Keypad or key switch does not operate the Nice opener, but wall button and remotes work.

Safety first: Disconnect power before rewiring inputs.

• Check keypad batteries: Replace batteries in wireless keypads and re‑test.
• Verify wiring: For wired keypads or key switches, ensure the common and normally‑open contacts are wired to the correct START or OPEN/CLOSE terminals on the Nice board.
• Test device directly: At the board, short the two wires from the keypad/key switch. If the door moves, the device is faulty. If not, the wiring or board input is suspect.
• Input configuration: Some Nice boards allow assigning functions to inputs. Confirm the input used by the keypad is configured as a step‑by‑step or open/close command.
