Careful planning is key to the long-term success of a masterkey system. Planning starts with understanding the opposingforces of security and convenience, and creating the properbalance. From there, it’s easy to move onto developing thekey system structure.PlanningPlanningMaximum SecurityMaximum SecurityMaximum ConvenienceMaximum ConvenienceMaximumBuildingSecurityMinimumPersonalConvenienceMinimalBuildingSecurityMaximumPersonalConvenienceSome facilities will be heavily security-oriented. Lack ofconvenience may make it hard to operate the building ona day to day basisSome facilities will require great personal convenience.This takes away from building security.Opposing ForcesThe cylinder mechanism and the keying system muststrike the right balance between two archrivals—securityand convenience.The type and amount of cross key, the use of keyed alikegroups and the number of levels of keying all play criticalroles in this delicate balance. They also directly affect theamount of expansion available in the system.“Security”• SKD sets• Small, unrelated systems• Patented keyways• Security cylinders• High security cylinders• Key control“Convenience”• Extensive cross keying• One huge,complicated system• Stock keyway• Interchangeable core(IC) cylinders• Many selective master keys• No key controlProper BalanceThe simplest keying systems are often the most secure andwill last longer than complicated ones. Cross keying andcomplicated systems reduce security and expansion potential.BalancedBuildingSecurityBalancedPersonalConvenienceNOTE: See glossary on pages 13–16 for terms and definitions.For assistance, contact your local ASSA ABLOY Door Security Solutions team.Ask about Key Wizard ® key control software.3
