Master key systems in Fall River, MA
A master key system in Fall River, MA pins every lock in a building so it opens with its own key and with one or more higher-level keys, such as a manager’s master key. It suits offices, mill buildings, stores and apartment buildings. A documented system is an estimated $300–$800+, depending on doors and key levels.
01 /Signs you need one
Do you need a master key system?
If your key ring keeps growing, a master key system is probably overdue.
02 /How it works
How is a master key system built?
A good system starts on paper, not at the door.
Access plan
Who needs to open which doors. This becomes the key schedule: a chart of every key level and every lock.
Pinning
Each cylinder gets extra master pins so it opens with its own change key and the higher-level keys above it.
Key control
A restricted keyway stops unauthorized copies. Keys are stamped and issued against a record.
Documentation
The key schedule is kept so future rekeys and added doors fit the system instead of breaking it.
03 /The process
How a master key project works
Access Plan
List the doors, the people and who needs what. Photos of the existing locks show what can be reused.
Design & Quote
You approve a key schedule and an estimated price before any cylinder is touched.
Pin, Cut, Stamp
Cylinders are re-pinned or replaced, keys are cut and stamped, and each door is tested.
Hand Over
You receive the keys, the key schedule and an itemized invoice.

05 /Example layout
What does a master key system look like in practice?
A simple example for a three-family building with a shared basement.
| Key | Opens | Held by |
|---|---|---|
| Unit 1 key | Unit 1, front entry, back hall | Tenant in unit 1 |
| Unit 2 key | Unit 2, front entry, back hall | Tenant in unit 2 |
| Unit 3 key | Unit 3, front entry, back hall | Tenant in unit 3 |
| Basement key | Basement and laundry | Owner and maintenance |
| Master key | Every door in the building | Owner or property manager |
Every extra key level adds combinations to each lock, which slightly reduces security. A good design uses only the levels a building needs.

Master keying Fall River mills, offices and multi-families
Fall River’s converted textile mills house dozens of tenants behind shared entrances, stairwells and freight doors. Master key systems let the building owner open everything, each tenant open their own suite and the common doors, and nobody open a neighbor’s space.
Multi-family owners use the same idea on a smaller scale: one key per tenant that also opens the front and back doors, and a master key for the owner.
Older buildings often have a mix of lock brands collected over the years. Mixed brands can be standardized with new cylinders as part of the project.
