Organized Access Without Carrying Dozens of Keys

Master Key Systems in Springfield and surrounding towns for managing multi-unit buildings where tenants and maintenance staff need different levels of entry

A.W. Gifford Inc designs and installs master key systems in Springfield, throughout Western Massachusetts, and Northern Connecticut for apartment buildings, office complexes, and institutions that require controlled access across multiple doors. Allowing a property manager to carry one master key while tenants or employees carry individual keys that only open their assigned spaces.


The system works by pinning each lock cylinder in a way that allows two or more keys to operate it. A master key opens all locks in the system, while a change key opens only one or a subset of doors. This is common in office buildings where a supervisor needs access to multiple departments but individual staff members only enter their own offices. Restricted key systems are exclusively supplied by Gifford's with keys duplicated in-house. No other locksmith in the Northeast has access to our proprietary key blanks, and all duplication requests require authorization through our signature verification system. This ensures you maintain true control.


If your building needs a new master key system or you want to update an existing one, schedule a consultation to review the layout and determine the keying structure.

How a Master Key System Is Structured

Your locksmith begins by mapping out every door in the building and assigning a hierarchy of access. Locks are then pinned to accept both a change key and a master key. In more complex systems, a grand master key may be added to allow access to multiple buildings or floors, with sub-masters controlling specific zones.


Once the system is installed, you will be able to issue keys based on role and responsibility, and each key will only open the doors it is authorized for. A.W. Gifford Inc maintains records of the keying schedule so that if a lock needs to be added or a key is lost, the system can be expanded or adjusted without replacing every cylinder.


Existing master key systems can be maintained and expanded as tenants change or new doors are added. If a key is lost or you need to restrict access for a former employee, individual cylinders can be re-pinned without affecting the rest of the system, though this depends on how the original keying was structured.

What You Should Know Before Installing a Master Key System

These questions come up when building owners or facility managers in Springfield and surrounding areas are evaluating whether a master key system is the right solution for their property.

What is the difference between a master key and a change key?

A master key opens all locks in the system, while a change key opens only the specific lock or locks it is assigned to.

How do you prevent unauthorized duplication of master keys?

Restricted key systems use patented key blanks that are not available at retail stores and require authorization from the property owner to duplicate.

Can you add new locks to an existing master key system?

Yes, as long as the locksmith has the original keying schedule and the system was designed with expansion in mind, new locks can be pinned to fit into the hierarchy.

What happens if a master key is lost?

If a master key is lost, the entire system is compromised and may need to be re-keyed or re-pinned to restore security, depending on the level of risk and the number of doors involved.

Why would a business in Springfield need a master key system instead of individual locks?

A master key system reduces the number of keys that supervisors or maintenance staff need to carry while still allowing individual employees or tenants to have limited access.

If your building has more than a few doors and you need to manage who can enter each space, reach out to A.W. Gifford Inc to discuss keying options and whether a restricted key system is appropriate for your security needs.
