1. A lock module for a vertically movable closure, the vertically movable closure having a bottom bar, the lock module comprising:
a housing configured for mounting to or within a bottom portion of a frame, wherein the frame is adjacent to the vertically movable closure;
a lock pawl moveable between an extended position and retracted positions, the retracted positions comprising an upward retracted position and a downward retracted position, wherein the lock pawl is biased towards the extended position by a biasing element coupled to the lock pawl, wherein the lock pawl extends from the housing by a greater distance away from the housing in the extended position than in the retracted positions, wherein the lock pawl is moved by contact with the bottom bar of the vertically movable closure into the upward retracted positon as the vertically movable closure moves from a closed position to an open position and wherein the lock pawl moves into the downward retracted position as the vertically movable closure moves from the open position to the closed position via contact with the bottom bar;
a carriage mounted within or to the housing, the carriage comprising sidewalls that define an open box, the carriage comprising a blocking element configured to be actuated to block the lock pawl from moving from the extended position to the retracted positions, wherein the entire blocking element is configured to move between a first position and a second position along a blocking element path that is along a linear axis defined by horizontal movement of the blocking element along the sidewalls of the open box of the carriage; and
an actuator coupled to the blocking element, wherein the lock module being in a locked configuration when the actuator is activated to move the blocking element from the first position to the second position along the blocking element path to block movement of the lock pawl from the extended position to the retracted positions, which blocks the movement of the vertically movable closure via contact of the bottom bar with the lock pawl.
