The invention relates to an electronic lock system and a management method thereof. The system comprises electronic locks, door cards, a fixed reader-writer, a hand reader-writer and a management platform. The management method comprises the following steps: the management platform controls the fixed reader-writer to initialize the door cards for setting types and parameters of the door cards; the door locks are initialized and corresponding parameters of the door locks are set; the door cards of various types are used for unlocking the electronic locks or performing other corresponding functional operations, and the electronic locks or the door cards record the operations and store record data; the management platform reads the record data of the door cards by the fixed reader-writer; the hand reader-writer reads the record data of the electronic locks and modifies the parameters of the electronic door locks; the hand reader-writer reads the record data of the door cards; and the management platform reads the record data of the door cards and the electronic locks from the hand reader-writer and writes the parameters of the electronic locks and the door cards in the hand reader-writer, therefore, the effective management of a system with multiple door locks is realized.
