Illinois Lock Company was founded in 1930 on Taylor street on the west side of Chicago. The company spent 30 years there before its move to our current location in Wheeling, Illinois in 1960. In 1965 Illinois Lock was purchased by The Eastern Company. The Eastern Company is a 140 year old manufacturer of proprietary locks and other security devices with seven manufacturing locations in the U.S.A., Canada, Mexico and the Pacific Rim.
