An electronic lockset structure comprised of key, lock head, lock body, electrical control circuit and key manager. Characterized in that the key is provided with built-in battery and electronic cipher circuit, electrode contactor on the key elastically contacts with electrode contactor provided inside the lock head, and the circuit is linked to the electrical control circuit in the lock body, the electrical control circuit inside the lock starts working, electrically controlled microprocessor decodes and drives the treatment, if cipher fits, the magnetic valve will be attraction-closed and the block is driven to move away with micropower, drawing tooth or groove on the key activates lock bolt in the lock to move, unlocking is accomplished. There is no electric source inside the lock body, and the inserted key supplies power. The key is molding standardly, which is generally serviced with the lock. One key is capable of unlocking a plurality of electronic locks, and one electronic lock can be fitted with multiple keys. The lockset structure of the invention is mature and ingenious, electronic cipher is employed, particularly that electrical micropower driving and key standardization technology are employed, which is simple and reasonable, and is easy to use, it is safe and reliable.
