Develop and implement a masterkey system

Assessment tool

Version 1.0
Issue Date: May 2024


This unit applies to writing masterkey systems for high security cylinders, primarily for commercial operations.

Systems are written manually and using a computer masterkeying package.

All relevant legislative requirements, policies and procedures and codes of practice are adhered to including hazardous and risk assessment, use of codes of practice, ergonomics.

If a security survey/site assessment is required, then Unit MEM20014A (Perform a site security survey) should also be selected.

For standard hierarchical keying, refer to Unit MEM20007A (Plan and prepare a masterkey system).

Band:

This unit has dual status and is to be regarded as both a Specialisation band A unit and Specialisation band B unit for progression to C5 (AQF level V).

Unit Weight: 6

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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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 in-line 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 plugs/barrels

expanding an existing key system by converting the progression from even cut to rotating constant

creating/saving and storing information/documentation

applying calculations and formulae within the scope of this unit

Required knowledge

Look for evidence that confirms knowledge of:

record keeping and management

manufacturers'/Australian/building standards

product knowledge/limitations

key matrixes and schedules

allowances for expansion

operation and limitations of masterkey systems

levels of systems (KD, KA, MK, GMK, GGMK)

door handing

cylinder types

principles of construction keying, submaster keying, cross keying, selective keying, maison keying

criteria for key code selection

strategies for checking key systems for interchange

strategies for checking key systems for incidental masters

strategies for using incidental masters to create submaster keys, cross keys and selective keys

strategies for selecting groups of codes to form a maisioned cylinder

calculations and formulae within the scope of this unit

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

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
