What Customers Are Saying
Customers overwhelmingly praise this lock box for its ease of setup, reliability, and weather-resistant durability. Most appreciate the intuitive programming process and ability to use any digit combination without specific sequence requirements. Many find it sturdy and practical for storing spare keys across multiple properties. However, some note the lock accepts any permutation of entered digits, reducing security against determined intruders. A few report the closing mechanism requires re-entering codes, which feels cumbersome. Despite minor limitations, most customers consider it a worthwhile, convenient solution for everyday key storage needs.

Would RecommendThere are so many uses for this master lock, lock box I love that we can put a spare house key and only give out the lock box code to who we want to have access to our home when we aren’t home. And have that piece of mind that not everyone has full access to our home. Master lock is the best lock manufacturer out there and knowing I have that type of lock to secure my house keys is definitely something that keeps my mind at ease. It is extremely well built I would definitely recommend it to ever...
Great lock
Would RecommendGot this lock for our back door so the kids would be able to get into the house without worrying about them have and losing a key. It is easy to get or reset the code, and very easy to use. My daughter thinks it great and feels better that it is there.
Easy to use and secure!
Would RecommendSuper convenient and easy to use. I was surprised at how easy it was to set a new combination. This will definitely come in handy when leaving a key for contractors as I tackle my next remodel project.
Super convenient
Would RecommendSturdy and waterproof ,this product comes in handy as I am a contractor ,I no longer have to make multiple copies of keys,also great for personal residence if a family member needs access.
Rugged secure outdoor lock
Would RecommendAfter locking myself out of the house, I needed something to lock a key in outside. This waterproof key holder is the perfect idea. It is super simple to set the code from inside the lock with the turn of a few screws with the supplied tool or screwdriver. The loop at the top is very large and is made to go around door handles. I wrapped it around an installed conduit on the side of my house. There is plenty of room for multiple keys inside the box. Operating instructions are inside the pl...
Not bad
Would RecommendThis works well, it appears to be heavy duty and seems like it will last a while. It is easy to program with any code you want. The drawback is it's a single code...you can't have a different code for different people. Also, the order of the numbers does not matter. If your code is 1234, you can enter any combination of those numbers in any order and the lock will open. This isn't the end of the world, but it does reduce security a little bit
Easy to use
Would RecommendSo I had an issue with my kids forgetting or misplacing their house keys and needed a product that was safe and easy to use to secure a spare Key. This lock is exactly what I was looking for. It was easy to program and enough room to fit multiple keys. My kids Had no issue unlocking and re-locking the device. I highly recommend it.
Quick Access to keys
Would RecommendI really like this lock box. The box has an easy-to-open cover and an easy-to-use keypad. Following the instructions to place the box onto a door knob and to program a code was easy. For now, I only placed two keys inside. This hangs on our barn door and gives us quick access to building and house keys as needed. It gives an added incentive to keep everything locked up when not in use. One thing that I am OK with, but would like to see changed is that once it is open, it tends to relock. This ...
Master Lock 5422D
Would RecommendSturdy and weather-resistant key lock box that's ideal for sharing access. The rubber cover effectively protects the dials from the elements. The combination reset process confusing, with unclear instructions leading to accidental lockouts. Overall, it’s a dependable option with minor usability concerns.
Good basic extra key storage lock box.
Would RecommendThis box is much like what you see realtors use when a house is being shown for sale. Programming it was fairly straight forward with the provided tool. Unlocking is a simple push of the combination and then push down on the button to open the box. To get the whole lock off of the door knob, there is a tiny little lever inside to release the U-shaped bolt. Closing the lock is annoying because you have to enter the code again and hold down the button as you close the door. A key with a key ...
Well thought out lock box
Would RecommendThis lock works great! I love that you can keep changing the code by turning the inside screws with the tool supplied inside of the lock. It has worked seamlessly for me for locking houses I'm working on, giving a code to a sub contractor than changing the code when they are done. Heavier than I thought and well built!
Solid lock!
Would RecommendThis lock comes with easy to understand instructions. It is heavy weight and built to last. The cover protects it nicely from the elements. Easy to reset code if needed. You won’t be disappointed.
