A double system lock apparatus comprises a lock shell, a combination lock, a key lock, and a control piece set. The lock shell has a panel and a main base assembled with each other. The combination lock has a plurality of rotating discs, coupling springs, couplings, and a shaft. The key lock has a lock cylinder and a sleeve set.
