In this video, Joe from Alarm Grid shows you how to put a Honeywell 5834-4 Key Fob into its high security mode. In high-security mode, the 5834-4 operates as a bi-directional encrypted device. Only the Honeywell LYNX Touch Panels and the Honeywell VISTA Systems can support the 5834-4 fob in its high security mode.

There are two modes for the Honeywell 5834-4. There is a low-security mode and a high-security mode. When the key fob is in its low-security mode, it just sends one-way, unidirectional signals. In low security mode, the device can be programmed to multiple panels if desired. For many applications, low-security mode is fine. The only thing you really need to worry about is that the signals are not secure and can be easily intercepted using some certain hardware. This is sometimes done by really savvy intruders.

But high-security mode uses encrypted signals to prevent the interception of its wireless signals. The downside though is that the sensor is more difficult to program. Additionally, you will not be able to use the Honeywell 5834-4 Key Fob with multiple panels while it is in its high-security mode. You can easily distinguish between the high-security and low-security modes of the 5834-4 based on the LED light color. High-security mode has a red LED light, while low-security mode has a green LED light.

To toggle between security modes, you need to make very specific button inputs. Low-security mode is entered by pressing and holding the disarm, arm stay and asterisk buttons. High-security mode is entered by pressing and holding the arm away, arm stay, and asterisk buttons. You will probably need to use both hands to successfully press and hold all three of the designated buttons. The buttons must be pressed and held for five (5) full seconds to successfully toggle between the two different modes.




Hi, DIY-ers. Joe here from AlarmGrid. And today, we're going to talk about how to switch our 5834-4 for key fob from low security mode to high security mode. Knowing the difference between low and high security on this key fob is going to save you some trouble and let you get some more features out of this particular unit. The 5864 is part of Honeywell's 5800 line of sensors, which is wide, varied, and has been around for a long time. It's really a good key fob for what it does. If not, a bit basic in its features. The two operating modes that this key fob has is low security and high security. When the 5834 is in low security mode, it's going to send the same string of characters every time that it transmits to the system. So that means that every time you press the button, it's going to send the same command to the system. If somebody's on location with a sniffing device, what this would do is it would pick up or sniff the air to get the communication data. And if found out what that was, they could potentially spoof that command and send it from their own device, tricking your system, and unlocking it for them. You don't this to happen. When you put the key fob into high security mode, it's not changing any communication on the key fob. It's still saying, you need directional. What's happening though is that when we put it in a high security mode, we have to sync it with the alarm system. When we sync it with the system, now the system is going to know what commands the fob is going to be sending going forward. A fob itself will be transmitting different commands every time it communicates with the system and this adds extra security because when somebody sniffs the air and gets the communication data from the fob, they won't be able to spoof it because they won't know what the next string of data should be that's sending from the fob to the system in this mode. So it's a way of providing high security for your key fob and the system. It adds an extra layer and it should prevent anything like that from happening as far as spoofing a regular command from a key fob. It's really easy to see what mode the key fob is currently set into. If it's in low security mode, it's going to flash green. And if it's in a high security mode, it's going to flash red. Now, the flashes on this key fob are a little on the light side so I don't know if you can see this, but it is currently in a low security mode. When I switch it to high security mode, you should see this LED turn red. So let's do that now. To switch the key fob into high security mode, all you have to do is hold the top-left, bottom-left, and bottom-right buttons at the same time until that light turns red. Give it a shot. There you go. That red light tells us that we're in high security mode. And if I press a button, it's flashing red. To switch it back to low security mode is just as easy. I pressed the bottom-right-- bottom-left, bottom-right, and the top-right. And what will happen is the light will turn green, telling me that I'm back into low security mode.
