He then served as a coach for the Haitai Tigers (now Kia Tigers) in 1994–1995 and managed the Ssangbangwool Raiders from 1996 to 1999. After a few brief coaching stints, he managed the LG Twins in 2002, reaching his first Korean Championship Series, which he lost.

In 2005, Kim Sung Keun went to Japan as a bench coach for the Chiba Lotte Marines and later returned to South Korea, where he achieved the most success of his career, leading the SK Wyverns (now SSG Landers) to three championships in 2007, 2008, and 2010, reaching the 1,000-win milestone in 2008.
