Family-Owned SecuritySince 1964
Three generations of the Carneval family have built Interstate Security into Erie's most trusted locksmith and security provider. What started as a two-man partnership over 60 years ago is now a full-service operation serving the entire Tri-State Area.
Our Story
From a small lock shop on Erie's east side to a full-service security operation, the Carneval family has been protecting homes and businesses for over six decades.
In 1964, John J. Carneval and Paul Raupers pooled their expertise and opened Car-Paul Safe & Lock Co. in Erie, Pennsylvania. The company name was a combination of their surnames, and the partnership laid the foundation for what would become one of the region's longest-standing security businesses.
Shortly after the founding, Raupers sold his interest, and Mr. Carneval took the reins as sole proprietor. For nearly 40 years, he grew Car-Paul from a small storefront operation into a recognized name in Erie County's locksmith industry, earning the trust of homeowners, businesses, and institutions throughout the area.
In 1976, Carneval identified an opportunity to serve fellow professionals in the trade and established Great Lakes Supply Co., a wholesale locksmith supply business. For over two decades, the two operations ran side by side, each reinforcing the other's reputation for quality and reliability.
On March 10, 1997, Car-Paul Safe & Lock and Great Lakes Supply were officially merged and incorporated as Interstate Security, Inc. The consolidation brought the Carneval family's full range of retail and wholesale capabilities under a single name, positioning the company to serve the growing security needs of the Tri-State Area.
