Amazon Basics Wall Mounted Key Storage Box with Combination Lock (Black) 3.5 x 8.6 x 12 cm

What it is and what it solves

A compact, wall-mounted key storage box designed to keep a key secure yet readily accessible. Its 4‑digit combination lock can be reset as needed, offering a practical solution for professionals and households where keys need to be shared or accessed by trusted people.

How it performs

The lock provides 10,000+ possible combinations, reducing the likelihood of casual guessing. A dedicated cover hides and protects the combination mechanism from elements such as sand, dust and dirt, which helps maintain reliable operation. The unit is crafted from durable aluminium and zinc alloy, giving it a level of ruggedness and rust resistance suitable for everyday use.

Pros and cons

Pros: compact footprint, straightforward resettable combination, protective cover, durable materials, modest appearance in black. Cons: not stated to be weatherproof beyond the protective cover, so outdoor exposure might still require caution, the box is relatively small, so it’s meant for a single or a few keys rather than high-volume key storage.

Who it’s for

This box suits realtors, pet sitters, house cleaners, maintenance workers and households with after-school access needs. If you prioritise a simple, low-profile solution to store one or a few keys securely, it’s worth considering.

When it’s worth buying

If you regularly hand access to trusted people and want a dedicated, removable option that can be mounted on a wall with a straightforward resettable code, this model offers value for money and practical security features. It can be a sensible upgrade from loose-key arrangements.

When to pass

If you need a larger capacity or a unit with explicit weatherproofing for harsh outdoor environments, this compact box may not meet those demands. It also relies on you remembering the code, if you frequently misplace codes, a more feature-rich locking solution might be preferable.

What to check before you buy

Ensure your intended mounting location can support a small wall box and that you’re comfortable with a 3.5 cm depth. Consider whether you need a dedicated cover for weather protection beyond the built-in guard and confirm the accessibility of the lock mechanism when mounted in your space.

Practical usage example

A real estate agent keeps a key for a property in this box near the front door, sharing the code with colleagues during viewings. The cover shields the mechanism from dust as it sits by an entrance that can accumulate dirt, helping the mechanism stay reliable over time.

What stands out in use

It’s minimal in size and appearance, yet provides a resettable 4‑digit code and a protective cover. The combination of aluminium and zinc alloy suggests durability and rust resistance for daily, light-duty use.

FAQ

• How many keys can it hold? The base description implies space for at least one key, larger capacities aren’t specified, so it’s best treated as a small, single‑key storage solution.
• Is the code easy to reset? Yes, the 4‑digit combination can be reset as needed for enhanced security.
• Is it suitable for outdoor use? The cover protects the lock from elements, but there’s no explicit weatherproof rating provided, so consider sheltered placement if exposed to rain or heavy dust.
