Safety: Garage doors are heavy and spring/cable systems can be under significant tension. Do not loosen or disassemble high-tension hardware unless you are qualified to do so.
Start With Basic Checks
Battery condition, correct code entry, and whether other controls still operate the door can help narrow down the problem.
Programming and Compatibility
Keypads must be compatible with the opener system and may need to be paired or reprogrammed after power loss or equipment changes.
When the Opener Is the Real Problem
If the wall station, remote, and keypad all fail, the problem may be broader than the keypad itself.
