Review

The absolute best outdoor key lock box is from the reputable Master Lock.

Kingsley Guard-a-Key Black Realtor's Lockbox

Review

Next on the list is the best portable key lockbox, the Kingsley Guard-A-Key Black Realtor’s Lockbox. Similar to the Master Lock model previously reviewed, the Kingsley Guard-A-Key is capable of hanging on many doorknob styles. The main distinguishing feature of this lockbox is the manner by which it opens.

The side of the lock box with the combination dials opens out away from the box, allowing you to place keys inside the unit. This differs from the Master Lock model because the lock bar must unlatch to retrieve or store keys.

What Customers Are Saying

Consumers are generally in agreement that this key lock box is practical and that its capacity as described is very accurate. Some consumers are shocked with its capacity given the unit’s slim design.

Pros/Cons

  • Four (4) digit locking mechanism allows for thousands of different combinations
  • Fits most door knobs
  • Durable build
  • Side loading makes key retrieval slightly more involved (good for preventing thieves)
  • Large capacity of up to 10 keys
  • N/A

Summary

The Kingsley Guard-A-Key is perfect for those who are looking for an easily accessible, yet not easily crackable, key lock box. With such a large capacity, this model is great for realtors, contractors, and others who deal with properties frequently.

At the third spot is one of the best lockbox for houses, the Buteny Key Lock Box. This key lockbox is very similar to the Master Lock 5400D model reviewed at number one. As with the Master Lock model, this Buteny Key Lock Box opens in the front of the unit, which means that it can be opened without taking the unit off of the door.

Further similarities include the dials for code combination and a protective shutter that protects the dials.

What Customers Are Saying

Review

The next best portable lockbox is another offering from Master Lock. The Master Lock 5424D can be seen as the upgraded cousin of the Master Lock model reviewed at number one.

The 5424D operates nearly identically, though it is constructed a bit more carefully with higher-end features. For instance, the code dials light up for help unlocking at night, etc. In addition, this unit holds on average one more key than the Master Lock 5400D.

Also, this unit has a full cover piece protecting the unit, unlike the shutter protector on the 5400D.

What Customers Are Saying

Consumers again have mixed reactions to this Master Lock 5424D model. Some call it sturdy and rugged, however, many others call it cheap and easily crackable. In addition to some having been broken into, others claim their units stop opening after a while.

  • Fits most door knobs
  • Durable build and has extra protective cover

Given the consumer response to the Master Lock products, it is not recommended that this unit be used for security purposes in high traffic areas.

Review

The next best key storage lock box on the review list is the MoFut Key Lock Box. While the design of the MoFut Key Lock Box differs aesthetically from the Master Lock and the Buteny models, it essentially functions in the same manner.

The most differentiating feature is the dials for code combinations sit on its own face piece, covered by another face piece that serves to protect the unlocking mechanism.

Review

The next best home lockbox is the SAFEGO Portable Indoor/Outdoor Lock Box Safe. This lockbox safe is the most unique lockbox reviewed thus far.

The reason behind the model’s unique design is that it is not meant entirely for keys. The SAFEGO model is essentially a normal lockbox for all types of valuables, not just keys. It’s about the size of a small women’s purse.

The unit has a three (3) digit locking mechanism as well as an access key. So this lockbox, while storing other keys, adds a key that you have to keep track of.

Consumers are generally happy with this product from SAFEGO. However, it should be noted that most consumers don’t use the lock box for keys at their homes. This unit is popularly carried around to places like the beach, the pool, etc.

Pros/Cons

  • Large storage capacity
  • Flexible steel cable allows for the key lockbox to be attached to a variety of objects
  • Durable build and waterproof

  • Not very concealable due to size

Summary

The SAFEGO Lock Box Safe is great for those looking for a portable key lock box. While this unit can be used at the home for protecting house keys, it’s more suited for those on the move with valuables to protect.

Review

At the sixth spot in the reviews is the best wall mounted key lock box on the market. The TOWOKE Key Lock Box has near identical construction to the Master Lock model aside from the lack of a shackle.

What Customers Are Saying

This model from TOWOKE has satisfied its customer base immensely. The lock box is highly durable and withstands the elements easily. And while it is a mountable lockbox, consumers claim it is fairly easy to install.

Key Safe Lock Box Outdoor Storage Box with Code Combination Password Security Lock Waterproof Wall Mount Push Button for Home Family Realtor 10-Digits

Review

This next model is one of the most weatherproof key lock boxes in review. The Newprous Key Safe Lock Box is unique form the rest of the key lock boxes in review because it does not have dial code combinations for locking and entry. Instead, the unit has ten buttons for numbers one through nine and zero.

This adds a bit of difficulty when it comes to those who may try cracking the lock box. Like the TOWOKE unit previously reviewed, this model mounts directly to a wall surface. When unlocked, the entire face comes off of the key lockbox.

What Customers Are Saying

Consumer reviews are rather mixed with some claiming the unit to work suitable while others call it cheap and easy to crack. Some consumers point to poor construction while others note the low key capacity, with some even claiming it to be smaller than described.

Pros/Cons

  • Harder to crack locking mechanism (10 digits)
  • Wall mounting key lockbox, comes with screws for mounting
  • Easy installation
  • Durable build and waterproof
  • Very low key capacity (3)
  • Unit material unknown

Summary

While it may not be the best key lock box this unit from Newprous is good for those who don’t like to carry their keys. Due to the consumer reviews you may want to think twice about using this unit particularly for security against crime, namely thievery.

Reliance Safego, Indoor/Outside Portable Security, Black

Review

Up next is another outdoor key lock box, or lock box more generally. The Reliance Portable Travel Lockbox Safe is very similar to the previously reviewed Reliance Portable Indoor/Outdoor model.

The Portable Travel Lockbox Safe is designed with a different shape, falling more in line with the key lock boxes discussed thus far. That means this model has slightly less capacity than its counterpart. Like the other Reliance model, this unit has a three-digit code dial access with an access key.

What Customers Are Saying

Consumers love this product from Reliance. Particularly, consumers note the size of the unit as being easily transportable and great for protecting valuables on the move.

Pros/Cons

  • Medium storage capacity
  • Flexible steel cable allows for the unit to be attached to a variety of objects
  • Durable build and waterproof
  • Easy to carry around or transport
  • Not solely for keys, and because of this there’s a key needed for locking/unlocking

Summary

Reliance has created another well respected key lock box for home keys and other valuables you may need to protect. This model is perfect for the adventurous types who love to stay active and explore yet need their valuables protected.

Review

The final product in review is another outdoor key storage box. The CONNYAM Key Lock Box is similar to the TOWOKE product previously reviewed.

Like the TOWOKE unit, this offering from CONNYAM mounts to a wall surface and is not meant to hang on your door. The design follows the traditional route with dials for code combinations on the face of the key lockbox that then opens out. Much like the other models in review this model has a shutter door to protect the dials from the weather.

What Customers Are Saying

Consumers love this product from CONNYAM, claiming the box is heavy duty and super easy to use. In addition to installation being relatively simple, consumers claim this unit holds up well over time and to the elements.

Pros/Cons

  • Four (4) digit locking mechanism allows for thousands of different combinations
  • Highly durable build (zinc alloy and steel very difficult to break)
  • Easy installation
  • Only holds about five (5) keys
  • Mounts do not hang on a door

Best Places to Put Your Key Lock Box

The following is a list of the best places around your property to place your security key lockbox:

The Doorknob

best lock box for house keyFor those among us who are less interested in protecting against crime and are more focused on providing accessibility for others, the doorknob is the spot for your lockbox.

For instance, an option like the Master Lock 5424D is the best key lockbox for AirBnB and other similar endeavors.

Therefore, placing the unit on the door would be the most helpful to your tenants/renters, or really whoever you are allowing into your home or property.

Walls

best portable key lock boxThe next best place for a key lockbox is the wall. As we can see from the reviews, there are plenty of mountable options on the market.

The key is mounting the unit in a place that is not necessarily out in the open or highly visible. Garden: mounting the key lockbox low on a wall hidden by the garden could be a great spot.

If you have a shed, perhaps mounting a unit to the back and out of sight is the most practical solution.

If you have ladders or are on the taller side, mounting high up on walls out of the natural site and reach could be best.

Hidden Corners/Crevices

key safe lock box reviewsThe third best option for where to place your key lockbox is any corner or crevice on your property. Any spot that will reduce visibility and attention is a viable option.

There is no reason to remain nearby the door with the lockbox. If anything, this draws attention to the lockbox and shows those passing by that there is a key on site.

Any area that is hidden or out of site will get the job done. If you have a large property, consider keeping the keys in an obscure location that no one would naturally search.

Conclusion

Which is the best lock box for house keys depends on the manner in which you plan to use it. If you need high security, consider one of the mountable units and placing it out of sight.

If you simply need a lockbox for others to enter your home with your consent, a simple door hanging unit could be for you. Regardless of your intended use for the lockbox, there are plenty of options on the market to suit your needs.

By analyzing the various features of the key lockboxes, such as material durability, locking mechanism, and size, we’ve narrowed down some of the best units available.

With the help of these reviews and some attention to your own needs, you are sure to purchase a unit that works best for you. Get a key lock box today and reduce the stress of hiding your keys!
