The invention discloses a remote control method and system of an electronic lock. The method particularly comprises the following steps that a configuration file is edited on an intelligent terminal, and the edited configuration file is stored in a cloud server, wherein the configuration file comprises a control corresponding relationship between a user and the electronic lock, and a user right and authentication detection mode; the intelligent terminal receives an electronic lock remote control request instruction of the user and sends the electronic lock remote control request instruction to the cloud server; the cloud server sends an authorization input instruction to the intelligent terminal; the intelligent terminal feeds back an authorization instruction input by the user to the cloud server, wherein the authorization instruction comprises to-be-controlled electronic lock information, control right and an authentication password; the cloud server authenticates the authorization instruction according to the configuration file, and if the authorization is successful, a corresponding execution instruction is transmitted to the electronic lock via a wireless network. By applying the remote control method and system of the electronic lock, under the condition of not changing the physical structure of the electronic lock, the user controls the electronic lock remotely by the intelligent terminal via accessing Internet wirelessly, and the remote control method and system are diversified in application, good in user experience and high in safety.
