Your garage door not responding to remotes and keypad but working with wall button indicates issue with remote programming, radio frequency, or lock mode rather than opener power or mechanical failure. First, check if wall console is in lock mode, as many LiftMaster and Chamberlain wall consoles have lock button that disables remotes and keypad for security, indicated by blinking light on console, so press and hold lock button for 5 to 10 seconds until light stops blinking to unlock and restore remote function. Remote batteries may be dead, causing weak signal, so replace batteries in remotes and keypad, which typically use coin cell or AA batteries costing few dollars. Remotes may have lost programming due to power outage or board reset, so reprogram by pressing Learn button on opener motor unit and pressing remote button within 30 seconds, and for keypad, press Learn button and enter PIN on keypad. Radio frequency interference from LED light bulbs installed in opener that are not garage door opener rated can block remote signals, as some LEDs emit interference, so replace with approved bulbs or remove bulbs to test. Antenna wire on opener motor unit that hangs down may be damaged or not hanging, reducing range, so ensure it hangs down straight. If remotes still fail after reprogramming and battery replacement, logic board's receiver may have failed and needs replacement costing 150 to 300 dollars. Keypad may have worn buttons that need replacement costing 30 to 60 dollars.
