If you have more than one remote and they all work but when you try to program the keypad it causes the remotes to quit working then your keypad is bad.

Liftmaster 973LM. Remote opener does not work. Replaced battery - still does not work. Original owner left no manuals. Works with outside pad and inside button.


ONCE YOU REPLACE THE BATTERY YOU NEED TO REPROGAM THE REMOTE.

WATCH THE LED NEXT TO THE PROGRAM BUTTON WHILE YOU PRESS THE BUTTON ON THE REMOTE IF IT FLASHES THE REMOTE IS SENDING A SIGNAL AND SHOULD WORK.

IF IT DOESN'T FLASH THE REMOTE BATTERY MAY BE IN BACKWARDS OR THE REMOTE MAY BE BAD - IT IS NOT SENDING ANY SIGNAL AT ALL.

HOPE THIS HELPS

Outdoor keypad frequently doesnt work


IF REPLACING THE BATTERY DOESN'T DO IT YOU WILL NEED TO REPLACE THE KEYPAD.

NOTE: (IF YOU HAVE A ROLLING CODE SYSTEM) YOU WILL NEED TO REPROGRAM THE UNIT AFTER YOU CHANGE THE BATTERY.

HOPE THIS IS HELPFULL

Outside garage door key pad will not function in very cold weathe


Yes, that is an issue.  My suggestion is to replace the outside keyless with a wired keyless (Domino GD-1).  This will get your batteries inside so they can stay warm.
