The cell phone + supra lockbox approach could work. One would need to be a realtor though. Supra only sells through realtor associations.
Thanks for the info regarding the components.
I wonder if there'd actually be a market for this kind of thing.. i.e. One person unlocking access to physical keys in a lockbox at a remote location so that another person can gain access to something. It would be used in a temporary installation, not like ring.com installed at a front door of a house or remote access tech built into cars these days.
Another case of technology in search of a problem... :-(
We actually built something like this but for bikes. http://lockandgo.bike/index_en.html, it has data connection for remote lock/unlock and even gps to get the position. There was no market. We could pivot to this easily...
