Master key systems don’t just open doors; master key systems establish a fortress of security within apartment living and multi-unit properties.
Some people think they have a master key because it is a key that can open many locks. In most cases, the locks are keyed alike and not part of a master key system. Implementing a master key system can enhance security in residential and commercial properties.
Any master key system that features different access levels has to be tailored specifically for each building or group of buildings to fit security needs. If you need to implement master key systems, Locksmith United offers affordable commercial locksmith services.
What is a Master Key, and How Does it Work?
If you have a master key system for multi-unit properties, you’ll know because you’ll have one key that overrides all the locks in the system.
None of the individual apartment keys will fit each other, but one master key will gain entry to all locks. A master key system provides a blueprint for building security and allows and restricts property access.
As of 25th January 2023, all Master Key systems of Series 1, Series 3, and Series 5 were supplied with coded keys (code engraved on the head) and accompanied by the MK system diagram.
This upgrade is available at a standard cost from Locksmith United at no extra charge. The key code and MKS diagram help with installation and make it possible to keep track of the accesses on which the locks were installed.
How to Plan a Master Key System
A master key system (MKS) refers to a group of locks and their operating keys. This works in a hierarchy with the master key (MK) at the top, which fits into numerous locks. There are four factors to take into consideration when planning a system.
- How many locks are in the system
- Who controls the key distribution
- Brand or manufacturer of the keys and locks, which is the most significant security determinant.
- Security needs
Master Key System for Builders
Keep in mind that the master key system for builders is different in that it’s temporary and is effective only throughout the building phase. It operates all the locks designated for its use. The contractor permanently voids the key when the owner takes possession of the building.
Master Key Systems for Multi-Level Access
Master key systems give you multi-level access whereby the lower-level keys may only have access to one particular lock. The next level up could provide you access to a group of locks in the master key system, and the highest level may give you access to all of the locks.
Benefits of a Master Key Security System
If you’re wondering about the benefits of a master key system for multi-unit properties, there are many advantages. The first one is increased security related to controlling and restricting access.
The downside is that if the key is lost or stolen, it can pose a significant security risk. If a master key is lost, all locks in which it operates must be rekeyed.
Nonetheless, there are many benefits, like convenience and overall control with the master key. There’s no need to carry a heavy bunch of keys for maintenance workers or apartment managers. Master key systems are designed to make life easier and safer. Here are some other benefits of a master key security system.
- Designated keys can open several pre-defined doors.
- A named key, such as AA10, could be designed to operate a certain number of locks, including doors, cabinets, and padlocks if the cylinder inside them is the same model.
- Suitable for multi-utility companies, public and private companies for energy, water, gas, and waste, apartment building buildings, and multi-unit properties.
- Allows for simplified key management to open multiple locks with one key.
- It reduces the number of keys and lets you monitor and control different areas of property by limiting access to specific groups of employees.
Different Types of Master Keys
Each lock is operated by a separate key (change key). A master key can open multiple locks in the system, but the fewer master keys, the safer the system. Elementary schools use master keys to open all classrooms. Different types of keys open multiple locks or a specific group of locks. Here are a few examples:
Great Grand Master Key(GGMK): This can be designated and cut to open the exterior and interior doors. Master key systems are designed along departmental or functional groups for supervisory or emergency access to specific personnel.
Grand Master Key (GMK): This is a key that only opens designated doors. There may also be lower branches of a master key that open an entire subset of locks. The grand master key can open all of the locks, which lower master keys can open, too.
Change Key(CK): This will usually only open one door or room to an office or building. It is the most restricted key in a master key system, providing access to a single lock. Change keys are ideal for individual users who only need access to their specific area, such as an employee’s office or a tenant’s apartment. They help maintain security by limiting access to only the necessary spaces.
Residential Master Key(RMK): This specialized key is used only for residential properties to open multiple locks within an apartment building. It allows for different levels of access to various locks within the property. For example, a homeowner may have separate keys for all home entrances, like the front door, back door, and garage, and the residential master key will open all the locks.
Final Thoughts
A master key system is essential for security and convenience and for operating multi-unit properties with multiple access points. A master key system installation depends on the type of system you choose and the compatibility of the new locks.
