KEY CONTROL TIP
A Master Key System Is Only as Good as Its Key Control.
Document who receives each key, collect keys when roles change, and limit unauthorized duplication where possible.
A system should also leave room for future changes so one staffing change does not require rebuilding the entire hierarchy.
Master Key System vs. Keyed-Alike Locks
Keyed alike means the same key operates multiple compatible locks. Every holder of that key typically has the same access.
A master key system creates different access levels, allowing some keys to open selected doors and higher-level keys to open broader groups.
