Locksmith license in Massachusetts
The short answer
No statewide licenseNo statewide locksmith license that we could find. Massachusetts has no locksmith board, and the last licensing bill we found (H.3742, 2011 to 2012) didn't pass. A 2025 bill (H.1562) is about notice when locksmiths change locks at rentals, not licensing. Confirm with the Division of Occupational Licensure.

What to do in Massachusetts
We found no statewide locksmith license in Massachusetts. That doesn't mean no rules: you still need whatever general business registration and local business license your city or county asks of any trade, and some cities and counties license locksmiths on their own. Call the city or county clerk where you're based before you open, and check again if you start working in a new county.
Local rules
We didn't find a city or county locksmith license in Massachusetts. Local rules change more often than state law, so ask your city or county clerk.
Every state: ID and proof on every lockout
Whatever the license rules, check a photo ID and proof that the caller lives there or owns the car before you open anything, and keep a record of it. Our lockout authorization form gives you a signed record for the file.
