Master keying and restricted key systems give you greater control
A master key system gives different people different levels of access while allowing selected keys to operate multiple locks.
Fleurieu Locksmith designs, supplies and maintains master key and restricted key systems for businesses, commercial properties, schools, property managers, community facilities and other organisations across Victor Harbor, Goolwa and the Fleurieu Peninsula region.
Systems can range from controlled restricted key duplication for a smaller business to a structured master key hierarchy covering multiple doors, buildings and user groups. The system is planned around who needs access, which areas they can enter and how keys will be managed as requirements change.


Master key systems manage access across your property
A master key system allows multiple locks to operate within an organised key hierarchy. Individual users can be given access only to the doors they need, while nominated keys can operate larger groups of doors.
For example, an individual staff key may open selected doors within one area. A department or area key can operate a defined group of locks, while a master key can provide access across several areas. A grand master key can sit above these levels where a larger system requires it.
This reduces the need for authorised personnel to carry numerous separate keys while maintaining different access permissions across the property.
Restricted key systems add another layer by controlling who can request additional copies of keys.
Master keying and restricted key systems services
The right system depends on your property, users, existing locks and future requirements. We can assist with the design, implementation and ongoing management of the key system. Fleurieu Locksmith supplies and manages ML20, BPA and J Series restricted key systems.
Master key system design
Access levels can be planned around individual users, departments, areas, buildings or other nominated groups.
Restricted key system design
Restricted keys can be used to provide greater control over authorised key duplication.
Access hierarchy planning
Individual, area, master and grand master key levels can be organised according to required access permissions.
Door and cylinder schedules
Locks and cylinders can be recorded as part of the overall keying structure.
Restricted key registration
Key systems can be established and maintained with controlled key profiles.
Key numbering and identification
Keys can be identified within the system to support ongoing management.
Authorised key holder records and signatory control
Key records and authorised signatories can support controlled key issue, replacement restricted keys and duplication requests.
Existing lock integration
Suitable existing locking hardware may be incorporated rather than automatically replaced.
System expansion and replacement restricted keys
Additional doors, locks and users can be incorporated as requirements change, with replacement restricted keys supplied through the authorised system.
System rekeying
Existing systems can be reviewed and lock rekeying where appropriate.
Master key systems suit properties and clients with multiple access needs
Different organisations have different reasons for introducing controlled key access. The common requirement is a practical way to manage who can enter nominated areas and who can obtain additional keys.
Businesses and commercial properties
Offices, retail premises, workshops, warehouses and other commercial buildings may have staff who require different levels of access. A master key hierarchy can separate general access from areas that only nominated personnel need to enter.
Schools, councils and community facilities
Schools, education facilities, government facilities, councils and community organisations can have numerous doors and different user groups. Structured keying allows access permissions to be organised around those requirements.
Property and facility managers
Property managers, strata and body corporate properties, apartment buildings and multi tenancy sites may need to manage access across different areas while retaining higher level access for authorised management personnel.
Aged care and accommodation properties
Aged care facilities, holiday accommodation and property portfolios may also benefit from structured access levels and controlled key duplication.
Better key control starts with two separate decisions
Master keying and restricted keying perform different functions and combining them can provide two forms of control within one system.
Access control determines which doors a key operates
One user may have access to a single area, another to several areas and an authorised manager to a wider part of the property.
Key control manages the duplication of restricted keys
Unlike commonly available key profiles, additional restricted keys are supplied through an authorised system.
Combining these functions means a person can carry one key that operates only the doors assigned to them while the organisation retains greater control over additional key requests.
The result is a key system designed around access permissions rather than simply making every lock work from the same key.
Restricted key systems control how additional keys are issued
A restricted key system uses a controlled key profile rather than a commonly available standard key.
We can establish, register, maintain and expand restricted key systems using ML20, BPA and J Series profiles. The appropriate option depends on the property, required level of key control, size of the system and anticipated future expansion.
Restricted keying can also form part of a master key system. This allows the key hierarchy to determine where each person has access while the restricted system manages authorised duplication.
Ongoing management is important because key systems rarely remain static. Staff change, additional doors are installed, responsibilities change and new users may need different access permissions. A well planned system provides a structure that can accommodate these changes.
Your master key system is planned for current and future access
A master key system starts with understanding the property and how people need to move through it. Existing systems can also be assessed when changes are required. This can include adding new locks, rekeying individual doors, changing access permissions, issuing additional authorised keys, replacing lost keys and expanding the system. If keys are lost or unaccounted for, Fleurieu Locksmith can also review the security of the existing system and determine an appropriate response.
Our typical master key process includes:
Step 1
Reviewing the access requirements
We identify the doors, areas and user groups that need to form part of the system.
Step 2
Planning the key hierarchy
Access permissions are organised so individual, area and higher level keys operate the appropriate doors.
Step 3
Selecting the key system
Where restricted duplication is required, an appropriate ML20, BPA or J Series system can be considered.
Step 4
Preparing the system structure
Door and cylinder schedules, key identification and authorised key holder requirements can be established.
Step 5
Implementing the system
Suitable locks can be keyed into the planned hierarchy, including existing hardware where appropriate.
Step 6
Managing future changes
Additional doors, users and authorised keys can be incorporated as the organisation develops.

Who provides master key and restricted key systems around Victor Harbor?
Fleurieu Locksmith designs, supplies and maintains master key and restricted key systems across Victor Harbor, Goolwa and the Fleurieu Peninsula region.
Systems can be designed for businesses, schools, commercial properties, property managers, community facilities and other organisations requiring controlled access across multiple doors or user groups.
How does a master key system work if different staff need different access?
The system is designed as an access hierarchy. Individual keys can operate nominated doors; area keys can cover groups of doors and master keys can provide wider access.
Fleurieu Locksmith plans the hierarchy around the property, users and required access permissions, then integrates suitable locks into that structure.
What affects the type of restricted key system I need?
The appropriate system depends on factors including the property, level of key control required, number of doors and users, existinglocking hardware and likely future expansion.
Fleurieu Locksmith can assess these requirements and recommend an appropriate ML20, BPA or J Series restricted key system.

Frequently asked questions about Master key and restricted key systems in Fleurieu Peninsula
What is the difference between a master key system and a restricted key system?
A master key system determines which locks each key can operate. Different keys can therefore provide different levels of access within the same property.
A restricted key system focuses on key duplication control. Additional restricted keys are managed through an authorised system rather than being copied in the same way as a commonly available key profile.
The two systems can be combined. This allows an organisation to control both the doors each key operates and the process used to obtain additional keys. Fleurieu Locksmith can design systems incorporating these functions where they are appropriate to the property and access requirements.
Can one key operate several doors without opening every door?
Yes. That is one of the main functions of a master key hierarchy.
A key can be configured to operate only a defined group of compatible locks. For example, a staff member may have one key that opens their work area and selected common doors without opening other restricted areas. Another authorised person may hold a master key that operates a wider group of doors.
The exact hierarchy depends on how access needs to be divided across the property. Fleurieu Locksmith can plan individual, area, master and grand master levels where required.
Can an existing master key system be changed or expanded?
Existing master key systems do not automatically need to be replaced when requirements change.
We can assess an existing system and, where possible and appropriate, assist with adding locks, rekeying individual doors, changing access permissions, issuing authorised keys and expanding the system for additional doors or users.
The available options depend on the existing key system, locking hardware and the changes required. Reviewing the existing system first can identify which components can continue to be used and where changes are needed.
What happens if a master key or restricted key is lost?
Losing a master or restricted key does not automatically mean the entire system needs to be replaced.
The appropriate response depends on the level of the missing key, which doors it operates, and the security risk associated with it. A key with access to one limited area presents a different issue from a key operating a large part of the system.
Fleurieu Locksmith can assess the existing hierarchy and determine an appropriate rekeying strategy, including which locks or parts of the system may need to be changed to restore key control.
Which restricted key systems does Fleurieu Locksmith supply?
We can supply and manage ML20, BPA and J Series restricted key systems.
The appropriate profile depends on the property, system size, required level of duplication control and future expansion requirements. Restricted keying can be used as a standalone system where controlled duplication is the main requirement or incorporated into a master key hierarchy where different users also need different access permissions.
Fleurieu Locksmith can establish the system, register it, manage authorised keys and assist with additions and changes over time.
Can existing locks be incorporated into a master key system?
Suitable existing locks may be able to form part of a new or revised master key system.
This depends on the locking hardware, cylinders, key profiles and the requirements of the proposed system. Where existing locks are suitable, Fleurieu Locksmith can consider integration as part of the system design rather than assuming all hardware needs to be replaced.
Existing systems can also be rekeyed or expanded where appropriate. The first step is to assess the current locks and keying arrangement against the access hierarchy and restricted key requirements you want to establish.
