Massachusetts is one of fewer than 20 states that requires locksmiths to hold a government-issued license. Under MGL Chapter 147, Section 29A, all practicing locksmiths in the Commonwealth must be licensed through the Massachusetts Division of Professional Licensure.
Unlicensed locksmith activity is illegal and can result in fines and criminal penalties. Always verify licensure before hiring through the state's eLicensing Consumer Affairs portal at elicensing.mass.gov.
Boston's competitive market includes some fraudulent operators who advertise low prices online but charge excessive amounts at the door. A licensed locksmith means the professional has passed a background check and meets the Commonwealth's competency standards.
Boston locksmith rates are higher than the national average due to the city's cost of living. Prices vary by service type, lock grade, and neighborhood. These are typical ranges from licensed MA locksmiths.
| Service | Typical Boston Range | Notes |
|---|---|---|
| Residential lockout | $95-$175 | Varies by lock type and time of day |
| Deadbolt installation | $100-$250 | Higher for high-security Grade 1 locks |
| Lock rekeying (per lock) | $50-$100 | Multi-lock discounts often available |
| Car lockout | $125-$225 | Luxury vehicles may cost more |
| Transponder key programming | $175-$350 | Dealer alternatives often cost more |
| Smart lock installation | $150-$350 | Includes setup and app configuration |
| Commercial access control | $300-$1,200+ | Per door; complex systems higher |
| Residential rekey (full home) | $150-$400 | Depends on number of locks |

Four steps to hiring a qualified, licensed locksmith in Massachusetts and avoiding common scams.
Use Google Maps to search "locksmith Boston" and look for businesses with established review histories. Avoid listings with only a single address and no website.
Go to elicensing.mass.gov and search by the company name or license number. Confirm the license is active and matches the business you plan to hire.
Before the technician begins any work, ask for a written or verbal price quote that includes labor, parts, and any service call fee. Do not accept vague pricing.
Ask the technician to show their MA locksmith license card and a photo ID before letting them work on your property. A legitimate locksmith will not hesitate.
Boston renters and condo owners increasingly consider smart locks. Here is how they compare to traditional deadbolts in the Greater Boston context.
Boston brownstone note: Many historic properties have non-standard door preps. Have a licensed MA locksmith assess compatibility before purchasing a smart lock.
Feedback from Greater Boston residents who used this guide to find and hire a licensed Massachusetts locksmith.
"I used the licensing verification tip from this guide before hiring a locksmith in Beacon Hill. Checked elicensing.mass.gov, confirmed the license was active, and had a great experience. No surprise charges, professional work."
"The cost breakdown was incredibly helpful. I was quoted $340 for a basic rekey and knew from this guide that was about double the fair rate. Found a licensed locksmith who charged $85 for the same job. Saved over $250."
"Had a car lockout in Cambridge. The guide's advice to get a quote over the phone before the locksmith arrives saved me from a bait-and-switch. The licensed tech I found was at my car in under an hour."
"Managing a Somerville rental property. The commercial locksmith section helped me understand master key systems and access control. Set up a proper system for our 12-unit building. Worth every penny."
