PROBLEM TO BE SOLVED: To provide an electronic lock system capable of easily changing identification information set to a key. SOLUTION: An electronic key comprises a key body 11 formed of an insulator, and conductive screws 12a-12l, a conductive path 13 and cylindrical conductive members 14a-14f formed of a conductive material. A side face of a stem part 11a of the key body 11 is provided with a plurality of threaded holes 11b. The conductive screws 12a-12l are inserted in all the threaded holes 11b, while the conductive members 14a-14f are inserted only in the predetermined threaded holes 11b, and identification information of the electronic key is composed according to the presence/absence of the conductive members. The electronic lock acquires identification information by checking the conductive state of each threaded hole of the electronic key by a control circuit, and makes an authentication check in comparison with identification information of an authentication key of the same structure as the electronic key.
