How do I change a Honeywell 5834-4 battery?

The Honeywell 5834-4 four button security key fob is powered by a replaceable Panasonic 3V CR2032 lithium battery (already inside) that is expected to last 3-5 years. Once the battery voltage drops to 2.3 volts, a low battery message will be displayed on your keypad. This will happen the next time any button is pressed, and a low battery condition will display for every button zone programmed for the 5834-4. For instance, if your 5834-4 is programmed on zones 61, 62, 63, and 64 then all four of these zones will display low battery upon the next press of any of the four fob buttons.

If you have alarm monitoring service, the low battery message should also be transmitted to the central station so that you can be notified of the problem. Once this happens, you will typically have about thirty days to replace the battery before it drops below 2V and the fob stops working completely. If your 5834-4 is indicating a low battery, please follow these steps to replace the battery.

  1. Open the device. Open the back side of the key fob by using a small Philips head screw driver to remove the screw.
  2. Remove old battery. Once opened, slide a small flat head screw driver underneath the battery on the gold tab side and pop the battery out. IMPORTANT: After removing the old battery, wait one full minute before installing a new battery.
  3. Insert new battery. Next, you will need to slide the new battery (+ side up) underneath the gold tab. Then firmly press down on the opposite side. The new battery should click into place.
  4. Reassemble the fob. After double checking that the battery is positive side up and firmly positioned, and that the back cover is popped back into place, you may screw the cover back down.



With the new 3V battery installed, you should be able to press the disarm button twice. This should send a disarm command to the panel as well as clear the low battery messages from the display. Be sure to use only replacement batteries recommended by the manufacturer. In this case, use only Panasonic CR2032, Duracell DL2032, or SENER CR2032 Lithium batteries.
