help, shut out of coach...

[Rose Mary]

Hi all,
hoping someone can tell me if the hinge rod can be removed from the
door?
Somehow the door won't open, don't know if the door knob got tangled up
with the screen door slide inside or what. My niece took some stuff out
to the coach last night and now I can't get in.
If it got locked somehow when she came out don't know, the keys are
inside the coach...
Of course all the window latches work great and are closed as I had the
air conditioner on.....except the door window which the top easily
slides down.
So, wondering if the hinge pin is one long rod or two as top and bottom
appear to be rounded out.
Any suggestions?
thanks
