I wasn’t so happy with the service I received from SURE LOCK & KEY when they installed new locks in my dormitory, but when I called them about it, they came out almost immediately and realized the locks had a manufacturing defect. They quickly replace them and didn’t even charge me anything for the second callout… wish all other companies cared about their customers the way these guys do!

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.
