KeyGuard SL-500 Black
Score: 75/100Rankings
The KeyGuard SL-500 is a portable punch-button lock box with a spacious interior and alphanumeric keypad for flexible code creation. Its main limitation is a somewhat complex setup process requiring precise button rotation. It is ideal for realtors and property managers needing temporary, portable key access.
The Master Lock 5401D is a heavy-duty, wall-mount lock box designed for the secure, permanent storage of multiple keys. It offers reliable mechanical access but lacks modern features like backlighting or smart connectivity. It is ideal for users needing permanent, weather-resistant key storage at fixed locations.
