MASTER LOCK Extra Large Key Safe Wall Mounted

What it is and what it solves

The MASTER LOCK Extra Large Key Safe is a wall-mounted lock box designed for indoor and outdoor use. Its large internal cavity is able to hold multiple keys and access cards, making it a practical solution for households, small offices, or workplaces with shared access needs. The unit is built to be mounted on a wall or fixed surface, offering a straightforward way to grant access without needing a physical key.

How it works

Access is controlled via a resettable 4-digit combination. You can set and change your code to suit your needs, giving thousands of possible combinations for better security and flexibility. This type of key safe is intended for situations where you want to avoid distributing physical keys, yet still maintain quick and reliable access for trusted individuals.

What stands out on paper

Durability matters here. The metal body and shutter door are designed to protect the combination dials from the elements, which is useful for outdoor installations. The product is sized at 105mm wide for the lock body, with internal dimensions of 11.7 cm H x 7.9 cm W x 4.2 cm D, offering a generous interior compared to smaller boxes.

Practical use cases

It works well for homes needing to share entry codes with multiple family members or trusted cleaners, small offices with temporary staff, or vehicles that require controlled access to spare keys. The mounting hardware is included, so you can install it on a wall or other fixed surface without extra purchases.

What to know before buying

If you prioritise quick access and a straightforward code-based system, this large key safe is appealing. However, consider that a 4-digit code provides a finite number of combinations, which may be less granular than higher-security options. Also, the box is described as weather-protected for the dials, but its long-term performance outdoors will still depend on exposure and mounting location.

Pros and cons at a glance

• Pros: Large internal cavity for multiple keys, resettable 4-digit combination, metal body with weather-facing shutter, includes installation hardware, suitable for indoor or outdoor use.
• Cons: 4-digit code limits the maximum number of unique combinations compared with higher-digit options, and physical security is contingent on proper mounting and environmental exposure.

Who it’s for

This key safe suits households needing simple, shared access, small teams in a office setting, or users who want an uncomplicated way to store spare keys for vehicles or other fixed assets. It’s particularly practical if you want a low-maintenance, wall-mounted solution that doesn’t rely on electronic access systems.

Who might want to skip it

If you need advanced digital security, higher code complexity, or smart access integration, this model might fall short. Also, if you anticipate very heavy outdoor use or tamper-prone environments, you may want to evaluate sturdier or more secure options.

Buying decision: when it makes sense

Choose this unit when you want a budget-friendly, easy-to-install key storage option with a generous interior that covers multiple keys. It’s a sensible pick if you value the ability to reset codes and you plan to install it in a sheltered outdoor spot or inside a pantry/utility area.

Buying decision: when to pass

If you require frequent access changes, high security against tampering, or a higher degree of weather resistance, consider alternatives with more sophisticated or proven security features.

What to check before you buy

• Confirm the mounting surface availability and ensure you have the included hardware for a secure wall installation.
• Check the interior dimensions to ensure it fits the exact keys and cards you intend to store.
• Consider the typical weather in your area and whether additional protection (e.g., a sheltered location) is necessary for outdoor use.
• Think about how many people will access the box regularly and whether a 4-digit code provides sufficient combination variety for your needs.

Everyday example

Imagine a busy family home where one parent and a trusted neighbour need access during school holidays. The large cavity easily holds spare car keys and a couple of house keys, while the 4-digit code keeps the process simple. It’s not flashy, but it does the job without needing extra devices or smart home wiring.

FAQ

• How many keys can the interior hold? The internal dimensions suggest space for several keys or cards, but exact quantity depends on key sizes and arrangement.
• Is it suitable for outdoor installation? Yes, it’s designed for indoor and outdoor use with a shutter door to protect the dials from weather.
• Do I need a separate app or power source? No, it’s a mechanical lock with a resettable 4-digit combination, no electronics required.

Is it worth it?

Worth considering if you want a straightforward, durable wall-mounted key storage solution with a large interior and low ongoing maintenance. It may not be the best option if you need extremely high security, frequent code changes, or smart access features. A practical, value-for-money choice for everyday scenarios where simple access control suffices.
