1. A deadbolt assembly comprising:
a latch assembly configured to be mounted at least partially within a bore of a door, the latch assembly including a cam and a bolt, the cam configured to move the bolt between at least an extended position and a retracted position;
a first assembly having a first escutcheon configured to be mounted at the bore of the door;
a second assembly having a second escutcheon configured to be mounted at the bore of the door;
a first torque blade extending between the first escutcheon and the second escutcheon within the bore of the door and rotatable around a first axis via at least one of a lock actuator and a turn-piece, the first axis coaxial with the at least one of the lock actuator and the turn-piece, wherein the first torque blade is disposed beneath the latch assembly in the bore of the door;
a second torque blade extending from the second escutcheon, the second torque blade rotatable around a second axis offset from the first axis and passing through the cam of the latch assembly; and
a geared arrangement supported on the second escutcheon and coupling rotational movement of the first torque blade to rotational movement of the second torque blade such that rotation of the first torque blade drives movement of the bolt between the extended position and the retracted position.
