Master Lock Co 5423D Push Button Lock Box 3-7/8 in

Product Description

The MASTER LOCK CO 5423D is a portable, wall-mountable push button lock box designed for keyless key storage in residential and light commercial applications. The metal body measures 3-7/8 inches wide and is built for durability in outdoor or exposed installations. A user-set 4-character combination provides keyless access and eliminates the need for a keyed lock mechanism. A protective weather cover shields the push button mechanism from freezing and jamming, making the unit suitable for year-round exterior use. Licensed contractors, property managers, and service professionals commonly deploy this type of lock box to control key access at job sites or service locations.

The 5423D is suited for wall-mounted permanent installation at residential entry points, rental properties, commercial service panels, or anywhere controlled key access is needed without a fixed keyed system. The push button combination design allows access codes to be changed by the installer or end user without special tools. Its portable form factor also supports temporary placements where a permanent mount is not required.

Installation Notes

Installation is typically performed by a general contractor, property manager, or qualified service professional.
