Expert Master Key System Installation
Be Secure Locksmith installs and maintains master key systems for businesses, offices, and multi-unit buildings. For property and business owners, it’s important to have access to all parts of a building. Whether in the case of an emergency or to perform routine maintenance, master key systems improve security and simplify key management for any large property.
What Is a Master Key System?

Here’s a simplified diagram of a master key system in an apartment complex. The property owner/manager has the grand master key, the maintenance staff has sub-master keys, and each tenant has their own unique operating key.
Master key systems are a form of lock security that allows for select keys to open more than just one lock. Rather than having one key for every single lock, a single key can be used to open multiple doors. Think of the master key system as a hierarchy system—the master key opens every door on the property, and the sub-keys underneath only open the door or doors they’re designated for.
These systems provide a more secure method for property owners to gain access to portions of their community, as they limit the number of keys in circulation for a building from multiple to just one. As an example, here are the different levels of keys and who can use them in an apartment complex:
- Grand Master Key: Unlocks all locks in the apartment complex. The property owner or property manager will have this key.
- Sub-Master Key: Unlocks all apartments, the laundry rooms, the on-site gym, and more. Maintenance staff will have this key so they can carry out repairs and routine maintenance tasks throughout the property and not have to carry a huge keyring with a different key for each lock.
- Operating Key: Unlocks one apartment only. Each tenant will have a unique key that unlocks their apartment only and, depending on the property, can also unlock the laundry room, gym, and other areas shared by all tenants.
This hierarchy ensures secure and organized access to specific locks while maintaining control.
Benefits of a Master Key System
A master key system means no more overloaded keyrings for property managers and maintenance staff!
A master key system provides many advantages, including:
- Simplified Key Management: Property managers and maintenance staff no longer need to carry around a huge key ring with keys for each door.
- Improved Access Control: Restrict entry to specific areas using predefined access levels.
- Convenient Emergency Access: Ensure emergency access for supervisors or security personnel.
- Cost Savings: Reduce the need for multiple keys and rekeying services.
Facility managers and property owners benefit from the efficiency of a well-planned system.
Who Can Benefit From a Master Key System?
