The Puroma Key Lock Box combines portability and secure mounting options. It ships with a removable lock shackle and a wall-mount kit, so users can hang it on a door knob or secure it to a wall with screws and expansion plugs.

It’s a practical, centralized solution for real estate teams or facilities managers who need organized key storage.

Buying Guide: Key Considerations For Small Lock Boxes
- Installation flexibility: Do you prefer wall mounting, door-hanging, or portable use? Check if the model includes screws, plugs, or a removable shackle.
- Security features: Look for high-durability materials (aluminum alloy or steel), weather-resistant finishes, and a resettable four-digit code with many possible combinations.
- Capacity: How many keys do you need to store? Cabinets with 20 positions suit offices; compact boxes hold 2–5 keys well for homes or rentals.
- Indoor vs outdoor use: Outdoor boxes should have weatherproofing, corrosion resistance, and a protected shackle or shutter design.
- Ease of use: A simple reset process and clearly labeled dials help non-technical users access keys quickly when needed.
- Maintenance and durability: Consider materials that resist hammering, sawing, and prying, plus surfaces that won’t scratch doors or walls.
