Abstract

A deadbolt assembly includes a bolt housing having a longitudinal sleeve defining a first axis. A bolt is located in the longitudinal sleeve. An elongate member has a first end and a second end portion opposite the first end, the first end being attached to the proximal end of the bolt and the second end portion having a first connector. A rotatable crank has a pivot member, a second connector and an arm. The second connector of the crank is operationally engaged with the first connector of the elongate member. A first actuator assembly has a body, a lock cylinder, and a tailpiece that extends from the lock cylinder and is rotatable around a second axis with respect to the lock cylinder. The tailpiece is engaged with the pivot member of the crank. At least a portion of the lock cylinder extends past a vertical plane of an outer side surface of the elongate member.
