Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
...because the wall mount works but the remotes do not. My unit is very old and I don't see a little "padlock" button on the wall mount. How do I deactivate the lock feature? Thanks!
Does logic board on motor have a small pushbutton or dip slide switches? If pushbutton, push it for 10 seconds. let do. panel light stop blinking? Unit somehow got into lock mode, even though you do not have lock button. If this has stopped light from blinking, you now have to code remotes and or keypad back in. Push the little buton for 1 second and push a remote. Light bulbs on unit should blink. Take next remote (or keypad) and repeat this sequence for each one. Let me know. If you have safety beams, liftmaster should help you. w/o beams they will not support.
