Honeywell 5834-4: Put Fob in High Security Mode

The Honeywell 5834 is a 4-button key fob generally used to remote arm and disarm your home security system. In this video we will show you detailed instructions on how to program the key fob to the Honeywell L5210 control panel.

The key fob has 4 buttons that can be programmed to 8 different functions, utilizing single and double key presses. Each button, or combination of two button simultaneous presses can be programmed in to the system. Follow the video to learn how.

As the video will discuss in detail, out of the box the key fob is ready to be installed. Each key press will require a 3-second press and hold. To test the battery out of the box, press any button for 3 seconds and you will see the LED light illuminate.

The flashing Led will vary between red and green. When it flashes red it means the key fob is in high security mode. Green flashing means low security mode. Honeywell has started shipping all key fobs defaulted with high security mode.

If you have an older version, or other factor that makes the LED light flash green, you need to put the key fob in high security mode. This two part video will discuss the method to do that. Follow along with your key fob to ensure you are using the high security mode.

On your key fob you will have four buttons. These will be labelled as keys A, B, C and D from top left to top right and bottom left to bottom right. You will need to simultaneously press keys A, C and D. Follow the video for reference.

Press and hold all three buttons for five full seconds. Once five seconds have elapsed, release the keys. Your key fob will now be in high security mode. The video will show you how to test to ensure this has happened.

Press any key on the key fob and watch the LED light flash. If it now flashes red, you are in high security mode. However, if it still flashes green, you are in low security mode and need to start the process over again.

Follow along with the video if you have any issues switching your Honeywell 5834 key fob from low security mode to high security mode.
