Every company ranked on this page serves Massachusetts and the surrounding area, including Boston, Worcester. Open any listing for its address, phone number and service area, then call the two or three closest to you. Distance is worth checking yourself: the nearest locksmith is not automatically the best one, so this page ranks on rating and review volume first and leaves proximity to you.

After-hours availability is not part of a Google rating, so this directory cannot verify it for you in advance. Being locked out of a house or a car is the case for calling instead of waiting for morning. Call the top rated locksmiths and security companies on this page and ask two things before you agree to anything: are you dispatching tonight, and what is the after-hours call-out fee. A company that answers both plainly on the phone is usually the one that actually shows up.

Use a licensed local locksmith with a real address, not a call center that dispatches a sub and price-gouges on arrival. Get the price on the phone first.
