For eight decades, Southern Lock & Supply has served as a cornerstone of the physical security industry. Founded in 1946 in the home of Bernard and May Cutson, the company grew from a living room to a family garage, eventually establishing its first storefront in south St. Petersburg, Florida. Today, operating from a modern 19,000-square-foot corporate headquarters and multiple Southeast branches in Pompano Beach and Charlotte, North Carolina, Southern Lock continues to honor its deep family roots. Following the 2024 retirement of long-time president David Matthies — who dedicated 59 years of service starting at age 16 — ownership remains proudly in the family under his daughter, Jenell Swartz, and son-in-law, Dave Swartz.

At Southern Lock, we don’t just sell security products; we build lifelong relationships. We treat our locksmith partners like family, proudly serving the children and grandchildren of customers we first partnered with over fifty years ago.

With more than 800 years of combined industry experience, we are a premier wholesale partner for locksmiths across the country. We distribute products from more than 200 manufacturers, housing massive inventories of the industry's most trusted lines, including Allegion, ASSA ABLOY, dormakaba, Master Lock, and NSP. From classic mechanical door hardware to cutting-edge electronic access systems and safes, we are your comprehensive, one-stop shop. If we don’t have a specialized item in stock, our dedicated team will find it for you!
