In my experience, they are not common in many businesses either.
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.
In American business over the past decade, I've experienced an order of magnitude more RFID-detector door locks than keypad door locks. Get your badge/wallet/purse/backpack within a few inches of the detector and you are in.
That is definitely the trend, because it allows security to give each authorized person a unique access credential, which in turn allows access to be selectively granted or revoked. When I worked in secure environments keypad locks were a pain in the ass, because every time someone's access to an area was revoked the code had to be changed.
Yeah, but that requires giving the locks brains, at which point you might was well just embed an RFID tag in everyone's badge. We had some areas that required both a badge swipe and a PIN.
