His original given name was Hyogi, his pen name Baekchon, and his posthumous title Chungui. Beginning as an editor (geomyeol) in the Office of Royal Decrees (Yemun-gwan), he passed through many offices to become Minister of Works concurrently serving as Three-Armies commander (samgun dojinmu).
When King Sejo usurped the throne in 1455, he secretly plotted with Seong Sam-mun, Bak Paeng-nyeon, and others to restore King Danjong, but the plot was discovered and he died a martyr.
In 1791 (15th year of King Jeongjo), he was included as one of the Three Loyal Ministers (samjungsin) in the Eojeong baesikrok, which honored the officials who died for Danjong, and he received the posthumous title Chungui. Later there were discussions proposing to include him among the Six Martyred Ministers (사육신).
A memorial (empty) grave is set up at Sayuksin Park in Noryangjin, Dongjak-gu, Seoul.
His son Kim Hyeon-seok, while serving as magistrate of Yeongwol, died a martyr together with his father.
