Interchangeable Door Locks

Killeen Security Products (KSP), manufacturer of Small Format Interchangeable Cores, Mortise and Rim Housings, is located in Worcester, Massachusetts, and has been in New England since 1983. After more than 30 years of continuous service, KSP has built a strong reputation in the security industry. We are very proud to say that all of our products are made in the USA, but they can be found in effective operation all over the world.

KSP manufactures over 15 different keyways for the Small Format Interchangeable Core products that are interchangeable with Best, Arrow and Falcon. We have key blanks available for every keyway we supply. KSP manufactures Mortise housings that have both the staked-on and screw-on cams available. Recently, we have added a Large Format Housing to KSP's line that accepts the "Schlage" large format cores. We supply locksmith tools such as capping blocks, housing wrenches and staking tools.

KSP can assist your company in setting up keying systems that will provide the utmost security for your business. We can implement systems for all levels: from something as simple as keying alike to a Control Key to something as complex as a Great Great Grand Master Key system. We can combine cores to fit all of your needs, as well as maintain the relevant records.

At KSP, customer service is second to none.
