Great Read.
I see a ton of the GE Supra iBox Lockboxes. I hear they cost realtors a lot and they have no alternative. Perhaps for the VRBO or non-Realtor properties too.
This is a really stupid question, but will there be hybrid locks not for door/access but stuff we never thought could be locked in the old mechanical days? a pack of cigarettes? pill bottle? sleeve to a jacket? briefcase? mouse? baby child-proofing? an envelope?
