Puroma Lock Box Large Key Lock Box - Portable Resettable Combination

In this review of the Puroma Lock Box, the bottom line is simple: this large, portable key safe is best for homeowners, landlords, and service providers who need a secure, weather-protected place to store spare keys for emergency access. The standout reason to buy is the combination of a roomy interior and a resettable 4-digit code that gives up to 10,000 possible codes, making it convenient to share access without handing over physical keys. Install options and a sturdy aluminum and reinforced steel shell make it useful for both wall-mounted and hanging use.

Key Features

• Dual installation: The removable shackle lets you mount the box on a wall or hang it on a door handle for flexible placement.
• Large capacity: The interior holds multiple house keys and card keys so you can leave a spare for guests or service workers.
• Resettable combination: The 4-digit code is easy to remember and reset, offering up to 10,000 code combinations for secure shared access.
• Durable construction: A shell made from aluminum alloy and reinforced steel helps protect the contents from physical tampering.
• Weather protection: The protective door shields the lock mechanism and keys from dust and rain, making it suitable for outdoor use.

Who It's For

The Puroma Lock Box is aimed at homeowners, Airbnb hosts, landlords, cleaners, pet sitters, and realtors who need a simple, portable way to provide access without duplicating keys. Its wall mount and hanging options suit multi-unit buildings as well as single-family homes.

People who need to store very large key fobs, bulky truck remotes, or a large bundle of hardware should look elsewhere, since some users report the size can be tight for oversized fobs despite being larger than many compact models. Those seeking an electronic or remote-access solution should consider a different product.
