I've tried a few of these. Kevo, lockitron, and some RFID one from samsung (which was my favorite). The main problem for me, mentioned in the article, is that residential doors are often not well aligned. if you try to open the door while locked you can end up putting enough pressure on the deadbolt that the motor can't open it. Humans recognize this with mechanical locks and we automatically adjust.

The worst part of that, though, is when the smart lock tries to reset it self and try again. You end up standing there while it goes back and forth, and in the end it's a huge hassle.

Humans are good at adapting to new situations and dealing with ambiguity like misaligned doors. With my mechanical lock, I can get really good and really fast at opening it in all circumstances. but with the smart lock I'm subject to it's slow speed and inability to adapt to new situations. I can't make it go faster.

I'd rather doors be redesigned to be more like car doors.
