Pros and cons of a master key system

Irrespective of whether it’s in commercial or residential places, they are very helpful when it comes to opening a door if there’s an emergency. Just like any other system, a master key system has its own advantages and disadvantages. Going through its pros and cons can assist you in deciding whether it’s the best solution for your premises or not.


1. Easy access to several units

This is the biggest advantage of a master key system. If there’s an emergency situation in your commercial or residential units such as fire outbreak, you can easily unlock the doors so that people can run for their safety. It also eases the process of performing maintenance. In an office setting, your employees only need a single key to open the doors, which helps to minimize time wastage thus increasing work output.

2. They’re affordable

Many people don’t think of this benefit since the installation of the system seems to take long and is difficult. However, it should be understood that it’s a very affordable solution to your premises. For instance, if a tenant moves from a business house, the lock will only be re-keyed, and no replacement will be made. What’s required here is only the repositioning of the lock cylinder and the pins. By doing this, the lock will continue working with the initial master key, but not the one that the tenant had. The process of rekeying a lock is much cheaper compared to replacing the entire lock.

3. Effective control of access to unauthorized spaces

A master key system effectively controls access to unauthorized spaces. For instance, you may want to keep your employees out of conference rooms, supply closets and some offices. In this case, a master key system will work best.


1. A lot of care is required to ensure master keys don’t go in wrong hands

This is because a single mistake can lead to a lot of damages and losses because someone can easily access every unit in your commercial or residential places. You’ll also be tasked to keep an eye on who has the key every time so that he or she is accountable for any unusual circumstance that appears.

2. It’s expensive to change the whole system

In case you lose the master key, you may be required to change the whole system, which can be expensive.

3. Changing locks will make the system to fail

If your tenants change the door locks without your knowledge, the master system won’t work.
