A lockable sash assembly for installation on a window assembly is provided. The window assembly includes sashes movable relative to each other to open and close the window assembly when the lockable sash assembly is in a window-openable condition and substantially unmovable relative to each other when the lockable sash assembly is in a window-unopenable condition. The sash assembly includes a sashlock having a rotating device (such as a lever-controlled cam) which is movable between a window-openable position and a window-unopenable position. The sash assembly also includes a locking device which is convertible between a locked state whereat the rotating device is blocked from moving from the window-unopenable position to the window-openable position and an unlocked state whereat the rotating device is unblocked from moving from the window-unopenable position to the window-openable position.
