Commercial work is priced differently from residential and quoting it over the phone is genuinely hard. Fire-rated doors, panic hardware and door closers carry code requirements, and the work has to satisfy an inspector rather than only the person paying.
A master key system is a design job before it is a hardware job. Getting the hierarchy right — who opens what, and what happens when one key goes missing — is most of the value, and a shop that produces a keying schedule you can read is doing it properly.
Even here the call-out is knowable. The site survey may be free or charged, and it is fair to ask which before booking.
