I've never understood why keypad locks haven't been more widely adopted in the West - they're very common in South Korea (and probably many other Asian countries). Lockitron seems like a solution in search of a problem.
They have been adopted widely. In businesses. It's mostly a perception issue, where such locks are perceived as a product for a business.
That said, it's a lot more convenient to walk up to a door and have it unlock automatically because it detects your phone ... than to stand there and enter a code.
As for the convenience factor, it might be more convenient, but I don't think it's a lot more convenient to have Lockitron instead of a conventional keypad lock. Unless Lockitron can also automatically open/close the door for you, I just don't see the difference as being that great.
In any case, I think the real business opportunity lies in figuring out how to market keypad locks to a broader audience.
It may be a local issue, though, I'm not in the US, and shipping is usually not cheap.
I don't remember seeing them in Germany
But there are models that are made to go on an apartment door/main door.
However, they don't usually replace the whole lock, but are there for authorized people to go during business hours
Yeah, not really a replacement for Lockitron
