Elements and Performance Criteria

1. Assess customer requirements
   • Physical characteristics of existing locks and other security devices are considered and requirement for additional site inspection is determined.
   • Customer access and task requirements are discussed and clarified according to organisational procedures.
   • Customer requirements are evaluated with respect to current capacity, and recommendations are made for the design of new/expanded system.
   • 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
   • Commercial masterkey system is designed to meet customer complex access requirements.
   • System is checked for interchange.
   • Principles and processes of masterkeying are applied in accordance with industry practice and organisational requirements.
3. Finalise system design
   • Final system design and keying requirements are reviewed and confirmed with appropriate person(s) in accordance with organisational requirements.
   • Documentation is prepared to allow for future interpretation and design requirements.
   • Documentation is accurately prepared and processed and stored in accordance with client, legislative and organisational requirements.

Required Skills

Required skills

Look for evidence that confirms skills in listening and questioning reading architectural plans floor plans and charts evaluating system and expansion requirements determining the required structure of a keying system based on customer requirements developing key matrix developing and reading progression charts for inline key systems using even cut and rotating constant methods developing and reading progression charts for rotating disc radial pin and pin sidebar key systems selecting codes from progression chart that maximise system security checking own and others codes for interchange identifying incidental masters in a key system and using them to achieve complex access requirements selecting groups of codes to form a maisioned cylinder determining the structure of the design of an existing system and the maximum number of codes that can be produced identifying any unused codes in an existing system expanding an existing key system by using multibroached plugsbarrels expanding an existing key system by converting the progression from even cut to rotating constant creatingsaving and storing informationdocumentation applying calculations and formulae within the scope of this unit

Evidence Required

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 supervisors 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

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
