Keypad will not operate the door but remotes and wall button work.

Safety first: Use only Chamberlain-compatible keypads. Do not drill into live wiring when mounting.

Steps to fix:

• Replace keypad battery: Open the keypad and install a new battery (commonly 9V or coin cell, depending on model).
• Reprogram keypad: Follow the Chamberlain instructions to program the keypad PIN using the opener’s LEARN button.
• Check keypad location: Ensure it is within range of the opener and not shielded by metal siding.
• Replace keypad: If keys do not respond or the unit shows signs of water damage, replace the keypad.
