Why doesnt work


The remote may have to be reprogrammed, also make shure the battery is new not just because it,s in a package but because of the freshness date , also check the contac points of the battery in the remote , sometimes they get battery acid on them and could damage it, stiny circuit board ..if all else fails you can purchase a new remote on ebay depending on your garage door opener brand model and frequency ! Hope this helps, Sincerely Glenn

I have a Lift-Master Security remote garage door opener. It has a new battery. Can it be reprogrammed or do I have to replace the remote?\r\nThank you for your assistance. Model number971LM. It will...


ANY TIME YOU CHANGE THE BATTERY IN A REMOTE IT NEEDS TO BE REPROGRAMED.

ON THE CIRCUIT BOARD YOU WILL FINS A SQUARE BUTTON.
PRESS AND RELEASE NOW HOLD DOWN THE BUTTON ON THE REMOTE FOR ABOUT 20 SECONDS. WHEN YOU PRESS THE REMOTE THE NEXT TIME THE DOOR SHOULD OPEN.

Keypad and remote will not open door


Did the remote and keypad work before you changed the battery? Changing the battery in the keypad should not affect the remote.
