remotes here, Comfort Access and then the Non- Comfort Access version. If you have the Non- Comfort Access version, the back end won't have this square outline that you see here in the Comfort Access key. So I'll show you how to replace that in another video. But to replace your 5- series battery with the Comfort Access, all I have to do is to press the button here to remove the valet key. And this will give you access to a small little hole right in the middle of the backing that pops off here.

What you can do is just take a small flat head screwdriver or even some nail Clippers and just kind of slowly pry into that gap right there. And that allow you to pop off this back here and give you access to the replacement battery that you need for your 5- series. To replace this, the battery is the CR 2032. Pop that out, grab a new one.

Just make sure the positive side is facing you, which is the side with the text on it here shows the battery type, pop that back in and that will kind of play a little bit. You can depress it and then pop the back on that snaps in and that's so that's how you replace the battery on your BMW 5- Series. If you have a model from 20 07, 20 08, 20 09, 20 10.

This is going to be a short little video on how to replace the battery on a BMW 5- Series. This is going to be for model year 2007 to 2010 for the BMW 5- Series. So that'd be like 520i, 525i, etc. So the first thing you need to do, you see your rectangular key Fob here. Make sure it matches this video.

If not, check out my channel for other key Fob. But when you turn it over, if you have the Non- Comfort Access version, which is what we're going to be changing here, this back will look like this. You won't see any kind of outline or cut out for kind of a square. This is the Comfort Access key allows you to unlock the car without having to press new buttons and such. That's a different battery.

And that's not what we're looking at here. But I'll link to that video. If you do have the Comfort Access key for your 5- Series, for the Non-Comfort Access key, you're going to have to pry apart this fob into two different pieces. So first thing I want to do is take a utility blade or box cutter and score around the middle here, take out the valet key here and just go ahead. And this may take five to ten minutes, but kind of carefully score around and start to try to pry apart this middle part if you can.

And as you do that, just be careful to just kind of cut and pry, cut and pry. And eventually you'll be able to kind of maybe get a small flat head screwdriver like this into break apart this key. Now you'll want some super glue at the end. Once we've changed the battery to put this all back together because it doesn't exactly clip back together. So once you've got that scored and separated, you get access to the internal part of the circuit board here.

And you can see these are some of the buttons on the board here. If we flip this over there's, what we are going to be changing. This is the VL 2023 volts battery. And one of the things you want to make sure that you get correct on this is the solder points are here and here. So when you buy a battery, make sure you don't get one that's offset 180 degrees, but you get one that's a 90 degree offset.

So to change this battery, if this battery has died, we're going to need to desolder these two points here and then put in a new VL 2020 battery. So if you've never done any soldering before, I'll link to a little Amazon kit here that I got. It was pretty straightforward. So what you need to do is this is Desoldering vacuum. So what I'm going to do is desolder these points here on these legs and you can see it started.

And then we'll suck up some of that solder and we'll just keep on that point there and suck it up. Okay. And then on the other point here we're just going to melt this solder down.

What we're doing here is just getting access to the legs. The legs are the connection points on the VL 2020 rechargeable battery. Okay, let's see how that looks here. So once we've desolder those two points we'll be able to remove this battery here and now we can grab a new VL 2020 battery and make sure we've got these two connection points here. So we take our new battery with these 90 deg offset legs here on this battery and reattach that through the two points on the circuit board here and then we just want to solder these together so take a little bit of solder and a soldering iron and I think I got this kit for like $19 on Amazon so it's nothing fancy but it will get the job done.

Just resolder that point there and that should do it. So now we've got the point resolder and we can now reassemble the key Fob here. And again, this is for the 5- series 2007 to 2010. This rectangular board here. All right.

This looks good. Battery resolder on there. Seems pretty solid so go ahead and put this back into place and at this point we probably want to get this on the correct direction here. Might want to get some super glue and kind of super glue around the edges here just to make sure that this key stays really secure because otherwise this doesn't quite snap into place once you've kind of remote even separated these two halves so a little bit of superglue there and boom, that's it. So that's how you replace the VL 2020 rechargeable battery again for a Non-Comfort access.

All right. This is a quick video on how to change the key Fob battery or replace it in a BMW 5- Series. This is for some more newer models here. It's going to be 5- Series. And this is for years 2017 to present.

So if you don't have the display key, this is what you need to do. So here's how you do it. First thing you want to do is look on the side here to press the valet key, remove this, set that aside, and you'll notice on the back here there's a small indentation we can place like a small flat head screwdriver, and there's a small indentation there. And if you kind of wiggle your way in there, you'll be able to pop this back right off and get access into the battery that you need to replace. So the battery here is a CR 2032.

And to replace this, just pop this out. There's kind of some kind of pops out here. There's some base here to attach the battery and some attachments up here. So grab a new CR 2032, pop that back in as a 3 volt, and just make sure the positive side is facing up here, which is where the etching is on the battery. And go ahead and pop this backing back on and make sure that there's kind of these two edges down here on the curvy side.

Put those in first. It makes getting the rest of the back popped in a lot easier. And then replace the valet key. And boom, you're all set. That's how you replace the battery on BMW the 5- Series.

That's like 520i , 530e, 530i etc. from 2007 to present.
