Skeleton key proofing unlocking device and electronic lockset

The utility model belongs to the technical field of locksets, and provides a skeleton key proofing unlocking device and an electronic lockset. The device is independent of a lock pin and a key, and is provided with an electronic part and a mechanical part. A microprocessor can send signals to control a mechanical key to open the door only if an electronic key is verified to be correct by the electronic part. Otherwise, the aim of invalid unlocking by changing the lock pin and the key can not be realized under any other conditions, thus, the device truly prevents the invalid unlocking with a skeleton key. Meanwhile, the device is independent of the lock pin structure and is delicate in structure, thus, the device can be widely applied on the lock bodies of various electronic locksets. In addition, the device performs electronic identity verification at first, thus, the device can be taken as the emergency unlocking manner of an electronic lockset.
