Hello! We are new to this group and hope that someone can throw light on our problem door. We've had our wonderful 201 since Feb and the habitation door has never been easy. However today it just won't lock. We've tried everything from using the key, trying from inside, passing around with the mechanism. Has anyone else had this problem and if so what did you do to rectify it? Do you think Marquis need to get a new lock mechanism in before we take it to them? Looking forward to sharing tips n tricks with other Benimar ers, esp 201s.
