At his retirement in 1989 Keeley held the rank of Career Minister.

At other stages in his career he earned the Superior Honor Award (for Cambodia), a Presidential Citation (for the Refugee Task Force), and a Presidential Distinguished Service Award (for Zimbabwe). In 1985 he was elected President of the American Foreign Service Association.
