Your garage door opener keypad isn't working due to several common causes related to battery, programming, lock mode, interference, or physical damage that prevent PIN entry from opening door. The most common cause is dead battery, as wireless keypads use 9-volt, AAA, or coin cell battery that lasts 1 to 3 years, and when battery dies, keypad lights dim or don't light and door won't open with PIN, so replace battery with same type costing 3 to 10 dollars. Keypad may have lost programming due to power outage, pressing Learn button too long erasing memory, or logic board reset, requiring reprogramming by pressing Learn button on opener motor unit and entering PIN on keypad within 30 seconds and pressing Enter. Wall console may be in lock mode that disables keypads and remotes, indicated by blinking light on console, so press and hold lock button for 5 to 10 seconds to unlock and restore keypad function. Radio interference from LED bulbs in opener that are not opener-rated can block keypad signal, so replace with approved bulbs. Keypad buttons worn after years of use cause poor contact, requiring hard press, indicating button failure needing keypad replacement costing 30 to 60 dollars. Water intrusion from rain if keypad seal fails can corrode circuit board causing failure. Check if keypad is too far from opener or antenna wire damaged reducing range. Try entering PIN close to garage to test range. If keypad still fails after battery and reprogramming, logic board receiver may have failed.
