Application

This unit of competency defines the skills and knowledge required to create a new master key system for in-line pin tumbler cylinders up to and including a hierarchical great grand master key (GGMK) system and maisoning. It applies to manually developing a standard (even cut) progression in-line master key system and using a computer master keying package.

Where a security survey or site assessment is required unit MEM20035 Perform a site security survey should also be selected.

Where cross keying, sub-master keying and selective keying is required unit MEM20029 Develop and implement a master key system should also be selected.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

What You'll Learn

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

discussing customer requirements and reviewing appropriate levels of security and access

interpreting architectural plans, floor plans and charts when planning and preparing a master key system

recognising personal limitations in assessing design requirements for key systems and master key systems with supervisor in accordance with SOPs

identifying the appropriate key system and levels according to customer requirements on at least two occasions

undertaking numerical operations and calculations, including mathematical patterns associated with planning and preparing a master key system

developing a master key system and key matrix on at least two occasions, allowing for future expansion

developing and reading code matrix and selecting codes that maximise system security on at least two occasions

select a group of codes to form a maision cylinder, including the identification of any ghost codes that will operate in the cylinder on at least two occasions

completing all documentation in accordance with SOPs.

Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

record keeping and management

types of manufacturer standards, Australian Standards and building standards that impact master key work

product knowledge and limitations

code matrices, key and door schedules

allowances for expansion

operation and limitations of master key systems

tiers of systems including:

keyed different (KD)

keyed alike (KA)

master key (MK)

grand master key (GMK)

great grand master key (GGMK)

door handing and cylinder types

criteria for key suitable key selection for interchange and incidental masters

strategies for checking key systems for interchange and incidental masters

strategies for checking key systems for phantoms

principles of maison keying.

Assessment Conditions

Assessors must:

have vocational competency in planning and preparing a master key system at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires.

Where possible, assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
