A latchbolt configured for use with a door lock assembly. The door lock assembly is configured for interaction with a strike coupled to a door frame, and operable to place the latchbolt in a locked configuration using the strike to generally prevent rotation of the door and an unlocked configuration to allow rotation of the door. The latchbolt includes a first member and a second member movably coupled to the first member. When the latchbolt is in the locked configuration the second member is movable relative to the first member from a first position to a second position in response to a predetermined force applied to the door.
