A lockset including a bolt mechanism, an exterior assembly, an interior assembly, a driving tailpiece, and a driven tailpiece. The bolt assembly includes a bolt having an extended position and a retracted position. The exterior assembly includes a rotatable exterior manual actuator. The interior assembly includes a clutch having a coupling state and a decoupling state. The driving tailpiece is connected between the exterior manual actuator and the clutch. The driven tailpiece is connected between the clutch and the bolt mechanism such that rotation of the driven tailpiece actuates the bolt assembly. In the coupling state, the clutch couples the driving tailpiece with the driven tailpiece such that the exterior manual actuator is operable to actuate the bolt assembly. In the decoupling state, the clutch decouples the driving tailpiece from the driven tailpiece such that the exterior manual actuator is inoperable to actuate the bolt assembly.

A smart deadlock system according to an embodiment of the present invention includes a thumb-turn, a key cylinder, a connecting shaft connecting the thumb-turn and the key cylinder, and a sensor module. The sensor module may include a sensing unit to sense a rotation state of a rotation sensing element inserted onto the connecting shaft, and generate sensing information associated with the rotation state of the rotation sensing element, and a rotation information generation unit to receive the sensing information from the sensing unit, and generate rotation information associated with an extent of rotation of the rotation sensing element based on the sensing information. According to the smart deadlock system, it is possible to check the operation of the deadlock more accurately by sensing the rotation state of the rotation sensing element using the sensor.

In accordance with an embodiment, electronic control is provided for the locking function of Lift-Handle and T-Handle products, while maintaining desirable mechanical latching mechanism functions and operations.
