I don’t think the card method will work on the dead bolts on my doors. I used to be pretty decent with a lock pick. Many years ago I worked in an area that was publicly owned open range but some of the nearby locals would put locks on the gates to keep trouble makers away. I preferred to pick the locks when I could instead of cutting them. Unfortunately I lost my picks somewhere along the way and haven’t found a new set I like. I have a spare key basically built into an exterior wall of the house that I could get into if I ever lost my key. Good luck to the criminal trying to find it and get it out without a neighbor noticing. It would be much easier for them to just break a window.
