Hi there, Can anyone tell me how to use the little round lock, we've turned it, pressed it, pressed little button on the knob, don't know if it's stuck in the runners, not my Camper it belongs to bro-in-law.
post a picture. Sometimes a spray into the crevices and gaps, then a rapid tapping on the button may release a stuck mechanism. Need more info to give proper advice
