Master Lock 5423D – Frequently Asked Questions

1) How big is the inside of the Master Lock 5423D wall mount lock box, and how many keys will it hold?
The internal cavity of the 5423D measures 3-1/2 in (89mm) H x 2-1/4 in (57mm) W x 1 in (25mm) D. That depth is what matters if you're stacking more than one key: the cavity is sized so multiple keys won't jam the mechanism when the door opens. A standard house or deadbolt key with a plastic head fits easily; a fat transponder fob is where 1 inch of depth gets tight.
2) Is the Master Lock 5423D a wall mount box or one that hangs on a door handle?
Wall mount, permanently installed. The 5423D is fastened to a wall or frame and stays there, so it's the format for a rental you turn over repeatedly or a service door crews access week after week. If you need something you can hang on a doorknob and take with you between properties, a shackle-style portable lock box is the other format to look at.
3) Can I set my own code on the Master Lock 5423D push button lock box?
You set the combination yourself, and you can use up to 12 characters, letters, numbers, or a mix of both. The keypad is laid out like a telephone keypad in alpha/numeric format, which is why a word works as well as a number. For a property manager rotating access after a tenant or a contractor leaves, that reset is the whole point of the push button format.
4) Will a Master Lock 5423D push button lock box hold up mounted outdoors in winter?
It carries a protective weather cover over the keypad, which is there to keep the buttons from freezing or jamming. That's the failure people hit with outdoor boxes: ice in the keypad and nobody gets in. The body is molded and the shackle is vinyl coated, so it won't scratch the siding or door it's mounted against.
5) How much wall space does the Master Lock 5423D take up once mounted?
Figure 4-5/8 in (11.7cm) tall by 1-3/8 in (7.9cm) wide for the body. It's a narrow footprint, so it fits on a door frame face or a narrow brick pier next to an entry without crowding the trim.
6) Is the Master Lock 5423D rated for commercial use or is it a residential box?
Master Lock classes the 5423D as residential. For a single rental unit, a homeowner's spare key, or a small landlord's turnover, that's the right tool. Institutional and MRO buyers standardizing key control across a facility, or anyone needing a graded commercial key cabinet, should be specifying up from this one.
7) Can someone read the buttons on the 5423D lock box at night?
The 5423D uses oversized buttons specifically so the code can be entered in low light. It's a real consideration for a box mounted at a back entry or an unlit service door, where a dial-style combination lock box is close to unusable after dark.
8) What model number do I order for the Master Lock 5400 Series wall mount push button lock box?
Model 5423D, part of Master Lock's 5400 Series lock box line. One configuration, so there's no finish or size choice to specify on the order.
