COMPLEX KEY STRUCTURE FOR CONTROLLING DOORLOCK

摘要

Disclosed is a complex key structure for opening and closing a door lock. The complex key structure for opening and closing a door lock comprises: a digital key consisting of an RFID chip and an RFID antenna; a mechanical key made of a steel material; and a housing which is molded with a plastic material to accommodate the digital key and the mechanical key. The complex key structure allows the door lock to be unlocked or switched to a locked state by separating one area of the complex key using the mechanical key when the door lock is not released from or switched to the locked state due to a trouble concerning power supply of the door lock or the like.
