Plan a key hierarchy before changing cylinders
A master-key system lets designated keys open more than one cylinder while other keys open only assigned doors. Planning starts with the doors, user groups, permission levels, and who may authorize changes. Existing cylinders must be checked before a hierarchy or expansion is promised.
Rekeying can fit when usable hardware should accept different keys. A master-key plan fits when designated access must span more than one door. The existing cylinder and access plan determine which approach is suitable.
Plan before a site review
- Door list and current cylinder details
- User groups and permission levels
- Who can approve access changes
- Who will manage future changes
Master-key questions
Can another door be added later?
It depends on the existing cylinders, key hierarchy, and the system review. The updated door and access plan should be checked before an addition is confirmed.
What happens after a key is lost?
The appropriate response depends on the affected doors, permissions, cylinders, and key-control plan. A review determines whether rekeying or another change is appropriate.
