Unit Descriptor

Unit descriptor 

This unit covers gaining entry and straightforward return to service of general types of mechanical locks.

Application of the Unit

Application of the unit 

The unit applies to gaining entry into commercial and domestic locks. The basis for entry includes lockout (keys inside), lost keys (rekeys) and malfunction. Applications include locks for doors and windows.

It requires an ability to safely gain straightforward entry to mechanical locking devices, taking into account factors that ensure conformance to specifications and operational performance.

These include locksmithing principles, ethics, techniques, procedures and safe work practices.

Where specialised skills are required to gain entry and to reinstate both mechanical and electronic locking systems in automotive or fire and security containers, the appropriate units should be selected.

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 gain entry to a range of mechanical locks across a range of applications. 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 gaining entry 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
