The rectangular shape, measuring 7.19 x 5.25 x 2.22 inches, provides a compact footprint that can be discreetly mounted on a variety of surfaces, from residential doors to commercial entryways.

Designed with a push‑button controller, the lock box allows users to set a personalized alphanumeric combination, offering flexibility for multiple users or changing access codes as needed.

Inside, the box offers a 3.5‑inch high, 2.25‑inch wide, and 1‑inch deep compartment, delivering enough space to securely hold up to five standard house keys while keeping them organized and readily accessible.

Installation is straightforward thanks to pre‑drilled mounting holes and included hardware, allowing the unit to be affixed to walls, door frames, or other sturdy structures.

Whether placed on a front door, garage entry, or a gated community gate, the product’s versatile design ensures it meets a wide range of security needs.

Beyond its core functionality, the lock box incorporates a weather‑proof cover that shields the push‑button interface from rain, snow, and dust. This protective element extends the lifespan of the combination mechanism and reduces the likelihood of accidental button activation caused by environmental factors. The combination of high‑grade aluminum, a sealed button cover, and a secure mounting system makes this lock box a reliable choice for both residential and commercial applications.

Master Lock’s reputation for quality is reflected in the meticulous engineering of this model. The product undergoes rigorous testing for impact resistance, temperature extremes, and long‑term durability, ensuring that it performs consistently under demanding conditions.

Usage

This lock box is ideal for homeowners who need a secure, accessible location for spare keys, especially in situations where multiple family members or trusted guests require entry. By mounting the box near the main entrance, residents can avoid the inconvenience of hidden spare keys while maintaining control over who can retrieve them. The push‑button combination lock eliminates the need for physical keys, reducing the risk of lock picking or key duplication.

For property managers, landlords, and vacation rental owners, the lock box offers a professional solution for managing guest access. The ability to change the combination between stays provides an extra layer of security, ensuring that each new guest receives a unique code that becomes invalid after checkout. This feature simplifies the turnover process and eliminates the need for on‑site staff to hand over physical keys.

Outdoor installations benefit from the lock box’s weather‑proof design, making it suitable for use on patios, pool houses, sheds, and gate posts. The aluminum construction resists rust and corrosion, while the sealed button cover protects against moisture infiltration. Whether placed in a suburban driveway, a rural farmhouse, or an urban apartment complex, the lock box maintains its functionality and appearance over time.

In commercial settings such as office buildings, storage facilities, or service centers, the lock box can serve as a secure repository for master keys, maintenance keys, or emergency access tools. The push‑button combination allows authorized personnel to retrieve keys quickly without compromising security, and the robust mounting options ensure the unit remains firmly attached even in high‑traffic areas.
