STRT

Strattec Security Corp

A maker of automotive locks, keys, and access-control systems, Strattec supplies the parts that let drivers unlock and start their cars. It grew out of the automotive lock division of engine maker Briggs & Stratton, which began making keys and locks in the early 1900s, and was spun off as an independent company in 1995. Its name blends "Strat" from co-founder Stephen Stratton with the security business it kept.
