A locking arrangement has a plurality of cylinder locks having a cylinder core (14) in an outer core (13). The cylinder core (14) can be actuated by rotation by means of a master key or a suitable individual key (16'). The outer core (13) is rotatably supported in a cylinder housing (12). Spring-loaded tumbler pins (21a to 26c) which are divided into different segments (a, b, c) are arranged in the cylinder housing (12), the outer core (13), and cylinder core (14). In order to increase the security of the locking arrangement, the outer core (13) only extends over a partial length (34) and accordingly over only some of the spring- loaded tumbler pins (23a to 26c), while the rest of the spring-loaded tumbler pins (21a to 21c) are covered by an auxiliary outer core (13') which can be rotated together with the cylinder core via an individual key (16'). This individual key (16') has a rib (32') on its back which is shorter than that of the respective master key. The auxiliary outer core (13') has a continuous slot (31') for the engagement of the rib (32') and the rib (32') of the individual key (16') extends at most until the inner end (35) of the auxiliary outer cylinder (34').
