Description

Managing spare keys doesn’t have to mean hiding them under a mat or coordinating hand offs every time access is needed. The Master Lock 5400EC Key Lock Box offers a secure, dependable way to store and share house keys while keeping control firmly in your hands. Designed with a solid metal body and a protective shutter door, this portable lock box helps shield internal combination dials from rain, dust, and everyday outdoor exposure. The vinyl coated shackle allows the lock box to hang securely over most standard door knobs and handles without scratching surfaces, making it a practical option for both temporary and recurring use. With space to hold up to five standard house keys, this key lock box supports a wide range of real world scenarios. Homeowners can grant access to family members, dog walkers, or service professionals without duplicating keys. Short term rental hosts can simplify guest check ins and reduce lost key headaches. Real estate professionals can use it to coordinate showings efficiently. It also serves as a valuable solution for emergency access planning, especially for seniors or caregivers who need reliable entry when timing matters. The resettable four digit combination gives you flexibility as needs change. Update the code whenever access permissions change, without replacing the lock or managing physical keys. This makes the lock box especially useful in shared or transitional environments where control and accountability matter. Compact on the outside yet thoughtfully designed inside, the Master Lock 5400EC balances security, convenience, and durability. Whether mounted temporarily during a project or used daily as part of a home access routine, it delivers peace of mind through simple, proven design from a brand known for dependable security solutions.

Amazing!

As a realtor, I've used just about every lockbox, this is the easiest to use by far. And they feel high quality. Would absolutely recommend!

Honestly, Here’s What I Thought
Style: Standard Shackle Size: 1 Pack Color: Black
This Master Lock key lock box is a solid choice for securing spare keys. It's easy to set up, holds multiple keys, and the combination lock adds peace of mind. Great for realtors or anyone needing secure access.

Easy to set up!
Style: Standard Shackle Size: 1 Pack Color: Black
Good and sturdy lockbox! I use this when I need to let workers into properties and don't want a bunch of keys floating around. This box is easy to set up, hide, and change the code when needed.

Good Sturdy Lock, but overall design has few faults
Style: Standard Shackle Size: 1 Pack Color: Black
It works well and is all it claims to be. It's easy to prepare and install. Simple to change the combination and the protective cover over the tumblers works nicely. The lock is very strong, sturdy and of good construction. It is surprisingly hefty and the little number dials move quite easily, even with bigger fingers. It looks like a real lock-- not like many of them that just look cheap and easy to break. The few issues I have are sadly across many different brands and seem to be issues with this style of lock, not just this particular one. My issues are that ONE, you must turn the number wheels after closing it or it remains in the open position, even though it looks locked. I often find myself forgetting to scramble the wheels thereby failing to secure the lock and essentially leaving it open, even though it truly looks like it is secured. TWO-- once the front is opened, someone could easily remove the entire lock from your door knob, as the latch that locks the handle down is easily visible and quite simple to disengage, allowing the entire lock to be removed when hung on a door knob. THREE--once lock is open, someone with minimal experience with these styles of locks, could easily change your lock code without your knowledge.-- Then you would be "locked out" of your own lock box! FINALLY -- I wish it had a chain firmly attached inside or had some way for you to attach a chain (or similar) to something other than the handle that goes over the knob (too easy to remove it then). The reason is so that I wanted to attach a chain long enough so that one could use the key to unlock the door, but could not easily remove the key from the box (to steal or make a copy, etc). We have different people coming and going, helping my elderly parents (which is why we needed something) and while you can change the combo quite easily, an unscrupulous person could very easily completely remove the key and or lock, thereby entirely defeating the security and reason for dong this. Currently you can only attach something to the hanging mechanism inside the box and once the lock box is open the chain, attached key, or ENTIRE lock can be easily and simply removed or altered. Other than these issues (common to many similar products or brands sadly), I really like the lock and would probably buy one again as these issues seem to be present in many of similar styles and brands of this kind of product line. This particular one is one of the easiest to use and sturdiest I have found despite its faults. I would probably buy again and would really like to figure out how to wall mount it! ... show more
