Description
This unit covers creating new commercial masterkey systems and expanding existing keying systems using even cut and rotating constant progression methods. Emphasis is on cross keying, submasterkeying, selective masterkeying, construction keying, maisoning and hierarchical systems up to and including a GGMK system.
Notes
Elements and Performance Criteria
1. Assess customer requirements
- 1.1. Physical characteristics of existing locks and other security devices are considered and requirement for additional site inspection is determined.
- 1.2. Customer access and task requirements are discussed and clarified according to organisational procedures.
- 1.3. Customer requirements are evaluated with respect to current capacity, and recommendations are made for the design of new/expanded system.
- 1.4. Personal limitations in assessing requirements for masterkey system are identified and assistance is sought from appropriate person(s) in accordance with organisational procedures.
2. Design masterkey system and system modifications
- 2.1. Commercial masterkey system is designed to meet customer complex access requirements.
- 2.2. System is checked for interchange.
- 2.3. Principles and processes 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 prepared to allow for future interpretation and design requirements.
- 3.3. 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.
Task requirements
Specific client requirements and quantities, completion times and dates, job requirements and tasks, signature authorities, OHS requirements, company requirements, compliance with relevant manufacturer requirements, warranties and service information
Expanded
Creation of excess codes to allow for lost keys, unusable codes and future customer requirements, multibroaching
Masterkey system
A generic term to describe a group of cylinders operated by more than one key
Commercial masterkey systems
Currently available commercial cylinders e.g. rotating disc tumbler (Abloy), radial pin tumbler (Kaba), pin sidebar (Bilock) and multibroach inline pin tumbler cylinders
Complex access requirements
Cross keying, submaster keying, selective keying, construction keying and maisoning
Interchange
Interchange is the all-compassing word for the different types
Accidental interchange is when a key operates a cylinder in system that it is not intended to operate
Documentation
Materials used, identified faults, warranties and recommendations, costs

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 develop and implement a masterkey system, which has complex access requirements. 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 developing and implementing a 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.
