Puroma Lock Box Portable Key Lock Box - Secure Wall or Doorknob

In this review of the Puroma Lock Box, the bottom line is simple: it is a practical spare-key solution for homeowners, hosts, and property managers who need secure, weatherproof access without electronic systems. The reviewer found the unit useful because it offers two installation options and a resettable 4-digit combination that balances security with easy sharing of access. For those who value a metal, cut-resistant shell and straightforward setup, this lock box delivers reliable, low-tech key storage for short trips, rentals, or emergency access.

Key Features

• Two mounting choices: The removable cable handle lets it hang on a doorknob or fence while the included screws and expansion plugs provide a secure wall-mounted option for long-term placement.
• Resettable 4-digit combination: The lock uses a four-digit code with 10,000 possible combinations so owners can share temporary access without a key.
• Sturdy construction: Built from aluminum alloy and steel, the reinforced exterior offers protection against hammering and sawing attempts for better durability.
• Weatherproof design: Rust-proof and corrosion-resistant materials mean it can be used outdoors for rental homes or indoor entry storage without rapid degradation.
• Spacious interior: The cavity accommodates multiple house keys or small key fobs so guests or cleaners can retrieve what they need easily.
• Portable cable handle: The cut-resistant handle provides temporary mounting flexibility when wall installation is not desirable.

Who It's For

The Puroma Lock Box is ideal for Airbnb hosts, landlords, and homeowners who need a simple mechanical way to share access with guests, cleaners, or service personnel without giving out a key. It also fits small offices or warehouses that require occasional controlled entry and where a weatherproof, metal box is preferred over electronic solutions.

Those who should look elsewhere include people requiring electronic audit trails or remote access control, and anyone who needs a high-security safe for valuables beyond spare keys. Also, buyers who expect perfect mechanical consistency should be aware some units may require a careful initial setup of the code.
