Description
This unit covers creating a new masterkey system for in-line pin tumbler cylinders up to and including a hierarchical GGMK system and maisoning.
Notes
Elements and Performance Criteria
1. Assess customer requirements
  • 1.1. Customer needs are discussed and clarified according to organisational procedures.
  • 1.2. Appropriate levels of security/access are reviewed with respect to customer assets, activities and existing security arrangements.
  • 1.3. Door and lock schedules and other appropriate documentation are prepared according to organisational procedures.
  • 1.4. Customer requirements are matched to the mechanical possibilities and limitations of masterkey systems.
  • 1.5. Options are identified and customer is advised on options and alternatives.
  • 1.6. Personal limitations in assessing requirements for key systems and masterkey systems are identified and assistance is sought from appropriate person(s) in accordance with organisational procedures.
2. Design masterkey system
  • 2.1. Keying matrix is developed to customer requirements, allowing for future system expansion and mechanical capabilities of system.
  • 2.2. Key codes (progression chart) are produced from mathematical permutations and calculations as per customer requirements.
  • 2.3. Key codes are selected from progression chart that maximise system security.
  • 2.4. Key cutting and cylinder loading charts are accurately developed.
  • 2.5. Incidental masterkeys are identified within progression charts.
  • 2.6. Principles of masterkeying are applied in accordance with industry practice and organisational requirements.
3. Finalise system design
  • 3.1. Final system design and keying requirements are reviewed and confirmed with appropriate person(s) in accordance with organisational requirements.
  • 3.2. Documentation is accurately prepared and processed and stored in accordance with client, legislative and organisational requirements.
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Reviewed

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
A person who demonstrates competency in this unit must be able to survey and prepare a masterkey system to in-line GMK level. Competency in this unit cannot be claimed until all prerequisites have been satisfied.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with surveying and preparing masterkey systems, or other units requiring the exercise of the skills and knowledge covered by this unit.
Method of assessment
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
