Ratings & Reviews for Master Lock Door Knob Combination Push Button Lock Box

Great lock

Got 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!

Super 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

Sturdy 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

After 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

This 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

So 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

I 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

Sturdy 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.

This 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

This 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!

This 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.

Great box

Great waterproof lock box. Has a nice amount of storage. Buttons are fairly easy to push. I will use it for my kids when they come home from school to get the key for the door

Nice security Option

The lock box was easy to set up and mount. The instructions were clear. It seems secure and I look forward to the convenience it gives guests to this house.

Stuck, cannot open.

Does not work

Disappointed in Product.

Product is not user friendly and does not seem to work properly. Directions for use are confusing and not clear. Was looking forward to reviewing this product but very disappointed in all aspects.

Cheap piece of trash

Do not depend on this so called lock box for your safety. After a few months of light use, it stopped being able to lock. All it takes to open the box is to press the clear button. Waste of money.

Much needed

Easy to change the code

After purchase, check functionality before leaving

Buttons seem cheaply made, plastic cover is hard for some people to open, and the first two (2) units I picked up were defective (didn't lock what-so-ever). I would definitely check the unit after purchasing and leaving the store. Lowes was great with the return and their tech was stumped on why the units wouldn't lock. A quick swap was done with Lowes. I only went with the same units because I, regretfully, installed one unit on the wall before I checked them out for functionality.
