A lock structure includes a lock cylinder, a plug and a pin assembly, the plug is within an accommodating space of the lock cylinder. The plug comprises an outer lateral wall, a plurality of first lower pin holes and at least one second lower pin hole, each of the first lower pin holes comprises a first blocking edge, the second lower pin hole comprises a second blocking edge, wherein a second depth defined between the second blocking edge and the outer lateral wall is smaller than a first depth defined between the first blocking edge and the outer lateral wall. By height difference between the position of the first blocking edge and the position of the second blocking edge, an unmatched key can not contact with the second lower pin under instantaneous bump to prevent an unlock situation. Therefore, the burglar proof function is achieved. |
