Master Lock 770LHCNMK Master Keyed Bump Padlock

Consider A Fleet Where Individual Drivers Or Technicians Should Only Have Access To Their Assigned Vehicles And Keying Alike Each Lock Would Allow Full Blow Access To Every Vehicle. With A Properly Designed Master Key System, Individual Locks Can Instead Have Their Own Operating Keys While An Authorized Supervisor Carries The One Master Key.

Q: What Is The Main Purpose Of A Master Keyed System?
A: Unlike A Simple Keyed Alike System, A Master Key System (Featuring The 770LHCMK Or Bump Stop 770LHCNMK) Can Allow Individual Locks To Retain Their Own Operating Keys While An Authorized Master Key Is Able To Operate Multiple Locks Within The System. 

Q: Does A Master Key Mean Every Regular Key Opens Every Lock?
A: No. That's An Important Difference: In Keyed Alike Systems Individual Operating Keys Can Be Assigned To Specific Locks While Master Keying Provides Broader Access.

Q: Who Normally Carries The Master Key?
A: Master Keys Are Typically Controlled By Fleet Managers, Supervisors, Facility Managers, Owners Or Other Authorized Personnel Who Require Access To Multiple Secured Locations.

Q: Can Existing Master Keyed Systems Be Expanded?
A: In Many Cases, Yes. However, Master Key Systems Should Be Treated Differently Than Ordinary Off-The-Shelf Padlocks And Existing Key System Information Should Be Provided In Order To Have Any New Locks Properly Configured Within Their Established System.
