        No, you change it based on your need to do so.

          After opening the box, you must push the reset button down to close it. If you entered the combo wrong, you must push down on the reset button before you can enter the code again.

              How do I reset the combination on this lock?
              ByApr 11, 2025
              1 Answer | 
              Answer This Question

              To set a new combination on a Master Lock 5422D push-button lock box, open the lock box, locate the yellow buttons, and use the recode tool (or a small flathead screwdriver) to push and turn the buttons you want to use to the "SET ON" position. Ensure the other buttons are in the "SET OFF" position. Once set, the lock box is ready for your new combination.

                      Although it has a picture of a key fob. It is not deep enough to hold a key fob.

                        Needed an option for pool guy/exterminator/family/friends access to my yard and the outdoor smart lock I had on my back gate didn’t last a year. When I saw this was from Masterlock, I knew it was good quality. So far so good and easy to set up. Recommend!!!

                        Beware Ordering
                        I have ordered many, many products from Home Depot. While many of them arrive in expected condition, many also arrive in quite clearly repackaged or plain half-torn open packaging! Although the products themselves seem at first glance to be in ok condition, Home Depot ought to do a lot better. These items are being sold at full price, yet they look like they came from a bargain bin. They should not include items in this state when fulfilling delivery orders. They certainly wouldn’t do this if you bought these items in person. I expect a little more honor in a shipped order. There is then the nuissance of having to perform extra inspection, submit reviews, take photos, get item exchanged/refunded etc. As somone who has worked in shipping myself, I am dissapointed.

                          Heavy duty key lockbox
                          I was looking for a key lockbox that would accommodate at least 3 keys, was wall mountable and had a mechanical keypad. This lockbox meets all those conditions plus it is easy to program, or re-program, and higher quality compared to cheaper lockboxes. I also like the fact it has an additional cover that protects the keypad from the elements. I would highly recommend

                          DON'T WASTE YOUR MONEY!
                          I bought this box thinking it would be a good solution to locking myself out. Turns out it is a really easy solution for thieves to access the keys to get into your property and steal from you. Took them about 5 seconds to break it. Not worth the crap metal it's made out of.
