The trespassing dialog getting stuck is on the Miss in Action bugs list reload and go there only in the day so you don't end up trespass, or on a PC check the page for the console command to reset the quest (not the safest command though).

The door being locked can be caused by leaving the quest stages active for too long, like if you agreed to meet her then left to adventure for a while instead of following her.
