Locked myself out of my car and needed to get back in. Eric the mobile locksmith came out very quickly after I called and unlocked my car. He even cut me a new key as a spare so it won’t happen again… let’s hope so! Wonderful service though...

I’ve never posted a review online before, but with this company I decided it was worth it as they were just fantastic in replacing locks to my apartment after a break-in. Such nice guys, very understanding, and extremely hard workers too. I’m a satisfied customer!

I googled local locksmiths when I needed a new set of keys cut, and SLK seemed to get really good reviews. I see why now as I called into the New Haven office and had a new set of keys made in less than 30 minutes… wonderful service and such nice people!

About Groton
Groton was settled by Europeans in 1650 as a part of New London. Years later, in 1705 it separated. It got its name after the town of Groton in Suffolk, England. The town lies on the eastern part of the state’s shoreline, between the Mystic River and the Thames River. The land wasn’t suitable for the agricultural industry but the access to the ocean had advantages. The maritime industry played a major role in the town’s life. Whale hunting was the basis of local industry in the 1800s. In 1954 the world’s first nuclear-powered submarine the USS Nautilus launched here.
