On a late summer Sunday afternoon I was dog sitting my daughter and son-in-laws 5 month old puppy so they could have dinner out with friends. We were initially sitting out on the front porch; however decided to move to the back deck. I locked the front door as we came in and removed the dogs leash. Since it was quite warm out, I closed the storm door as the air conditioner was on.
After we had been on the deck for a few minutes I decided to go inside to turn on the dishwasher. I couldn't open the door. Initially, I thought that I was just not pulling hard enough, etc.; however that was not the case.
I could see that the lock lever was in the up position. After about 30 minutes trying to decide what to do, I went around to the front door just to see if maybe I just thought I locked the front door; it was locked. I go back to the deck and wait another 20 minutes or so to send a text to my daughter letting her know that we were ok, but locked out. She responded about 45 minutes later as her phone had been in her purse. She indicated that they would be on their way in a few minutes.
The dog started running around the deck (I call them zoomies) which he does from time to time, but this time, it lasted for a while. I remember thinking as it was getting dark, that my daughter would come home to a dark house (no lights on inside or out). That's about the time that the dog stopped running around and kept looking inside.
The lights are now on. This detail I did not remember until the next day, or otherwise I would have been frightened. When my daughter came home, she confirmed that the door was clearly locked. One has to put a little pressure on it to lock. We tried to re-create by going outside, pulling the door shut; and it never locked.
The house is new so I did speak to the building supervisor the next day. He said its impossible to lock the door from the outside; however he came over immediately and tried to recreate the lock from the outside and couldn't. Thank you for reading. Any insight would be appreciated.
