Master Keying


Master Keying is where a series of locks work with individual keys but are also accessible using a Master Key. 
Master Key systems are hierarchical and restrict the access people have to areas of a building. For example, a manager may be able to open all doors in a building whereas a staff member may only be able to open the front door and their office door. 
Master Keyed systems come in the following formats: 
  • Grand Master Key:   Access to all locks, all departments, all sites
  • Master Key:             Access throughout a single building/department
  • Keyed to Differ:       Key Access to individual offices
Scott Murray Security Services are specialists in Master Key systems. We follow strict guidelines to ensure your keying system is not compromised by verifying that the authority criteria has been met prior to keys being issued.
