A lock includes a case receiving a driving device having a driving member. A connecting member is connected to the driving member to move therewith. The driving device can be actuated to move the connecting member between upper and lower positions to control alignment of a distal end of a locking member and a passageway of an unlocking member. A first detecting member is mounted in the case and operatively connected to the connecting member. A second detecting member is mounted in the space and connected to a burglar alarm system. When the distal end of the locking member is misaligned with the passageway, the first detecting member is in a conductive state and turns on the burglar alarm system. When the distal end of the locking member is aligned with the passageway, the first detecting member is in a non-conductive state and turns off the burglar alarm system. |
