Master Lock Co 5424D Light Up Dial Lock Box

Product Description

The MASTER LOCK CO 5424D is a portable combination lock box designed for secure, on-site storage of spare keys and access cards. The unit features large, illuminated dials that allow the combination to be read and entered in low-light conditions. The metal body measures 2-7/8 inches wide, providing a compact yet durable housing. The resettable combination eliminates the need for keys to access the box itself, making it a practical solution for property managers, service technicians, and real estate professionals who need to control site access without issuing physical keys.

This lock box is suited for both residential and light commercial applications. The over-the-door shackle design allows the unit to hang on a standard door handle or similar fixture without drilling or permanent installation. It is commonly used by HVAC technicians, plumbers, electricians, and property managers to leave access credentials at job sites, rental properties, or service locations where multiple trades need entry at different times.

Key Features

• Large, illuminated dials for readability in low-light and nighttime conditions
• Metal body construction, 2-7/8 inches wide, for job-site durability
• Over-the-door shackle mounts on door handles without tools or fasteners
• Resettable combination allows the code to be changed without specialized tools
• Stores spare keys and access cards in a single secure compartment
• Portable design — no permanent installation required

Compatibility

Designed as a portable key-storage solution for residential and light commercial entry points where a standard door handle, knob, or similar fixture is present for shackle mounting.

Installation Notes

No tools or fasteners are required for standard over-the-door installation — loop the shackle over a door handle or comparable fixture and set the combination. When programming a new combination, follow the manufacturer reset procedure before closing the box. Do not leave the box mounted in a location that exposes the dials to direct, sustained impact that could reset the mechanism unintentionally.
