Master Lock 5440D Bluetooth Portable Key Safe – Electronic Lock Box With App Control, Temporary Codes, And Tamper Alerts For Personal Use

About This Product

This Master Lock 5440D is basically a smart lock box that makes sharing keys so much easier.

You can open it with your smartphone via Bluetooth, or use temporary or permanent codes for guests – perfect for letting in dog walkers, cleaners, or Airbnb guests without handing over a physical key.

The app sends you notifications when someone accesses it, and you can even schedule access for specific times.

The removable shackle gives you options, and the big interior holds multiple keys or key cards easily.
It's weather-resistant down to -40°C, so it'll survive outdoors no problem.

Battery life is solid, and it runs on a replaceable CR123A (included).

The Master Lock Vault Home app is free and supports up to 10 locks, but if you need more, you can upgrade to the Enterprise version for business use.
It's sturdy, the coating protects your door from scratches, and it's just super convenient for anyone who needs flexible access control.

Highly recommend for real estate agents, rental owners, or just peace of mind.
