Master Key Systems
Master Key Systems for Memphis, TN Businesses and Commercial Properties
Managing multiple doors doesn’t have to mean carrying a large set of keys. A master key system allows you to unlock several doors with a single key while controlling access to specific areas. At The Lock Doc, we install master key systems for offices, retail spaces, warehouses, schools, apartments, and commercial buildings throughout Memphis, Germantown, Bartlett, Collierville, Cordova, Southaven, and Olive Branch.
We help property owners simplify security by creating systems that combine door locks, cabinet locks, and padlocks under unified key control. Our team provides professional locksmith services to design access plans that match your building’s layout and security priorities.
How a Master Key System Works
In this Master Key System, the property manager and owner have Master Keys, the maintenance staff have Sub-Master Keys, and each tenant has their own Child Key that only open their apartment.
A master key system uses a pin tumbler system with added master pins inside the lock cylinder. This design allows both individual keys and a master key to open the same lock. We create a key plan that defines who can access each area, whether through a single master key, sub-master keys, or higher-level keys like grand master keys.
Benefits of a Master Key System
A properly installed system provides:
- Fewer keys to manage while maintaining controlled access
- Defined access to restricted areas or specific doors
- Emergency access to multiple locks with one master key
- Long-term savings by reducing the need for complete lock replacement
- Simplified key management for businesses with multiple entry points
This solution improves key control while maintaining strong security across your property.

FAQs About Master Key Systems
What is a master key system?
A master key system uses master pins inside the lock cylinder to allow different keys to open the same lock while a master key provides access to all the locks in the system. This approach combines key control and convenience across multiple door locks.
Can I use one master key for all locks in my building?
Yes. If your door locks are compatible and part of a master keyed system, we can configure them so one key opens multiple locks. We design the master key system schematic to match your building’s key plan and security needs.
Can I add more doors to my master key system later?
Yes. We design master key systems to be expandable. You can add more locks, create sub master keys, or even move toward a grand master key or great grand master key setup for increased security and access flexibility.
What types of locks work with a master key system?
We work with pin tumbler systems, high-security locks, and many commercial door locks. If they follow the same model or are compatible, we can also include cabinet locks, padlocks, etc. We help select the right lock types to support your key control goals.
Is a master key system secure? Is it cost-effective?
Yes. A master key system provides controlled master key access while keeping individual locks secure. Using restricted keys or high-security locks further protects against unauthorized duplication or tampering. We ensure overall security through careful planning.
How much does a master key system cost?
The cost of a master key system depends on the number of keys, doors, and access levels you need. We provide upfront pricing based on the number of locks included, whether you need sub master keys, and the complexity of the key plan.
What happens if I lose a master key?
If a master key is lost, we can rekey the affected locks, issue new keys, and restore master key security without a complete lock replacement. This protects your system while avoiding the cost of replacing all the locks.
