Description
This unit of competency defines the skills and knowledge required to create a new masterkey system for in-line pin tumbler cylinders up to and including a hierarchical great grand masterkey (GGMK) system and maisoning. It applies to manually developing a standard (even cut) progression in-line masterkey system and using a computer masterkeying package. Where a security survey/site assessment is required unit MEM20014 Perform a site security survey should also be selected.Where cross keying, sub-masterkeying and selective keying is required unit MEM20008 Develop and implement a masterkey system should also be selected.No licensing, legislative or certification requirements apply to this unit at the time of publication.
