A method for providing a certification service of a lock device using a mobile communication terminal is provided to improve the security of the lock device by using SSD(Share Secret Data) generated by a unique A-Key or a transmission count number. A method for providing a certification service of a door lock device using a mobile communication terminal includes the steps of: in the mobile communication terminal, generating SSD of a terminal side by using an A-Key value(S310); registering the mobile communication terminal at the certification service of the door lock device(S320); checking the information of the mobile communication terminal at a door lock certification server, and generating SSD of a server side(S330); in the door lock device, determining whether the mobile communication terminal tries unlocking(S340); receiving the SSD of the terminal side and the server side from the mobile communication terminal and the lock device certificate server when the lock device determines that the unlocking is tried(S350); comparing the SSD of the terminal side and the server side, and determining whether the SSD of the terminal side and the server side are equal to each other(S360); and in the door lock device, releasing locking when the SSD of the terminal side and the SSD of the server side are equal to each other(S370).
