Master Key Systems
Streamline Access with Master Key Systems
Simplify your business’s security with a master key system. This system allows you to control access to various areas within your property with a single key, providing both convenience and enhanced security. Our expert locksmiths design and install custom master key systems tailored to your specific needs, ensuring that only authorized personnel have access to restricted areas.
Commercial Master key locks are a type of locking system commonly used in buildings where multiple locks are installed. Also, there is a need for different levels of access control. These locks are designed to be opened by two different keys: a master key and a regular key. Here’s how they work:
Regular Key
Each individual lock has its own unique regular key, which can only open that specific lock.
Master Key
The master key is a special key that can open multiple locks within the system. It provides access to all the locks in the system, allowing a designated person (such as a building manager or security personnel) to access all areas.
Master Key Hierarchy
Master key systems can be hierarchical, meaning that there can be different levels of master keys. For example, there can be a grand master key that opens all locks in a building, and then sub-master keys that open specific groups of locks. Security: It’s crucial to maintain the security of master key systems. If a master key falls into the wrong hands, it could potentially compromise the security of the entire building.
Understanding the Key Components
To master key a lock, it is crucial to understand the role of bottom pins and master pins (top pins). Let’s take our master key, AMK 21426. The A1 key, for this example, is numbered 43448. The process begins with a simple concept: selecting the lowest number between the master and the secondary key to determine the bottom pins. Here’s a breakdown:
AMK: 21426
AA1: 43448
Master Pins: 2, 2, X , 2, 2
Bottom Pins: 2, 1, 4, 2, 6
The master pins are calculated by subtracting the bottom pin number from the top pin number, rendering a basic and effective system for customization.
The Process of Master Keying
Let’s translate the theory into practice. Start by removing the lock cylinder from its casing, which could be a mortise or a kick cylinder. Key features like lazy cams might be present, but they don’t interfere with the master keying process.
Preparation: Extract the pins from the lock cylinder and set them aside. For this example, we’re utilizing a 5 pin, 6 pin cylinder system.
Inserting Bottom Pins: For each slot in the cylinder:
Place a bottom pin corresponding to the A1 key – numbers like 2, 1, and 4 are crucial for proper alignment.
Adding Master Pins: Insert the corresponding master pins, ensuring the proper balance for easy operation with both the main and secondary keys. Remember, no pin is placed in the ‘X’ position.
Reassembly: Insert the pins into their designated slot in the cylinder, taking note of marker placements to denote top and front sections of the lock.
Testing and Final Touches
With the key pins in place, test both the A1 and master keys to ensure smooth operation. The A1 should operate flawlessly, as should the master key. If any issues arise, revisit the pin placements and ensure they align with the key’s bitting.
Olden-day locksmiths traditionally used graphite to ensure smooth operation post-assembly, but modern preferences lean towards Tri Flow, a lubricant that ensures longevity without the harmful effects of graphite or other traditional oils like WD-40.
