Master Key Systems

A key is a physical device that allows access to an area secured by a matching lock. Most locks are designed to open only with a dedicated key that fits their mechanism. Keys may be unrestricted and widely available, or use a restricted profile requiring authorisation and available only from the locksmith who created the system.

Master key systems offer enhanced security and are designed to include a top-level master or grandmaster key that can open all locks on a site, even when different areas use separate keys. Cylinders are built to accept both standard and master keys, with access based on the user’s role or needs.

While some master keys are unrestricted, most use restricted profiles for added security—preventing unauthorised copies and preserving system integrity.
