A method for door lock calibration, a calibration apparatus, a door lock, and a non-transitory computer storage medium are provided. The method for door lock calibration includes the following. A first magnetic-field-intensity numerology at a position of a door in an ajar state, a second magnetic-field-intensity numerology at a position of the door in an open state, and a third magnetic-field-intensity numerology at a position of the door in a locked state are collected. A mapping relationship between the ajar state of the door and the first magnetic-field-intensity numerology, a mapping relationship between the open state of the door and the second magnetic-field-intensity numerology, and a mapping relationship between the locked state of the door and the third magnetic-field-intensity numerology are transmitted to a
database.
