Nashoba Security, Inc., (formerly know as Nashoba Lock) was established in 1968 as a local locksmith company. In 1986, Army Veteran Charles E. Bell, purchased the business and developed it into one of the most trusted security installation & repair companies on the East Coast.

Serving Financial Institutions, Municipalities, Private Companies, State and Federal Agencies, Department of Defense, Medical Facilities, and Real Estate management companies, NSI is no fly by night operation. Having been in business for over forty years, our exemplary knowledge and service has earned NSI a reputation as one of the top security companies in Massachusetts. Our service area includes all of New England and we have recently expanded to a second location in South Carolina. This new location will offer service to South Carolina, North Carolina and Georgia.

Why Choose NSI Security

The Commonwealth of Massachusetts does not regulate the locksmith industry and there are no license requirements to be a locksmith. The result is that the locksmith industry in Massachusetts is riddled with disreputable individuals and companies that use unqualified technicians and substandard equipment. While the customer believes they are getting acceptable service for a reasonable price, they in fact could be getting service from an unqualified technician who is using materials for the project that are second-rate. In these instances, the end result will be higher costs to the customer when another company needs to be called to fix the workmanship and replace the materials used.
