If the key fob is activated while the batteries are low, the LED will blink red for two seconds. No arming or disarming will occur. The key fob batteries need replacing.
When the system or key fob indicates a low battery condition, replace the two CR2025 batteries. (Panasonic CR2025, Duracell DLCR2025). Follow these steps to replace the batteries:
- Remove the top cover by inserting a coin in the slot located at the bottom of the key fob and turn it 90 degrees.
- Use a small Phillips head screwdriver to remove the screw located in the centre of the printed circuit board. (Keep hold of the screw.)
- Remove the printed circuit board.
- Remove the two depleted batteries and dispose of them as required by local laws.
- Insert the replacement CR 2025 batteries. The (+) side of the batteries should be facing down.
- Replace the printed circuit board with the side with the two large circles facing the batteries.
- Secure the printed circuit board by screwing it in place with the screw previously removed using a small Phillips head screwdriver.
- Snap the cover of the key fob transmitter over the base assembly.
- Verify that the key fob is working properly by pushing the buttons. You will see the red LED illuminate if the transmitter is working.
