The present invention provides a door lock / unlock system employing a combination of fingerprint authentication and password authentication, which enables the use of a user who is unable to register a fingerprint and at the same time a visitor who does not have a fingerprint registration using a password. The control method is related.;The present invention comprises the steps of starting the system in conjunction with the user to open the fingerprint input cover or the keypad cover, and when the user opens the fingerprint input cover to input the fingerprint to the fingerprint input pad performs fingerprint authentication according to the fingerprint processing routine and If you open the keypad cover and input the start button and the number button, if the entered number is more than the set digits, the entered number is authenticated according to the password processing routine, and the entered number is the same digit as the set digit. In case of, recognize the input number as the user's identification number and perform authentication according to the user's identification number and fingerprint according to the subsequent input of the user's fingerprint, and if the authentication is successful, drive the actuator to lock the door By retracting the king member, the door is set to the unlocked state and the user is informed of the authentication result. It is characterized by consisting of a step.
