I'm not even sure my front door even opens anymore. I enter and exit thru the garage, so I don't think I have used the front door in 2-3 years. I even have UPS and Fedex trained not to leave packages at my front door, since I never look or go up there. I usually throw away all the phone books, fliers, etc when I mowing the lawn and am around by the front door. Good thing they don't deliver much of that crap during the winter months. That reminds me I need to sign up on the no phonebook list they were just talking about on the news. https://www.yellowpagesoptout.com/
Edit: I just checked, the door does open and close, although it could use a bit of oil on the hinge, and it was locked.
