The key information and new key information are transferred from the portable terminal to the electronic lock, and when the key information transferred from the portable terminal to the electronic lock matches the key information recorded in the electronic lock, the electronic lock is unlocked. When the key information expires, the key information recorded in both the electronic lock and the server are overwritten with “K//n+1.”
