Can't open door...Help

Today was the day!! After almost a month of soaking, pushing, pulling, playing with the internal mechanism, I was just going to cut things off inside when I noticed the door looked like it had moved out a mm or two. Pushing from inside and hitting with my hands eventually popped the door open. The mechanism that catches the latch was what was all rusted. I worked it loose with penetrating oil and now the door opens and closes well. Thanks for all the advice!
