Guardian opener remotes and keypad do not work, but wall button operates door normally.

Safety first: Keep clear of the door while testing remotes. Use a ladder safely when accessing the Learn button.

• Reprogram remotes: Press and release the Guardian “Learn” button. Within 30 seconds, press the remote button you want to program. Wait for confirmation (light flash or click).
• Reprogram keypad: Follow the keypad instructions to sync with the opener using the Learn button and a chosen PIN.
• Test multiple devices: If none of the remotes or keypad will program, the RF receiver on the logic board may be faulty.
• Replace logic board or add external receiver: Install a new Guardian logic board or an external universal receiver connected to the opener’s push-button terminals.
