Using Master Key and Restricted Key Systems
Smart Security for Your Business
A master key system is a smart choice for business owners, body corporate managers and landlords, allowing a far higher level of security than offered by standard locking systems.
Master keyed locks are ones that are able to be opened by individually cut keys but also by a single master key. This allows building managers and business owners to have the convenience of complete access to the entire building with one key.
Groups of responsible staff can be given access to specific areas if required, making keys easier to manage while maintaining appropriate access control.

The Difference Between Keying Alike and Master Keys
“Keying alike” means that one single key operates all locks in a home or business. This is useful for smaller premises, however it does not restrict access.
Anyone issued with a key will be able to access all locks in a system that is keyed alike. In contrast, a master key system allows a master key to open all locks, while subsidiary keys will only open specific individual locks.
In commercial, business or residential settings, master keys and individual keys should always be restricted, meaning they cannot be copied by unauthorised persons.
Benefits of Master Keys and Restricted Keys for Business
- Ability to restrict access to sensitive areas while allowing trusted individuals complete access where required.
- Fewer keys are required, reducing key handling complexity and overall risk.
- Keys are easier to track, minimising unauthorised duplication.
- Restricted keys can only be copied by the locksmith who designed the system, preventing unauthorised key cutting.
- Restricted locks are more secure due to patented designs that prevent accidental or incorrect key operation.
Tips to Maintain a Secure Master Key System
- Don’t issue high-level keys lightly. Losing a master key can require partial or full rekeying of the system.
- Clearly communicate the consequences and costs of lost or misplaced keys.
- Always use a key register to track who has which keys and when.
- Ensure keys are returned when staff roles change or access is no longer required.
- Store spare keys in a locked safe or off-site wherever possible.
- Allocate keys based on job requirements — seniority alone should not dictate access.
- The fewer master keys in circulation, the better the overall security.
