I can see a smart lock being quite useful, though I don't trust any current implementations. I use my front door multiple times a day, have to unlock it first to go out then lock it up again. I can't let my girlfriend in without me being there. When it's cold or I have things in my hands, fishing my keys out of my pocket becomes downright difficult. Taking out the trash involves navigating three doors and two locks, while carrying garbage - I'd love to eliminate even just one of those. And if I could not bring my keys with me while running, I'd be happy. I grew up in a place where we never locked the house or cars. But the lock doesn't have to be super smart to fix these things, or at least most of them.
