Mr. Locksmith

Mr. Locksmith is a Woburn locksmith Eli Aharon has run as a sole proprietorship for 19 years. Its Better Business Bureau profile lists a fairly wide scope of lock work — rekeying, deadbolts, patio door locks, master key systems, safes, high security and window locks, new-construction lock work, and car lockouts. The business carries a BBB A+ rating, though it isn't a BBB-accredited business, and that BBB page doesn't show any posted customer reviews or complaint history. Outside the BBB listing, a commenter in an Arlington-area Reddit thread said they've had good experiences working with Eli directly. There isn't much independent customer feedback to go on beyond that single Reddit comment — the BBB grade and Eli's long run in business are the main things to weigh here, so it's worth asking him directly about work similar to yours before booking.
