In this video, Jorge from Alarm Grid shows you how to find the Serial Number for a Honeywell Key Fob. The Serial Number for one of these devices will be found on a white sticker on the back of the fob. You can also find the Serial Number by auto-enrolling the device with a compatible security panel.

The Serial Number for a Honeywell Key Fob is used for enrolling the device with a panel. It is recommended that you auto-enroll the sensor to ensure successful communication. If you manually enter the Serial Number for enrollment, you might make a mistake, and then the sensor wouldn't work with the system. Auto-enrollment eliminates this possibility. Once you auto-enroll the sensor, the Serial Number will be displayed on the panel. This is a very easy method to figure out the Serial Number if the sticker on the back is missing.

When setting up a key fob for use with a Honeywell System, you will need to set the functions for the different buttons or inputs. Most users will want their key fob to be able to disarm, arm away, arm stay, and possibly trigger an emergency panic. These are all functions that you can set up for a key fob on a Honeywell System. Many key fobs also support dual-button presses. This means that if you press and hold two (2) buttons on the fob at the same time, then a different function will be performed. There are many four-button key fobs that can be set up to perform eight (8) functions in this way.

Remember that you must choose a key fob that communicates at a wireless frequency that is compatible with your panel. Most Honeywell Key Fobs use the 345 MHz frequency that is commonly supported by Honeywell Alarm Panels. If your system supports a different wireless frequency, then you will need to use key fobs from a different manufacturer. The only Honeywell Key Fob that doesn't use the 345 MHz frequency is the Honeywell SiXFOB, but that only works with the Honeywell Lyric Controller.

Note: You must associate a key fob with a user code for logging purposes. This way, when the fob is used, the event log, the monitoring station, and Total Connect 2.0, if used, will get information that the user associated with that fob armed or disarmed. The fob doesn't actually use or transmit the 4-digit code for the user it is associated with.


[ALARM GRID SOUND INTRO] Hi, DIYers. I'm Jorge from Alarm Grid. Today, I want to be going over how to get the serial number of your Honeywell key fob. Now first of all, what is a key fob? So the key fobs are these devices here. Usually, you see these linked into your car keys, your house keys. And you use these to arm and disarm your security system. Today, I'm going to be showing you guys how to arm and disarm and experimenting with the Honeywell Lyric system. So first of all, there is a whole bunch of different manufacturers of key fobs. Today, we're touching on just Honeywell's. And normally, whenever you guys get the key fob, whether you're actually buying it brand new or being passed down to you from a house that you're moving into that had an existing system, most key fobs will actually have the serial number on a sticker on the back. If you look at this 5834, you should see the sticker on the back. This is a normal 345 megahertz frequency Honeywell key fob. And you will see that it starts with one letter and seven numbers following after that. The next device that I have is the SiX fob. If you look at the back of the SiX fob, it also has a sticker. It's 16 hexadecimal. So it has different letters and different numbers. And if you look at the back, you'll see the sticker. That'll be the easiest way to find the serial number on most of these sensors. Now most of you guys may have gotten sensors where the sticker was already peeled off. Well, if you guys want another easy way of finding the serial number on these key fobs, would be-- there's little screws on the back. There's one right here. And then there's also one on the 5834-4. | you guys have a small little screwdriver, you can unscrew that. And then if you guys take a look at the back cover, the same sticker that you guys saw on the back of the main unit, the big sticker, there will actually be a smaller sticker on the inside and smaller writing that has a serial number as well. Now what happens if both of those stickers are gone? If both of those stickers are missing? The only other option at this point would be to auto enroll them into your panel. Today, I'll be demonstrating it within a Lyric system. But if you have an L7000, if you have an L5210, L5100, any Honeywell system that has a wireless receiver, you should be able to auto enroll these key fobs. So today, I'm going to show you guys how to auto enroll both of these key fobs into a Lyric system. So that way, you can get the serial number. We're first going to go ahead to make our way into programming. So for programming, you will need the installer code. Mine is defaulted at 4112. So I hit Security. I'm going to make my way over to Tools. And like I said, mine is defaulted at 4112. That should take me into this programming screen. If you entered in your installer code, which yours obviously as well maybe different. Your company may have changed it. But if you're entering the code and you're not taking to this screen where you have a programming option on your panel, then you didn't use the correct code. All right, so make sure you have the installer code. After you enter in the installer code, you hit program. Now normally, when we're adding in wireless devices, we go to Zones. But today, key fob is actually have their own section. So we're going to go to keys. When we go to keys, we're going to add new. Now when we add new, we hit Serial number. We to put the panel into a listening mode. And for the 5834, it's actually pretty easy. I just have to press one button for two seconds, the panel beeps. Have to do this total of three times. So that was my first one. My second one will populate the serial number. And then my third one will lock it in. Now I have my serial number, 0010488. If we look back at the back of the 5834-4, you'll see that the serial number says A0010488. The number-- Oh, I'm sorry. The letter will not come up on the serial number screen for a normal 5834 device. If you guys are using a SiX fob, which is the one that only works on the Lyric that's fully encrypted in hexadecimal, those letters will show up. And I'll show you that in a second. So now that we've auto populated the serial number, you can go ahead and match them up. 0010488. So they match. Perfect I need to give it a user code. If you don't give it a user, it will not allow you to save. After I give it a user, this key fob is now set to the master user. Whenever I arm disarm, it will be using the master code to arm and disarm the system. I'm going to hit Save. I'm going to go again to add new. And now I'm going to go Serial number. And now I'm going to show you guys learning in the SiX fob. SiX fob is a little more difficult. You actually have to press the top two buttons instead of just any button like the 5834. But on the SiX fob, specifically, you have the press the top two. So a little checkmark with the shield and the shield with the line running across it. I'm going to press and hold. The light started blinking. I'm going to go ahead and release it. And usually, it will auto populate. Sometimes, if you do close, it does cause an issue. I'm going to back away a little bit. The lights will start blinking back and forth between each one. And then since the panel's in listening mode, it should pick up on the SiX signal. Now again, just to confirm, these letters are actually pretty skinny on this one. I'm sorry, pretty hard to read. But zero, zero, delta, zero, two, delta, foxtrot, foxtrot, foxtrot, echo, foxtrot, alpha, three, bravo, foxtrot, nine. If you can see on the little sticker there in the previous image when we zoomed in onto the back, you'll see that the bravo will sometimes looks like an eight when you guys are looking at these stickers printed on Honeywell devices. So make sure that you guys distinguish what an eight and what a B as in bravo looks like. But basically, it auto populated. That's also a benefit of auto enrolling. You don't make mistakes like that. It actually picks up on this signal on its own. Populates the serial number on its own. I'm just going to go ahead and hit done. It auto populates again all the arm, way disarm, arm stay, puts them into their own fields. The one important thing when you guys are auto enrolling in fobs, is you have to keep in mind, each fob takes up pretty much three to four zones. You can also do double zone where like some of these fobs can take up eight zones if you do plan on doing two but presses. So if you press the two buttons at the same time, it does a different action. So there's a lot of different things you could do with these fobs, but they do take up multiple zones. Each button is a different zone. So that's something to keep in mind. And again, if you don't give a user and you try to hit Save, the panel will say, missing serial number or user. It's not the serial number we're missing, we have that. So it's just missing the user. Again, I'm just going to leave it as master. I'll hit Save. I'll hit the back arrow key. We've now auto populated. We've gotten the serial number of the key fobs. If you want to confirm that they actually work, I can go ahead and arm away. I can disarm with a SiX fob. I can arm stay with the SiX fob. And I can disarm with the Honeywell key fob. Remember, both of these key fobs, right now, they're using the master user code to arm and disarm. So they're always sending that master user code down to the panel. So that's pretty much the easiest way to find serial numbers on the key fobs. You either have a sticker on the back, you have the sticker on the inside, you just need a little screwdriver to remove that small screw, pull it away, or you can auto populate them the same way we just did when we programmed these key fobs pretty quickly into the Lyric system.
