The thing is, the definition of a great product is one that solves a user's need. While people may have problems with the internet-connected door locks they have now, I'm pretty confident their issue isn't with the deadbolt mechanism, which is as close to a solved problem as you can get.

The market for people who care that their door locking mechanism is as precise as a Swiss watch is so vanishingly small, it feels almost self-evident that there's not a viable business there.
