BEST

BEST Access Systems traces its origins to 1925 when Frank Ellison Best founded Best Universal Lock Company in Seattle, Washington. Best invented the original interchangeable core, patented in 1921, which revolutionized keying systems for commercial buildings. The company relocated to Indianapolis in 1938 and built a reputation as a premier provider of high-quality mechanical access solutions. Now owned and operated by the dormakaba Group, BEST continues to manufacture interchangeable cores, masterkey systems, cylindrical locks, mortise locks, exit devices, and electronic access control products trusted by commercial, institutional, and government facilities worldwide.
