What do we strive for as an organization?

To be the global leader in locking security products designed to protect freight and cargo for the transportation industry.

Vehicle Security Innovators, LLC

Vehicle Security Innovators, LLC (VSI) is the parent company to four strategic business units focused on custom security and maintenance solutions for the transportation industry. Located in Green Bay, Wisconsin and originally founded in 1948 as Vandersteen and Sons, VSI’s goal was to provide lock and key services to the locksmith industry. In 1989, our services evolved to assembly of automotive and truck locksets for the domestic OEM production environment. By the end of 2004, VSI became the main supplier of locksets for the North American Heavy Truck market. In 2011, VSI acquired Pop & Lock, the industry leader in aftermarket tailgate lock solutions for pick up trucks. Then in 2013, Freight Defense was started, whose mission is to protect medium and heavy duty fleets and owner-operators with innovative security products designed to minimize theft, improve safety and keep freight moving.
