When it comes to smart locks, the goal is “Star Trek,” right? You should be able to walk up to your door and, swish!, it opens to greet you.
When I was a kid, “Star Trek” doors were amazing technology, but not too many years later, even the run-down supermarket in my hometown had automatic doors that opened when you approached them. Still, the dream lives on for the home. Most homes aren’t plausibly designed to have pocket doors that slide out of the way (and I have to think it wouldn’t be up to code), or even automatically swing open.
Okay, then, a dream downgraded: When it comes to smart locks, the goal is sort of “Star Trek,” in the sense that I’d like my door to unlock itself as I approach.
A few generations into this technology, we’ve bought and reviewed a bunch of smart locks, but the ultimate dream has not been fulfilled. Bluetooth-based locks can sort of do the trick, but since Bluetooth is a non-directional technology, there were all sorts of tricks (use geotagging, wait for the phone in question to leave the area, then enable lock-on-view) to make it happen. And it wasn’t very reliable.
Next came NFC locks, which work remarkably well but require you to press your phone or watch up against the lock. It works—I never carry a key for my house anymore, because my Apple Watch is my key—but it’s not exactly the Star Trek dream.
