I have only been hosting for 9 month and have had a problem with a guest getting in to the house recently. I have a combination lock on the front door and the door knob lock is not to be used. My cleaning company had a new cleaner and when they left they locked the door so the guests could not open the door. I had to drive over and I live 20 miles away to let them in. Has anyone had this or a similar problem and what can be done to prevent it. I have a garage entrance but the guest do not have an opener for it.
