#1. RamPro Hide-a-Spare-Key Fake Rock

RamPro Hide-a-Spare-Key Fake Rock

Key features:

  • Authentic poly-resin design
  • Windproof and weatherproof
  • Fits multiple keys
  • Versatile use possibilities

RamPro’s innovative approach to a common dilemma presents itself in the form of the Hide-a-Spare-Key Fake Rock. Aesthetically designed to mirror the natural appearance of roadside rocks, this unit seamlessly disguises its true purpose, granting homeowners peace of mind knowing their spare key is safely hidden in plain sight.


Crafted with meticulous attention to detail, it utilizes molded poly-resin to emulate the texture, size, shape, and color of genuine rocks. Weighing in at 3.52 ounces and measuring 3.4 x 2 x 1.25, this device is compact yet capacious enough to house keys up to 3 1/8-inch in length, 1 ¼-inch wide, and ¾-inch deep. Whether you’re looking to stash a house key, car key, or both, this rock provides ample space without compromising on realism.


During our testing, we nestled the rock amongst shrubs, on the garden bed, and even between other rocks. Its stone color, a mix of grey and brown, ensured it blended perfectly in all environments. An added feature that impressed us was its windproof and weatherproof qualities, ensuring the safety of stored keys even in challenging weather conditions.

However, its versatility isn’t just limited to housing spare keys. Many users might find it suitable for geocaching adventures or even discreetly hiding other small essential items.

What we liked:

  • Realistic appearance
  • Durable material
  • Ample storage capacity
  • Blends seamlessly in gardens

What we didn’t like:

  • Perhaps a bit too lightweight
  • May not fit larger key fobs

#2. Master Lock 207D Magnetic Key Holder

Master Lock 207D Magnetic Key Holder

Key features:

  • Rust-resistant plastic construction
  • Strong recessed magnet
  • Portable and lightweight
  • Compact dimensions

When it comes to safeguarding an extra set of keys, the Master Lock 207D Magnetic Key Holder stands out due to its blend of durability and functionality. Crafted from a robust plastic material, it boasts a rust-resistant property, ensuring its longevity. Sporting a compact design with dimensions of 4.69 x 2 x 1.19 inches and weighing just 2.4 ounces, it doesn’t feel cumbersome and is easy to handle. And indeed, one of the first things we noticed during testing was its size. 


Contrary to our initial expectations, the unit is slightly larger than anticipated. While this might be a drawback for those seeking a super-compact solution, it is an advantage for those with larger keys or those with fobs. The inclusion of a recessed magnet in its design proved invaluable. We were able to effortlessly attach it to various steel surfaces, and it held securely without any hitches. Opening it, on the other hand, presented a slight challenge. 

Despite the durability of its construction, the lid seemed prone to popping out of its track, especially with frequent use. That said, for individuals seeking a solution to stash a key for occasional access or emergencies, it’s an excellent choice. This notion is further supported by its hard-to-penetrate design, ensuring the stashed key remains safe. But this also presents a bit of a quandary. On the one hand, it’s durable enough that it could easily be buried in the ground.


But on the other, the lid doesn’t exactly give you the peace of mind that your key will stay safely inside the holder. Granted, it’s not designed to be buried, but given its tough construction, it would have been a nice extra. Be that as it may, it serves its intended purpose well. Caring for it is fairly straightforward – a simple wipe with a damp cloth keeps it looking new. With a limited lifetime warranty from a reputed brand like Master Lock, this key holder inspires confidence.

What we liked:

  • Holds larger keys/fobs
  • Secure magnetic attachment
  • Durable and rust-resistant
  • Limited lifetime warranty

What we didn’t like:

  • Lid may pop out
  • Larger than expected

#3. Lucky Line Realistic Sprinkler Key Hider

Key features:

  • Looks like a real sprinkler
  • Weather-resistant plastic case
  • Easy unscrew mechanism
  • Watertight storage compartment

Lucky Line, renowned for its extensive range of key accessories, brings forth the Realistic Sprinkler Key Hider – a blend of ingenuity and convenience. It’s easy to admire the thoughtfulness of its design. At initial glance, the hider seems nothing more than a typical sprinkler head. That’s precisely where its strength lies: in its unassuming presence. In terms of size, the unit measures 2 x 2 x 3.75 inches and has a weight of 1.76 ounces – compact enough to be inconspicuous yet spacious enough for its purpose. 


While testing it in different outdoor settings, from gardens to walkways, it nestled seamlessly, often disappearing among real sprinklers and shrubbery. Unscrewing the device was a breeze, revealing ample space to store not just keys but also notes or even some cash. The robust plastic case impressively withstood various weather conditions, retaining its watertight properties. 


However, its true brilliance shines in emergency situations. Imagine having an electronic lock malfunction or simply forgetting keys indoors. Such instances magnify the importance of this discreet backup. It stands as a testament to Lucky Line’s commitment to understanding customer needs and producing solutions in response.

What we liked:

  • Blends seamlessly outdoors
  • Spacious inner compartment
  • Durable and weatherproof
  • Simplistic, effective design

Iron Lock’s Wall Mount Key Lock Box serves as an effective and efficient solution for those seeking a sturdy, external key storage system. With dimensions measuring at 1.4 x 3 x 3.7 inches and weighing a mere 9.9 ounces, this device is compact yet robust, boasting a durable combination of zinc alloy and aluminum materials. This ensures that it’s resistant to various external elements such as sand, salt, and dust that could otherwise jeopardize the functionality of a stored key.


The storage compartment is surprisingly spacious, able to accommodate not just household keys but business keys and access cards. This adaptability makes it apt for diverse use cases, from property managers to businesses. One of the standout features is the unit’s customizable 4-digit combination system. This system, paired with the A/B switch, offers both security and flexibility, allowing for easy resets.

Additionally, the wall mount design ensures that the unit stays in place, and the included 4 screws and anchors mean that no additional purchases are necessary for setup. During our testing, the unit showed resilience against common security threats. It could withstand attempts at hammering, sawing, and drilling, thanks to its heavy-duty steel locking mechanism and thickened compartment.


In practice, this lock box has proven invaluable for users like remote landlords. For instance, a landlord with a rental property in a college town found it useful for providing key access to a constantly rotating tenant base without the need for physical presence. Such utility and longevity, even with frequent daily usage, accentuate its worth.

What we liked:

  • Durable against environmental elements
  • Spacious storage compartment

#5. Sungmor Cast Iron Turtle Key Hider

Sungmor Cast Iron Turtle Key Hider

Key features:

  • Antique green cast iron design
  • Freestanding mounting type
  • Portable with cute shape
  • Oil rubbed finish

The Sungmor Cast Iron Turtle Key Hider, with its antique green finish, exudes a touch of nostalgia and charm. Made entirely of cast iron, the unit boasts a robustness that ensures it’s not just an attractive decorative piece but also serves its purpose as a key holder efficiently.


During our tests, we found the unit to be substantial in weight at 1.76 pounds, a testimony to its solid build quality. This weight makes it stable, ensuring it doesn’t easily topple over when placed on various surfaces, from the front porch to the back garden.

Its design is reminiscent of something from a bygone era, with the oil-rubbed finish adding a sense of antiquity. In terms of dimensions, it comfortably sits at 4.9 x 3.9 x 2.7 inches, making it an ideal size – noticeable yet unobtrusive. Its freestanding nature means you can easily place it wherever you see fit without the need for any mounting.


Interestingly, while it’s primarily designed to be a key hider, its quaint and endearing turtle design, coupled with its finish, makes it versatile enough to be recommended for uses beyond its intended purpose, such as an earring holder. It has the ability to seamlessly blend into various décor styles, whether country, contemporary, or otherwise.


All sounds perfect, right? Unfortunately, there is a caveat worth noting. And that is its susceptibility to rust. Like many cast iron items, there’s potential for it to rust over time if exposed to moisture. And since its primary function is to serve as an outdoor key holder, this presents some concern. If you regularly maintain it or take preventive measures, such as applying a clear coat, you can combat rusting to some degree.

What we liked:

  • Robust and weighty build
  • Versatile decorative uses
  • Classic, nostalgic design
  • Adequate size for key hiding

  • Prone to rusting

Constructed with high-quality resin, the Memeyou unit guarantees durability. It can endure the outdoor elements, further evidenced by its water-resistant lining, which protects keys from the elements, particularly moisture and humidity. The push-open slider on the bottom ensures that stored keys remain secure. Plus, the spacious internal compartment means it can hold various key sizes, inclusive of bulkier car keys.

Another standout feature is its fire resistance, providing an added layer of security. During our tests, we found that its design indeed blends effortlessly into the outdoors, especially after a few tweaks. However, the bottom sliding door presented some initial challenges, making it a tad tough to open and close. Nonetheless, its practicality, especially for home use, can’t be overstated.

  • Fire-resistant feature
  • Blends seamlessly outdoors
