The remote stopped opening the garage door

Who they are

Marisol works from home and runs most errands by car, so the garage is the front door for her household.

Their home and door

An attached two-car garage with a LiftMaster opener, two visor remotes and a keypad by the door.

What went wrong

One of the remotes stopped working. The other still worked some days and not others, and only from close up.

What they searched

• “garage door opener not working”
• “liftmaster learn button location”
• “garage door won't open”

What they learned

• Try the wall button first. If the door moves, the opener is fine and the problem is the remote or its signal. Source: Your garage door remote stopped working
• Many remotes run on a 3V CR2032 coin cell, and a weak battery is a common cause of poor range. Source: Your garage door remote stopped working
• On LiftMaster and Chamberlain openers you press and release the Learn button, then press and hold the remote button within 30 seconds. Miss the window and you wait for the Learn light to go out, then start again. Source: How to program a garage door opener remote
