Well I didn’t sign my original lease for that building 20 years before the switch so if the traditional re-keying process had become more expensive I assume they would have simply updated their lease terms.

Your list of vaguely plausible what-if scenarios is exactly what I’m talking about. Neither of us has any idea what the true costs are, but for some reason the tech makes us more open to accepting what is at the end of the day an erosion of tenant rights and services.
