He reigned twice: the first time from 1525–1538, and the second time from 1543–1545. During his first reign, which lasted 13 years, he was overthrown by his own son, Saikham. However, Saikham ruled for only 5 years before being deposed by the nobility. Ket was then reinstated to the throne, but ruled for just 2 years before falling into madness and was ultimately assassinated.
