This did not change the club's fortunes, however, as Kilia was unable to overtake its rival and make it out of regional league play to the national level.

After the formation of the Bundesliga, Germany's first top flight professional league in 1963, and the subsequent re-organization of the lower divisions, Kilia found itself in what was now the third tier Amateurliga Schleswig-Holstein.

They took part in promotion playoffs for the Regionalliga Nord (II) at the end of the 1964 season, but were unsuccessful in their bid to move up.

A first place Landesliga finish in 1984 returned Kilia to the Verbandsliga Schleswig-Holstein for a ten-year span until re-structuring made the league a fifth division circuit.
