In this video, Jarrett from Alarm Grid shows you how to change the battery for a Honeywell 5834-4 Key Fob. The Honeywell 5834-4 is a four (4) button key fob.


Hey, DIYers, Jarrett here from Alarm Grid. Today we're going to be going over how you would change the battery on a Honeywell 5834-4 key fob. Now, these key fobs, they do use, or they come with a Panasonic 3-volt 2032 battery. And these batteries are meant to last, or they're expected to last about three to five years. Obviously, depending on its use. If you're using these key fobs a lot, then you could go ahead and drain the battery quite a bit. But if these are only being used seldomly, here and there, about three to five years is expected. You'll get a lot of good use out of them. Now, these batteries, they are the little coin cell batteries, the very thin ones. Very easy to install if you ever needed to do so. So this video should be able to help you out with that and take you step by step. We'll go over that in a little bit. Now, just to give you a little bit of info on this. If this battery does happen to drop to about 2.3 volts, then the key fob is going to go ahead and give you a low battery fault on the system. It's not going to immediately show a fault on the panel, but if you were to press any of the four buttons that you have programmed to be able to control the system, then it will go ahead and give you that fault and tell you that there is a low battery for that key fob. Now, whenever it does give you a low battery, though, it is going to show a fault on every zone that the key fob is programmed to. So for example, there's four buttons on a key fob. I have the Honeywell 5834-4 right here. And as you can see, there are four different buttons on this key fob. Now, in order for these buttons to work, they need to be programmed to a specific zone. So let's say you program this on zone 61, the disarm button on zone 62, zone 63, and zone 64. All right, if there is a low battery in this key fob and you press any of these four buttons, it's going to show fault on all four of those program zones to let you know that there is a low battery on this fob. Now, if you have alarm monitoring services, and there is a low battery from the fob, then also the central station will be able to receive those signals that there is a low battery. And if you haven't caught it yet, they can go ahead and give you a call, and let you know that there is a low battery on that device. Now, you can also get the notification through Total Connect 2.0 or if you do have those set up. You can set up specific notifications to let you know about low batteries and everything. Generally that is something that is generated as a notification. It's not something you normally have to set up within the application, but it is good to know. If you are using that platform, at least you'll be able to know whenever there is a low battery. Now, if you ever do want to go ahead and change the battery on the key fob, you can choose between a couple of them. But you want to make sure that they are the 2032 coin cell batteries, and you want to make sure are lithium. If they are alkaline batteries, they are going to die quick. They're not the ones that we recommend. You want to stick with lithium. Lithium are the ones that are going to last for a while. Now, the three different batteries that you can choose from, would be a Panasonic 3 volt CR32 battery, or CR2032 battery that I mentioned earlier. You have the Duracell DL2032 as well. And then there's one called the [? Sener-- ?] forgive me if I'm saying it wrong, but [? Sener ?] CR2032 battery. Those are the three batteries you can go ahead and use. But remember, lithium batteries. You want to keep that in mind. Now, if you ever do want to go ahead, or if you ever do need to swap out the battery on a key fob, or the 5834-4, it is very, very simple. As you can see, on the key fob, we have the four buttons in the front. If you look in the back, you actually have a screw that's holding it in place. And if you look on the side of the key fob, there is a little slit where you can put a small Phillips head screwdriver in there, or a pair of keys, or something to be able to pry it open. Now, as you can see, it is a little worn. We've opened this key fob a good amount of times. But if you get a new one, this is going to look not as torn up or anything. You don't have to worry about that. But if you do ever need to replace the battery, though, you always want to take out the screw first. You want to remove this, so you might want to get like a small Phillips head screwdriver or a small flathead screwdriver to be able to get this out. We're just going to remove the screw. It is a very small screw, so be careful not to drop it or lose it. If you do lose a screw, you may be able to find one or a replacement over at Home Depot or Lowe's. But to avoid anything like that, just please don't lose the screw. Now, if you do want to pop open the key fob, as I mentioned, you have the slit right here. So you just take a flathead screwdriver, and then you can normally just pop it open. Or you can go ahead and pry open with your fingers. Now, as you can see on the inside-- as you can see on the inside of the key fob, we have the circuit board along with the coin battery inside. Now, we have the CR2032 battery. Now, this isn't the Panasonic version, but this is a different 2032 battery. So as you can see on the inside of the key fob, we have the-- obviously, you see the circuit board. You have the battery right here. Now the one that we have installed, it actually is not a Panasonic 3 volt battery, but this is actually by Renata. This is another one that you could go ahead and use if you can find one, but the other three that I named off are the normal, typical ones that you can go ahead and purchase, and use with this key fob. So if you ever want to go ahead and remove it, you're going to take your flathead screwdriver, or even Phillips, but flathead is going to be a lot easier to use. And if you look at the top, you have a golden little lip right here. A golden clip. And this is where you want to have your flathead screwdriver. You basically want to put your screwdriver underneath this little area and just pop the battery out. That's it. Just pops out. And you have the area where you go ahead and replace the battery. Now, when you are replacing the battery, though, and this goes for any devices, really, you want to wait at least a minute before you put in the new battery. This lets the device reset, lets it be able to tell that there is a new battery being installed. If you just take one out, put it in and close it up, in some occasions, it's not going to recognize a new battery. So you just want to wait that minute and give it a little bit of time. Now, when you are getting, or when you're putting in a new battery, you want to make sure that the positive side is up. Positive is going to have this little plus sign right at the top of the battery. And you want to make sure that it's facing upwards on the circuit board. So where you want to start is-- in the same area that we popped out the battery, you want to insert the battery underneath that little golden clip, and then you push it down. So here, you're going to go ahead and put it in there in the golden clip, and then you're just going to pop it down, and then you're going to hear a click. It is basically in place at this point. If I were to try to move it, it's not going anywhere. If you do need to take it back out, you obviously know where to start. Just go underneath that clip. Push it out. Now, whenever you do put that back in, you're just going to go ahead and take your cover, or your back plate, and just close it right back in place. Grab a screw, and then just obviously screw that in. Make sure it's nice and secure. Now that you have a new battery installed, to go ahead and clear the fault on the panel that you had this programmed into, just hold down the Disarm button twice. You're going to disarm that system twice with this key fob, and it's going to go ahead and clear those faults that you had pulled up on the system, or that were showing up on the system. All right, so just one general note real quick so that you are aware of it. This is very important for the key fobs. But if that-- remember how I said when your key fob goes to about 2.3 volts, it's going to show that low battery. Now, you have about 30 days to go ahead and replace that battery before the key fob is completely dead. If that battery drops, or goes below 2 volts, then the key fob is it going to be dead at that point, and you will need to replace that battery. So if you ever see that low battery, you have about 30 days. Gives you a little bit time to go ahead and do it. You can pick up one of those 2032 batteries at Home Depot, Lowe's, Walmart, Walgreen's, whichever is closest to you. It's very easy to find these batteries. And that concludes it on how you can go ahead and change the battery on a Honeywell 5834-4 key fob.
