Concord/express master code?

Is there a way to change master code in a concord or express panel without knowing the current master code? From my understanding is a upload has to be sent to monitoring station to retrieve it. Brother moved in new house in which builder contracted burglar alarm installed but he can't figure out what the code is. Haven't seen system yet but I can figure out installer code or default it but wanted to weigh out all options. Thanks guys or gals.

You can use the downloader software to change the code; otherwise, you have to clear/default the system and start from scratch.
