How to change the battery in a garage door remote
- If there's a screw on the back, loosen it until it spins freely.
- Pry the case open with the visor clip or a small flathead screwdriver.
- Push the old battery out toward the nearest edge and note which side faces up.
- Put the new battery in the same way (on most coin cells the + side faces up).
- Snap the case back together; don't overtighten the screw. Press a button: the LED should light.
Keypads: slide or unscrew the battery cover (usually on the bottom or behind the flip cover), swap the battery and refit the cover. Your PIN stays programmed.
How to replace a garage door opener backup battery
- Unplug the opener.
- Open the battery cover on the opener head (or the separate battery box) and unplug the battery leads.
- Fit the new battery and reconnect the leads, red to red, black to black.
- Close the cover and plug the opener back in. A new battery can take 24 to 48 hours to fully charge, so the warning beep or light may stay on for a while.
Keep coin cell batteries away from children. If one is swallowed, get medical help right away. New battery didn't fix the remote? See replacement remotes or the remote finder. Questions? Call 877-379-4947.
