Why is my garage door not responding to the remote?

Your garage door not responding to remote can be due to several common causes related to remote itself, opener settings, and interference that prevent signal from reaching opener. First, check remote battery, as dead or weak battery is most common cause, causing reduced range or no response, so replace battery, typically coin cell or AAA, costing few dollars. Remote may have lost programming due to power outage, pressing Learn button too long erasing memory, or logic board reset, so reprogram remote by pressing Learn button on opener motor unit and pressing remote button within 30 seconds until opener light blinks. Check if wall console is in lock mode, as many LiftMaster and Chamberlain wall consoles have lock button that disables remotes for security, indicated by blinking light on console, so press and hold lock button for 5 to 10 seconds to unlock. 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, coiled, or not hanging straight, reducing range, so ensure it hangs down straight. Remote may be damaged from dropping or water exposure, causing circuit board failure, requiring replacement costing 30 to 60 dollars. Distance too far or obstruction like metal door can reduce range. If multiple remotes fail, logic board receiver may have failed and needs replacement costing 150 to 300 dollars.
