Next thing - no master code should, for obvious reasons, be the same between multiple installations. If the customer have a master code to open their lock, no one else needs to care.
Per,
I have no doubt we, basically, agree on this issue; however, I have never heard "master code" used for "code that differs between locations"

what you say is, basically "give every customer two access codes"

One "slightly tricky" form of an individual master code is some formula that derives the master code from the serial number of the unit.
