Key Bank has a single branch in Brownstown Township at 23116 Telegraph Road.
This branch opened on August 23, 1976 under the name Erie State Bank, whose well-known slogan was "The Saturday Bank," one of the first banks Downriver to observe regular hours on Saturdays. This branch would last until New Year's Day 1988, when it was acquired by First of America Bank and then later sold to Society National Bank on October 1, 1992. Society would ultimately merge with Key Bank on June 17, 1996. Key Bank has operated this branch since then.
