The keystone was laid on August 18, 1972, and the solemn dedication was held February 22-23, 1975. The church's organ came from an old NGK church in Wolseley, Western Cape, also built by Smith, which had to be demolished due to damage from a September 29, 1969 earthquake. The congregation then bought the organ for R3,000 from the Keetmanshoop-Noord church, and their new church, designed by Smith, was built with its own new organ. The firm of Cooper, Gill & Tomkins, based out of Cape Town, rebuilt and modernized the older organ for R10,000. With the reincorporation of Keetmanshoop-Noord into the Keetmanshoop NGK church, as in 1950, there was once again only one church building for the GKSA, which acquired the building for the fair price of N$300,000, less than they had paid for the old church after adjusting for inflation. The dedication of the church into the GKSA was made on November 17-18, 2001. The Mariental Reformed Church and the Karasburg Reformed Church were both spun off from Keetmanshoop in 1966. Karasburg operated joint services with Keetmanshoop and Mariental from 1979 to 2006.
