Restricted security key systems are available in various levels of security from standard security to medium and high security. We will taylor a restricted security key system to suit your specific security requirements.

What is a Restricted Key System?

Restricted security keys require authorisation by you and/or an elected person for key duplication, providing quality and security for any application you may require. Combine this with a computer operated key management system and you will always know who has your keys.

Restricted key systems provide key control and access control and are suitable for applications including:

  • Residential

  • Apartment Complex
  • Hotels and Resorts
  • Schools
  • Councils
  • Mining
  • Government Facilities
  • Hospitals and Health Care Facilities

Steps to Better Key Security
