Key Features of the key lockbox
- Generous Capacity: Holds up to 5 standard-sized keys, perfect for families and property managers.
- Customizable Security: Set any four-digit resettable combination, giving you thousands of unique security box code options for peace of mind.
- Outdoor Durability: Constructed from sturdy metal; shutter door protection keeps the dials safe from rain, snow, and dust while ensuring secure key access.

Real-World Performance Testing
In hands-on trials, the key lockbox delivered reliable performance in outdoor settings, handling rain, wind, and temperature swings thanks to its weather resistant metal construction. The shutter door makes a noticeable difference, keeping the resettable combination dials clean and operable even after extended exposure.
This tool lives up to its promise of secure key access for up to five house or car keys, accommodating standard sizes without a hitch. However, larger or bulky keychains may fit tightly, and users with oversized fobs should measure beforehand. In our tests, code changes were straightforward using the rear switch; it took under five minutes to set up and mount on a brick wall.
The master lock 5401EC design resists everyday tampering, but like most outdoor key storage solutions, high-security threats (like determined lock picking) remain a limitation. For business owners managing several rental units, installing multiple boxes was manageable—each can be given a unique code for extra security.

How It Compares to Alternatives
Compared to similar security box models like the Kidde AccessPoint 001413 and Barska Combination Wall Mount Key Safe, this model from Master Lock stands out for its weather resistant shutter protection and robust build quality. While competitor boxes may offer similar combination lock mechanisms, many lack the same level of all-weather durability or as many personalized code options.
Warranty periods are comparable, with Master Lock known for responsive support. In terms of cost, this device sits in the mid-range between budget generic boxes and pricier Bluetooth models.
Who Should Buy This Product?
This tool is made for homeowners, Airbnb hosts, and real estate agents seeking outdoor key storage that balances convenience and reliability. It’s also an ideal pick for office managers needing secure key access for maintenance staff or shift workers.
However, those needing ultra-high-security protection, like commercial banks or sensitive data centers, may want to consider advanced locking systems. Similarly, if you frequently need to store bulkier items, the compact design may not suit your needs.
