Portable Key Storage for Home and Vehicle Access
The Master Lock 5400D provides a portable, over-the-door-knob safe that holds up to five keys. Its solid die-cast steel body resists hammering and sawing, while the zinc lock body and weather-resistant shutter protect the mechanism outdoors. A moulded bumper and vinyl-coated shackle prevent surface scratches during use. The grey finish blends with surroundings to minimise attention.
Suits Homeowners and Property Managers Needing
Ideal for households, carers or rental hosts who must grant entry without handing out physical keys. The resettable four-digit combination lets authorised users enter a code they can remember. Not for buyers who require audit trails, electronic credentials or a unit that mounts permanently to a wall or solid surface.
Internal Cavity Accepts Multiple Keys Without
The spacious cavity measures 3.25 in. wide by 7.25 in. high by 1.5 in. deep, accommodating over five standard door or car keys simultaneously. This capacity is the deciding factor: if your key bundle exceeds this volume, the safe will not close securely.

Questions about this item
How do I verify the 4-digit combination I set on the 5400D is working before I leave keys inside?
After setting your personal 4-digit code, scramble the dials, then re-enter the combination; the shackle should release smoothly, confirming the mechanism operates as intended.
What comes in the package and is any mounting hardware sold separately?
The clamshell package contains the 5400D key safe unit only; its over-the-door-knob design requires no extra hardware for portable installation.
Which capacity should I choose if I need to store five standard door or car keys?
This model’s internal cavity is rated for over five keys, so the single 5400D version covers that requirement without needing a larger size.
