Alpha Locks replaced all the locks in our office building. They were punctual, professional, and their prices were very reasonable. Will definitely use them again for our other locations!

Master Key System Design and Installation in Westchester County
A master key system gives you convenience without giving up control. I am Oren, a licensed Westchester locksmith, and I map your building, design the key hierarchy, and install it, so one key opens what it should and nothing it should not.
- One master key, individual door keys
- Expandable, documented design
- Upfront flat-rate quote before I start
About this service
A master key system organizes access across your building into a logical hierarchy: individual keys work only on assigned doors, while master keys open broader groups of locks. That gives owners and managers convenience without sacrificing separation between tenants, departments, or restricted areas. I design and install master key systems throughout Westchester County.
The design starts with an access matrix, I map every door, identify who needs access where, and build a pinning schedule that supports today's operations and tomorrow's changes. A well-designed system can grow with new doors and sub-master levels without rekeying the whole building. I work with all the major commercial brands and can usually integrate with your existing hardware.
I hand you a complete key-control chart documenting every cylinder, key level, and door assignment. That record is essential for ongoing management, whether you are onboarding a new employee, replacing a lost key, or adding a door. Every installation is done on-site and includes key cutting, cylinder pinning, and function testing of every lock.
What I include
- Door-by-door access mapping
- Expandable pinning schedule
- On-site cylinder pinning and key cutting
- Complete key-control chart
Why people in Westchester call me
- I build the hierarchy so it can grow with sub-master levels and new doors, so you are not rekeying the whole building later.
- You get me, Oren, the owner. I answer the phone myself and I do the work myself, no call centers and no subcontractors.
- I give you a clear, flat-rate quote before I start, so the price I say is the price you pay.
- I am a licensed (NY #2108832-DCA), insured and bonded locksmith, and I back every job with a 5-year warranty.
- I live and work in Westchester County, so I know the area and I get to you fast.
Frequently asked questions
What is the benefit of a master key system?
It lets managers carry one key that opens every door, while tenants and staff each get a key that only opens their own space. It simplifies access and improves security management.
Can you match existing hardware?
In most cases, yes. I can repin your current locks to work with a new master-key hierarchy, which saves the cost of replacing all your hardware.
How many levels can a master key system have?
Anything from a simple two-level setup, master plus individual, to a multi-tier hierarchy with grand master, master, sub-master, and change keys, ideal for large or multi-tenant buildings.
Is a master key system right for apartment buildings?
Absolutely. Apartments are one of the most common uses. Each tenant has a private key while the manager holds a master key for maintenance and emergencies.
How much does a master key system cost?
I provide a complete, flat-rate quote during the initial consultation, based on the number of locks and keying levels. For typical pricing on this service, see my pricing page.
