Hi everyone. In this video we're going to talk about how to set a three-digit master lock. So this master locks combination is shown on this side. So you'll notice that there is a little arrow right here and then the three-digit set it set to. So this one set to 621. Currently I have the latch open but what I should be able to do is to push it all the way in and it should if I twist the numbers so that it changes I shouldn't be able to pull it out anymore. So I'm going to switch it back to 621 and it should pop open. Okay? So once you know that it's set to the original lock that it was set to before you can now change it. So on these locks if you look at the top you'll notice that there is a little niche right there and then if you twist this you'll notice that there's a little extra silver part. So that needs to go inside. So you're going to press that down and you're going to keep it pressed while you reset the lock. So now you can change the lock numbers. So I'm going to change it to 732. Once I have that done I can let go of the top and pull it out and it should do the same thing now. So I should be able to push it in. Change one of the numbers. So I 832 now and it should not pop out anymore until I move it back to the original lock combo that I switched it to and then it should come out. And that's how you change a three digit master lock combo.
