1. An electronically-controlled, manually-actuated lock comprising:
a motor;
an actuating spindle actuatable by the motor and positioned to rotate around a first axis in response to actuation of the motor, the actuating spindle comprising a driving pin that engages a transmission spring such that, upon rotation of the actuating spindle, a position of the transmission spring changes relative to the driving pin along the first axis between a neutral position and a biasing position;
a bezel assembly positioned to rotate around a second axis and comprising a bezel rotatably coupled to a sleeve within which a bore is defined that is operatively engageable by a pin movable between an engaged position, in which the pin partially resides within and extends through the bore and is received in a recess defined in a coupling, and a disengaged position, in which the pin is disengaged from the coupling;
a flange at least partially surrounding the bezel assembly, the pin, and an actuator spring, the flange being engageable by the transmission spring at least when the transmission spring is in the biasing position, the flange being movable between a first position and a second position, wherein:
the flange remains in the first position when the transmission spring is in the neutral position;
the flange is biased toward the second position when the transmission spring is in the biasing position; and
biasing the flange toward the second position compresses the actuator spring, which pushes the pin toward the engaged position; and
a deadbolt latch assembly including:
a latch bolt movable between a locked position and an unlocked position; and
a torque blade rotatably coupled to the coupling and drivably coupled to the latch bolt,
wherein, when the pin is in the engaged position, manual rotation of the bezel around the second axis rotates the torque blade around the second axis and drives movement of the latch bolt from the locked position to the unlocked position or from the unlocked position to the locked position.
