• a driving rod rotatably capped within the inner barrel, the driving rod has a second lock structure disposed on one end of an outer surface of the driving rod;
• and
• an outer barrel having a first end and a second end opposite to the first end, the second lock structure is exposed by the second end of the outer barrel;
• when the dual key lock core is in a locked state, the lock core rod and the driving rod engage with the outer barrel, the rotation of the lock core rod and the driving rod relative to the outer barrel are restricted;
