a housing configured for mounting to a door;

a latchbolt mounted in the housing for axial movement along a longitudinal axis between a projected position and a depressed position relative to the housing;

a roller engaged with the latchbolt such that the axial movement of the latchbolt from the projected position to the depressed position engages a drive surface of the latchbolt against the roller to urge the roller from a first position toward a second position; and

a locking sleeve movably mounted to the housing for movement relative to an axis via one or more actuators, the locking sleeve having at least one recess operable to partially receive the roller, and the locking sleeve having a blocking surface operable to engage the roller to prevent movement of the roller from the first position to the second position;

wherein the locking sleeve is displaced relative to the axis between a locking position in which the blocking surface is aligned with the roller and engages the roller to prevent movement of the roller from the first position to the second position and thereby retain the latchbolt in the projected position, and at least one unlocking position in which the at least one recess is aligned with the roller to permit movement of the roller from the first position to the second position and into the at least one recess to thereby enable depression of the latchbolt; and

wherein the locking sleeve is rotatably mounted to the housing for rotation about the axis via the one or more actuators, wherein the locking sleeve rotates about the rotational axis between the locking position and the unlocking position, wherein the one or more actuators comprises a motor including a shaft coupled with the locking sleeve and a body portion operable to rotate the shaft, and wherein rotation of the shaft by the body portion moves the locking sleeve between the locking position and the unlocking position.
