Unit Descriptor

Unit descriptor 

This unit covers manually assembling key mechanisms.

Application of the Unit

Application of the unit 

This unit applies to assembly operations that are essentially manual in nature and require the application of accepted locksmithing principles and practices. Assembly activities typically involve built-to-order work and/or low volume and/or complex assemblies and/or long assembly timeframes.

This unit could apply to assembly of cylinders within a masterkey system and individually keyed cylinders.

Work may involve manual adjustments of locking assemblies to correct clearances and alignments to predetermined standards of quality and safety.

Applications of this unit may also require varying levels of measurement competencies. Where this is the case, Unit MEM12023A (Perform engineering measurements) or Unit MEM12003B (Perform precision mechanical measurement) should also be selected as appropriate.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA

2. Prepare to assemble lock mechanisms

2.1. Lock mechanisms are disassembled, if necessary.

2.2. Components and parts are compiled in accordance with assembly specifications.

2.3. Tools, equipment and materials are selected to suit job requirements.

2.4. Work area is prepared and components are arranged in accordance with organisational procedures and selected assembly technique.

2.5. Defective or faulty parts are identified and processed according to organisational procedures.

3. Assemble lock mechanisms

3.1. Locksmithing techniques and principles are applied appropriate to assembly activity.

3.2. Records/data are maintained or processed in accordance with organisational requirements.

3.3. Component parts are fitted to ensure correct positioning and conformance with specifications.

3.4. Locking mechanism is correctly marked/ tagged/ identified as appropriate in accordance with organisational procedure.

3.5. Components and/or assembly are handled and stored in a manner least likely to cause damage and in accordance with organisational procedure.

4. Identify the combination of an assembled mechanism

4.1. The lock mechanism and construction is correctly identified using appropriate method.

4.2. Lock mechanism is decoded (internal locking components).

5. Check finished products

5.1. Operation of the lock mechanism and key is checked for conformance to specifications.

5.2. Faults in lock mechanism or key operation are identified and rectified.

6. Mark, package and label products

6.2. Stamping equipment is selected and used correctly.

6.3. Products are grouped, packaged and labelled for installation in accordance with organisational procedures.

Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Look for evidence that confirms skills in:

  • checking components/parts against key schedule/job sheet, assembly list or equivalent instructions
  • planning assembly sequence
  • decoding key mechanisms

Required knowledge 

Look for evidence that confirms knowledge of:

  • types of mechanical locking devices
  • information on handwritten and computer generated pinning charts, key and door schedules, hardware chart, mechanical locking devices, mechanisms and components
  • the importance of obtaining authorisations
  • the difference between levers and key blanks
  • fitting requirements and sequence of assembly
  • tools, equipment and materials for assembling lock mechanisms
  • door and key reference information and stamping methods

Evidence Guide

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 assemble locking devices and produce keys from locks. 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 assembling locking devices, 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.

Guidance information for assessment
