Master Lock 5400EC Black
Score: 78/100Rankings
The Master Lock 5400EC is a versatile, portable key safe that offers reliable mechanical security for up to five standard keys. Its primary trade-off is the vulnerability of its shackle to cutting tools and limited capacity for bulky items. It is best suited for realtors and homeowners needing temporary, flexible access solutions.
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.
