Application

This unit of competency defines the skills and knowledge required to carry out maintenance of a range of mechanical locks and locking systems in commercial, industrial and domestic environments.

It covers the ability to identify maintenance requirements, use safe and efficient work practices to inspect, service and repair mechanical locks/locking systems, and accurately document and maintain information systems.

Where maintenance and servicing of safes is required, unit MEM20032 Service and repair fire and security containers should also be selected.

Where maintenance and servicing of automotive locks is required, unit MEM20033 Service and repair mechanical automotive locking systems, unit MEM20018 Identify and program transponder keys, unit MEM20019 Service automotive transponder systems using diagnostic equipment and unit MEM20020 Use EEPROM programmers to service automotive transponder systems, should also be selected as appropriate.

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

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

interpreting and following specifications, charts and diagrams and communicating in a clear and concise manner when maintaining and servicing mechanical locking devices

identifying work health and safety (WHS) hazards and risks and implementing appropriate risk control measures and procedures

selecting the appropriate tools and equipment to complete the task

carrying out routine maintenance on mechanical locking devices on at least two occasions

cleaning worksite in accordance with original presentation, client requirements, industry standards and SOPs

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)

types, functions, specifications and operational principles of mechanical locks and/or locking systems

types of information on work orders and other documentation requirements

maintenance requirements of mechanical locks and locking systems and associated tools, equipment and materials requirements

common mechanical lock and locking system faults

tests to confirm lock operation

procedures to disassemble and reassemble mechanical locks

technical terminology

types of doors and windows and mechanical locking system applications

hazards and control measures associated with maintaining and servicing mechanical locking devices.

Assessment Conditions

Assessors must:

have vocational competency in maintaining and servicing mechanical locking devices 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.

Foundation Skills
