Someone cited that they did have a Simplisafe alarm system. There is a wedding portrait (attached) that shows a keypad.Yes and also surprising the house didn’t have an alarm system. Or if so, it wasn’t on. Especially given the neighborhood (some bad areas and break ins close by) and 2 small children.
Residential doors are decorative and for privacy and can be kicked in and locks broken right off the wood frame. (see this in domestics, wife runs into BR, locks door, drunk husband shoulder checks door brakes it off the frame in 3 seconds). I don't know of anyone who locks their BR door when they sleep, usually that's for company or when you're changing.
