Master Key Systems: What Business Owners Should Know

The safety of employees, products, and facilities is a top priority for every business.

Key control is the term used to describe the efficiency and security of your key management system. Locks and keys are still the best way to keep your business safe, despite advances in digital technology. It’s also a lot less expensive.

To ensure the most secure and effective key control for your organization, there are many different components. The master key system is one of them. Master keys provide high-level key access and simplified key management for employees and stakeholders who require quick and easy access to many doors. Do note that in times of an emergency, a master key system can save lives.

What is a Master Key System

A master key is a key that allows you to open multiple doors or locks within your organization. Master keys are typically only given to high-level stakeholders at a specific location. A facility manager, for example, may have a master key that opens all doors at their location. In contrast, employees may have sub-master keys that only open a single door or a limited number of doors, depending on their need for access.

How Does a Master Key Work

A master key system, at its most basic, allows two or more keys to open a single lock. To make this system work. Pin tumbler locks are frequently used. When the correct key is inserted, both pins are raised to rest on opposite sides of the shear line.

A key with the proper set of grooves is required to lift the key pins to the proper height. To convert a pin tumbler to a master key system, you must add a master wafer between the key pin and driver pin.

The difference between the master key (and the change key) determines how many master wafers are in a master key lock system. If there is a large difference between the keys, more master wafers are added to the system.

Advantages of Using a Master Key System

1. One Key for All

This master key lock system not only simplifies things but also prevents unauthorized entry to your building and theft from your business premises.

Even though security is a priority for most businesses, it can be overwhelming to determine how to keep your organization secure.

With the proper security system, you can ensure that only authorized employees have access to the areas they require and that unauthorized individuals cannot enter your business premises.

Furthermore, master types of keys provide complete control over all areas and can be used to restrict access to employees.

A master key system is an excellent method for securing your business. In addition, master keys can be inexpensive and easy to use, making them attractive for businesses seeking to secure their property.

As all doors can be accessed by the same key, this will give you more flexibility in how you want people to use your building or office space. It will also eliminate the risk of lost or stolen keys.

Having a master key chart provides security since you don’t need multiple locks on every door, which can be confusing and dangerous during emergencies.

Integrating a master key chart into your space is the optimal method for achieving this goal. This gives you complete control over who has access to which doors and buildings.

Large corporations must be able to provide access to various levels and types of hierarchical employees.

Large companies’ inability to control who has access can lead to security breaches. Fortunately, a master key system, which grants access based on employee levels, solves this problem. If there is a security breach or an emergency, you will be able to track who had access.

Disadvantages of Using a Market Key System
