A lock and latch assembly that is to be installed on a door. The assembly has inner and outer actuators, and a latch with a tongue that is movable between an extended position 5 and a retracted position. The tongue is displaceable by rotation of either inner or outer actuator. The assembly has a first lock cylinder with a keyed barrel, and a deadbolt that includes a bolt. The first lock cylinder is operable to displace the bolt between an extended position and a retracted position. A snibbing mechanism includes an inner portion that includes a manually operable snibbing actuator, an outer portion that has a 10 first outer hub that is rotationally fixed to the outer actuator, a second outer hub that is rotationally fixed to the barrel of the first lock cylinder, and an outer slide plate. The first outer hub and outer slide plate have complementary engaging members, wherein the outer slide plate is movable between a free position, and a blocking position in which rotation of the outer actuator is prevented. An intermediate drive connects the inner 15 portion to the outer slide plate. The snibbing actuator is operable to cause the snibbing mechanism to transfer a movement from the inner portion through the intermediate drive to the outer slide plate so as to move the outer slide plate into the blocking position. The outer slide plate is movable from the blocking position into the free position by a rotation of the barrel of the first lock cylinder that causes the deadbolt mechanism to move the bolt 20 from the extended position to the retracted position.
