        If the lock is truly "unlocked", just look at the numbers that the lock is currently set to. But is the lock really "unlocked", or just open? It can be open, yet still in a locked setting. You can find out by closing the lock.

        By|Jul 22, 2022

          The factory set code is 0000. Use the instructions to set a new code. If this lock has been used and you don’t know the code, you will have to find a locksmith.

              By|Jan 24, 2021

              Yes they do. It’s easy to set and reset your combination as needed with the supplied key

              You must keep a record of input code for future information. You are provided with a reset key to use in order to change the lock combination. Again be sure to keep a record of the changed input combination.

              By|Jan 24, 2021

              It cannot be reset without unlocking the lock with the combination. This prevents anyone else from opening the lock. When the lock is open there is a key to insert and change the combination.

              By|Sep 10, 2019

              If you don’t have your key pin that came with your lock you might be able to use a pin to stratal the pins underneath the lock. Once you unlock it first it would take a long time to turn the dial under the lock but it would take you a long time , if your able to unlock then reset it simple and write it on a piece of paper and Hide it where you normally would not forget where the new code is . IF THIS METHOD DOES NOT WORK FOR YOU AND IS TAKING TOO LONG BUY ANOTHER LOCK AND IT WOULD BE WORTH IT. This Master lock is a good price and sturdy .

              Yes you can.

              By|May 4, 2023

              Yes, the key only clears the current code once you have entered it, and locks in whatever New code you set. the key is NOT unique to EACH lock.......

              By|May 4, 2023

              yes, this works well when you have different employees and they can all have different codes. Just make sure you write all of the codes down for your reference.

                          Looks like a small key for a very small lock.

                            Small PLASTIC "key" that fits into lower side of lock. I would imagine they are ALL the same, the security is that you have to know the combination to open the lock to "reset" the combination.

                            By|May 4, 2023

                            It looks like a small skeleton key. you have to dial the current combination, insert and turn the key 90*, dial the new combo, then remove the key.

                                [This review was collected as part of a promotion.] Recently got this new Master Lock Combination lock and I had forgotten how much I like MASTER LOCKS. It seems like finding keys is harder than remembering a combination so I always can open it at any time. It works both indoors and out and is sturdy, well built and dependable. Don’t need batteries, internet or a cellphone to use it. Like that it also comes with a small key just in case I forget the combination I can still open it. I’m going to love this lock for a long time!!! Highly recommend!!

                                  [This review was collected as part of a promotion.] This is an easy process to set up. The key is inserted into the lock after you open it. When you turn the key sideways, it locks into place, allowing you to set the combination of your choice. Once satisfied, remove the key and you're done! Simple and easy. It is critical to keep track of the key so that you can reset it in the future. My daughter needs one for her gym locker, so this is a convenient way to protect her items from theft. As far as durability goes, it's above and beyond perfect for the purpose we are using it for. She is Eight, and can unlock it easily after working with her. We love it!

                                    This is a great lock if you have many locations that you need to have the same "key". It will save you from having to carry from site-to-site a large key ring of different keys for different locks. It also helps with security, as in when an employee leaves, you can then change the combo. I do, however, recommend frequent maintenance and cleaning in high dust and dirt environments as this lock can become stuck and unable to be opened. Also, if using in freezing environments, I also recommend carrying a hand-held torch (not a lighter, a torch). Once snow is on it, as soon as the sun hits it melts into the mechanism and then freezes overnight, again, making it impossible to open without a high-heat source. All-in-all I have been pleased with the performance of this lock over the past 8 years of using them, and would highly recommend it to anyone in need of this type of lock.

                                    This combination lock works well for us. We can change the number quickly and easily to provide the security as needed without the concern of needing keys. Works well on most hasps for temporary doors and medium size chains for locking jobsite fences and even locking small equipment to a secure location. Good overall longevity and versitilty.

                                    Works Ok Until it Doesn't
                                    I keep buying this brand because it's the only one at Home Depot that fits my garage and that I can change the combo. But after about a year, the lock stops closing so I have to replace it. I called the company and they said use 3 in 1 oil. But they wouldn't replace it.
