Designing Master Key Systems for your business: Meeting Security Objectives for Effective Key Control and Management

When it comes to ensuring the desired level of security for a facility or building, a well-designed and properly maintained master key system is crucial. The convenience and benefits of having master key systems and restricted keys are undeniable. ASSA ABLOY Australia provides a comprehensive range of products and services to assist in implementing and expanding master key systems. From meeting security objectives to key control and maintenance, each step in the process is essential for an effective and secure system. 

Step 1: Meeting Security Objectives

The first step in designing a master key system is to determine the security objectives of the facility or building. This involves understanding the opposing forces of security and convenience and finding the right balance between the two. While some buildings prioritize high security, others may require greater convenience. It is important to consider proper balance. The simplest keying systems are often the most secure and will last longer than complicated   ones. Cross keying and complicated systems reduce security and expansion potential. A system designed around personnel will inevitably have a shorter life than that of a system designed around a building or structure. 

Step 2: Planning

Careful planning is key to the long-term success and lifespan of a master key system. The planning process begins with developing a key system structure based on the security objectives identified in step one. This structure can be visualized as an organizational chart, with different levels representing departments, buildings, or geographic areas within the facility. Additionally, core areas such as maintenance rooms should be considered separately and key symbols assigned accordingly. By thoroughly planning the system structure, it becomes easier to move forward with the design process.

Step 3: Assigning Key Symbols

Assigning key symbols is a critical aspect of designing a master key system. Key symbols are alphanumeric designations used to identify the correct key combination for a specific door or group of doors. In a system with multiple levels, the change key numbers come last, while master keys have designated letters or numbers. The use of standardized key symbols simplifies key control and management, ensuring that the correct keys are assigned to the appropriate individuals.

Step 4: Key Control and Key Management

Key control and management are essential for the security and longevity of a master key system. Key control policies and procedures play a vital role in preventing unauthorized access and maintaining the integrity of the system. ASSA ABLOY offers a comprehensive key control guide that can assist in designing these policies and procedures. By implementing effective key control measures, such as restricting key duplication and maintaining accurate records of key holders, the risk of security breaches can be significantly reduced.

Step 5: Service and Maintenance

Regular service and maintenance are crucial for ensuring the optimal performance of a master key system. Periodic inspections and maintenance activities help identify and address any issues or potential vulnerabilities in the system. It is recommended to work with experienced professionals who can provide ongoing support and maintenance services to keep the system in top condition. By proactively addressing maintenance needs, the system's overall security and functionality can be upheld over time.

Step 6: Intellectual Property

Intellectual property refers to any proprietary information or designs associated with the system. It is essential to work with trusted manufacturers and service providers who respect and protect intellectual property rights. By safeguarding intellectual property, the integrity and uniqueness of the master key system can be maintained.

Finally, designing a master key system requires careful planning, attention to detail, and a comprehensive understanding of security objectives. By following the key steps outlined above, including meeting security objectives, planning, assigning key symbols, implementing key control and management measures, and focusing on service and maintenance, an effective and secure master key system can be designed. Additionally, considering intellectual property rights ensures the protection of proprietary information associated with the system. With the assistance of experienced professionals and the right products and services, facilities and buildings can achieve the desired level of security and convenience with their master key systems.
