If it is a TriMark you WILL get locked out. Once it starts getting sloppy the very next step is when the cheap pot metal they use on the inside breaks off and you either get locked in your RV or locked out.
Been there done that TWICE. Once with original equipment and the second time with a new replacement....which is NOT cheap. I had to bend the door frame back to get it out.
If it's a Trimark I understand they now make a steel replacement part for the one that breaks. I highly suggest you look it up and get it replaced ASAP. Can't tell you what a nightmare it is when that breaks and you can't get in or out when you are on the road camping. Good Luck!
