I'm having second thoughts on having the inside part of door lock keyed. It just seemed like a good idea at the time. If someone broke in some other way, window, etc. they wouldn't be able to just open the door and make out with the stuff. That's my reasoning. There's no window in the door that would allow them to break and reach in to unlock it. I would have a key hidden somewhere nearby that I could access in case of an emergency. Or just throw a chair through the main living room window, or just open a window for that matter, and crawl out.

Or walk across the room and exit through the sliding doors.
Or kick a hole in the wall, and just exit through the wall. (Hoping there's no nails driven in through the outside that's now inline with my foot.)
