Masterkeying n. 1.
the planned destruction of security in exchange for convenience
Simply put; The most secure system uses a different key for
each lock, but this is not convenient. The most convenient
system uses the same key for every locks, but this option lacks
security. A well designed masterkey system finds the optimum
balance between security and convenience.
The most important step in masterkeying is planning ahead. It
is easy to 'paint yourself into a corner'; then all of your hard
work and expense may be compromised trying to extricate
yourself. First make a list of ALL of the doors and locks
involved. It is important to think ahead. Do you plan to
expand? Are you skipping over locks to save some money?
Include all of these locks in you master plan. -include all locks
you can think of then ask these questions:
Who needs access? (ask this question for each lock)
write this down -preferably in a spreadsheet
Do I need restricted / patented keys? (to prevent unwanted
duplication of keys)
this is always a good idea
How often will I be changing (rekeying) locks?
is there a frequent turnover of employees / tenants?
Gather this information before meeting with your locksmith and you
will be ahead of the game.
