The user can send the authorization code to the control end through the Bluetooth module, so that when the insertion end 141 is inserted into the lock core head module 11, the power supply in the passive key 14 can drive the control module and the drive motor 10. When the authorization code input by the input end 142 of the passive key 14 is correct, the control module can control the drive motor 10 to work and unlock. Through the arrangement of the scheme of this embodiment, when the internal power supply module is powered off or has no power, the lock can be unlocked by the passive key 14, and the passive key 14 can be used as an emergency key. The lock core head module 11 here is directly connected to the control module and the drive motor 10, so that when the insertion end 141 of the passive key 14 is inserted, it can be powered by the power supply of the passive key 14.
