After this he went to Georgia in 1830 where he practiced medicine; establishing a practice in Jasper County and working in some other locations. He married twice with both his wives dying. In 1847 he joined the American forces in the Mexican American War. After the war he went to California where he was for a time a miner in Placerville, California.

A Democrat, Keene was elected to the California State Senate in 1850, representing the 12th district. He would be reelected in 1854 to the 18th district. In the Senate, he was the author of a bill that authorized the Governor of California to procure blocks of marble to construct the Washington Monument in Washington, D.C..
