The little button with a padlock on the wall control is a "vacation" lockout feature that disables the remotes. There should be a small LED on the wall control that is always on steady. When the padlock button is pressed and released the LED should be constantly blinking (indicating the vacation lockout mode is active) and your remotes should be disabled. The wall control will still operate the door. Pushing the padlock button again should make the LED stop blinking and restore the door to normal operation.

Will the remotes work in the garage? If yes but not outside with the door closed you might have radio interferace with your remotes. You might have to chage to a your reciever and remotes to a different brand (frequency). Sometimes it is less trouble to change out the operator. Chamerlain changed frequency from 390 (old) to 315 (new).

wow nutone is a dying bred but what you have is a outside radio meaning that its a sear set up to your opener you should be able to take your remote down to sears and they can match it up for you.

To erase the memory of the opener so that your old remote will no longer work you need to locate the smart/learn button on the rear of the motor unit. Press and hold this button for 6 seconds. No remotes will now work.
To program the new remote when you get it, hold the button down on the remote and then press and immediately release the smart/learn button.
Call any local door opener repair company from the yellow pages and you should be able to buy a remote from them.

look for a smashed wire between the motor unit and the wall button.
If the wire is smashed the insulation becomes so thin that power will leak thru the insulation.
Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.
The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone’s purse that gets the button pushed by other stuff in the purse.
The test is to disconnect the push button wires at the power unit. If the interference stops you have located the problem. If you reconnect the wires and disconnect the wire at the wall button this will tell you if the problem is the wire or the button.
HOPE THIS HELPS
