My entry door lock would not open on September 2nd on our Class A, 2012 Serrano 34M. We had a locksmith crawl into a window to try and open it by removing the back plate (suggested by TriMark). He was not able to do this, the screen door was in the way, and I did not want him to damage the door. I ordered a new lock, apparently TriMark replaced the lock with an improved lock. They must have been aware of the problems with this lock. I agree, it should have been on a recall, it does create a safety hazard. Now we have to find out how to remove the old lock. We were fortunate that no one was trapped inside the Coach.
