The invention provides a ball complementary lock. The ball complementary lock comprises a lock body and a cylindrical lock cylinder. The cylindrical lock cylinder is arranged in the lock body and comprises an axially-formed lock cylinder hole and N radially-formed ball hole sets sequentially arranged in the insertion direction of the lock cylinder hole. Each ball hole set comprises two first ball holes oppositely formed on the two sides of the lock cylinder hole. Each first ball hole comprises a small hole and a large hole which are coaxially communicated and the small holes are communicated with the lock cylinder hole. The lock body is provided with multiple second ball holes correspondingly communicated with the large holes one to one. Except for the Nth set, the two first ball holes of at least one ball hole set are correspondingly provided with first ball structures respectively, and the two first ball holes of each of the other ball hole sets are correspondingly provided with a second ball structure and a third ball structure respectively. The ball complementary lock can be better prevented from being pried or technically unlocked.
