Master Lock Lock Boxes: Trusted Key Security for Every Application

When it comes to controlling access to your property without hiding a spare key under a doormat, few names carry the credibility of Master Lock. Their lineup of lock boxes spans everything from straightforward combination dial models to app-connected Bluetooth safes, making it easy to find the right solution whether you’re a homeowner, landlord, property manager, or real estate professional.

A Range of Lock Box Styles to Match Your Setup

Master Lock offers lock boxes that can be installed directly on exterior walls or over doorknobs with removable handles and cables so you can conveniently move them from property to property. Options include key safes with dials, push buttons, and Bluetooth access. This versatility means you’re not locked into a one-size-fits-all approach.

• Wall Mount Models: Wall mount designs give you a secure, permanent installation with spacious interiors that hold multiple keys without jamming, plus a weather cover that shields the dials from freezing and grime.
• Portable Models: Portable key lock box designs offer removable "over the knob" installation, and you can set your own four-digit combination lock for keyless convenience and increased security.
• Bluetooth Models: Master Lock offers Bluetooth lock boxes for keys. With the Master Lock Vault Home and Master Lock Vault Enterprise apps, you can manage these connected key safes from anywhere — easily monitoring access and providing or revoking access for other users from your mobile device at any time.
• Push Button Models: Models like the 5423D feature a push-button combination interface, offering quick and tactile entry without needing to align spinning dials.

Built to Withstand the Elements

Master Lock key safes are constructed with solid metal bodies and protective covers to protect from the elements and tampering, and many allow you to choose your own combination or reset the combination as needed. Lock box shutter doors protect combination dials from weather, dirt, and grime, while molded bodies and vinyl-coated shackles prevent scratching. For portable applications, some models include a 24-in steel tether cable to affix and never lose your key.

Who Uses Master Lock Lock Boxes?

These lock boxes are ideal choices for protecting and sharing access to residential properties, short-term rental properties, and managing access to real estate listings. Lock boxes are the easiest way to store and share house keys with the people who need them, while securing them from those who don’t. From Airbnb hosts to property managers juggling multiple units, the ability to grant or revoke access quickly — especially via the Vault app — is a genuine operational advantage.
