PURPOSE: A method for double-locking wireless door lock is provided to eliminate the inconvenience of using the door lock and to improve safety thereof by enabling the wireless door lock in the first locking state to be operated in the second locking state or release state. CONSTITUTION: If the door lock is in the release state and a prescribed time period has elapsed, a door-locking signal is generated in step(S402), which changes a door lock/release device into the locking state(S403) and maintains the door lock in the first locking state(S404). If the door lock was in the locking state, a determination is made whether the password has entered and the entered password is in accord with the predetermined password(S406). If the entered password is out of accord with the predetermined password for the predetermined number of times, an alarm signal is generated(S409). If the password has not entered, a determination is made whether the start/end key is entered. If so, a CCD monitor is activated for communication with a visitor. If the start/end key has not entered, a determination is made whether the normal emergency key is entered. If not, an alarm signal and the door-locking signal is generated to enable the second lock/release device to be operated in the locking state.
