Garage Door Remote Not Working? 5-Minute Fix

In order of likelihood

• Replace the battery (CR2032 or 23A — check the back)
• Stand directly under the opener — if it works there, it's a range issue (replace antenna or move the opener)
• Re-program the remote: press the Learn button on the opener, then the remote button within 30 seconds
• LED bulbs near the opener can cause RF interference — swap for incandescent or 'garage-door safe' LEDs
• If nothing works and the wall button still works, the remote is dead
