Managing access across businesses can be a logistical challenge. With multiple doors and staff members with varying levels of access clearance and regular turnover, keeping track of who has access to where can become confusing fast. This can lead to serious issues if unauthorised personnel get access to restricted areas, and cause delays if high-level managers don’t have access to rooms that they should.
Master key systems and restricted key systems are two of the most common solutions for businesses wanting more access control, without the chaos of dozens of unrelated keys. Keep reading to find out how these advanced security systems work, the benefits they offer, and how to decide which is best for your business.
What Is a Master Key System?
Master key systems rely on a hierarchy of keys, providing different levels of access based on the key. On a technical level, these systems use pin-tumbler locks that allow multiple keys to open the same lock. In traditional pin-tumbler locks, the top and bottom pins need to align to create a shear line and unlock. Master key locks feature additional master pins between the top and bottom pins, allowing for the creation of multiple shear lines. This enables the lock to recognise multiple key patterns.
This allows business owners to provide different keys to different personnel or clients based on their access levels.
How the Key Hierarchy Works
Master keying systems feature three main levels of access:
- Grand Master Key: This key can unlock every lock in the system or building.
- Sub-Master Keys: These keys are designed to unlock doors on a specific floor, department, or specified area.
- Individual Keys: These keys are designed to only open a single designated lock.
Benefits of Master Key Systems
Master keying offers a wide range of security benefits for businesses, including:
- Enhanced Convenience: These systems reduce the number of keys high-level managers need to carry to access areas while simplifying access restrictions for unauthorised persons and areas.
- Streamlined Emergency Access: Managers and security personnel can get quick access to every area instantly to facilitate quick access during emergencies.
- Improved Access Control: Master keying hierarchies allows you to easily control who has access to specific areas, reducing the risk of unauthorised access
- Improved Accountability: When paired with restricted key systems, master keys cannot be duplicated without proper authorisation, ensuring you know exactly who has access to your property should anything happen.
Who Master Key Systems are Best Suited For
Master key systems are a popular security solution for many businesses and muti-residential complexes, including:
- Office buildings
- Apartment buildings
- Schools and universities
- Hospitals and healthcare facilities
- Warehouses and industrial sites
- Hotels and Accommodation facilities
- Hospitality establishments
What Is a Restricted Key System?
Restricted key systems use legally patented keys that cannot be duplicated without strict, authorised verification. Hardware stores and general key cutters do not have the equipment required to cut these keys, even if they do, they need strict authorisation to do so. This ensures that you always know exactly how many keys exist for your building and specific areas and can give these keys to just the authorised personnel.
The locks for these systems also feature advanced features to protect against picking, keeping your premises safe and secure.
Benefits of Restricted Key Systems
Restricted key systems offer extensive benefits for maintaining security in commercial and multi-residential facilities, such as:
- Complete Key Control: Duplicates can only be made by the specific locksmith or manufacturer who installed the system, and only when presented with a pre-authorised signature or PIN.
- Full Audit Trail: Every key is uniquely numbered, logged, and tracked ensuring you always know how many keys exist and who holds them.
- High-Level Security: Lock cylinders paired with restricted keys feature complex, high-security internal mechanics that protect against picking.
- Long-Term Security: Restricted key systems reduce the need for rekeying during staff or tenant turnover (granted all keys are returned) as keys cannot be duplicated without authorisation.
Who Restricted Key Systems are Best Suited For
Restricted key systems are ideal for any business or multi-residential complex, ensuring high-level security and key management. These systems are perfect for ensuring outgoing personnel or tenants cannot cut duplicates or retain keys upon their departure
Can You Combine Both Systems?
The terms master key systems and restricted key systems are often used interchangeably, however, as established, they are related to different security methods. This doesn’t mean that they’re mutually exclusive. Master keys are often also designed to be protected against unauthorised duplication, making them a restricted key system.
Which System Is Right for Your Business?
To ensure the highest level of security and convenience, we recommend using master key systems backed by restricted access control. This ensures simple, hierarchical access control while protecting against unauthorised access, picking, and duplication.
For businesses with a large number of staff members with differing access levels and residential or accommodation facilities with numerous tenants and maintenance staff, restricted master keying systems ensures that everyone has one the access that they should and that you retain full control.
Keep Your Business Secure with Advanced Keying Solutions
Master keying manages who can access where while restricted key systems manage who can copy the keys. Together, these systems form high-level security to ensure seamless access management and protect businesses and multi-residential complexes against unauthorised access.
