Killeen Machine Tool Company was originally established in 1924. In 1983, Norman Doucet brought Doug Maston on board and together they created Killeen Security Products in Worcester, Massachusetts. Within a year of its concept, KSP shipped its first order.

Now, over 40 years later, KSP has grown into a family-owned manufacturer with a strong reputation in the security industry, producing precision lock hardware and quality lock cores that can be found around the world.

In 2002, Norman’s son, Gene, joined KSP’s operations and helped advance the company through innovation and hands-on manufacturing experience. Starting with operating one of the company’s first CNC mills and personally pinning lock cores by hand, Gene has played a key role in modernizing KSP’s manufacturing processes and implementing new automation technologies that continue to improve efficiency and quality. Both Norman and Doug have since passed away, but we believe they would be proud of the legacy KSP continues to build and carry forward.

In 2020, KSP moved to Auburn, Massachusetts. In our new facility, we continue to manufacture the best quality products for our customers.​Whatever levels of complexity your business requires, your security and satisfaction are our foremost concerns.
