A rotating modular arm with two arm segments is used in a cabinet locking system. The two arm segments are urged apart by a spring. Each arm segment is connected to a lock bar. When the modular arm is rotated, the arm segments displace the lock bars to lock or unlock the drawers of the cabinet. One of the arm segments defines an elongated asymmetrical slot with two slot portions. The first slot portion is elongated and has a width that is less than the diameter of the second slot portion. A keyed lock housing includes a rotating lock core attached to a Z-shaped crank. A retainer is securely attached to the crank. The retainer has a diameter that is less than the diameter of the second slot portion, but the retainer diameter is greater than the width of the first slot portion. During installation, the retainer is engaged with the modular arm by first inserting the crank through the second slot portion. The crank is then displaced to engage the crank with the first slot portion so that rotation of the lock core will turn the crank and rotate the modular arm to displace the lock bars. A clip is not required to secure the crank to the modular arm. The two arm segments are connected with a releasable detent. A spring mounted on the exterior of one of the arm segments is used to urge the arms apart.
