Master Lock Set-Your-Own Combination Locks Review



Right 23, Left 12, Right 7. Ah, childhood memories of locker combinations, skipping class and bullies. Those were the days my friend… Not! But maybe we can make school just a little bit more fun for kids these days with the new Set-Your-Own combination locks from Master Lock.


Master Lock has introduced two new locks. The 1590D, with a familiar rotary dial, but with letters in addition to the numbers. And the new 1500iD Speed Dial lock with a spring loaded joystick. Both locks can be customized with your own combination.


Both locks are made with metal bodies and hardened steel shackles. The Speed Dial lock has a 2″ (51mm) wide body, while the rotary lock is 1-15/16″ (49mm) wide. Both locks are also available in several colors including Red, Blue and Black.

The Speed Dial lock is very unique because it has a 4 way directional combination input button instead of a rotary dial with numbers. The dial is spring loaded and is easy to use. Just use your thumb to slide it in the desired direction and when you let go, it slides back to the center. This type of lock would be considerably easier for a visually impaired person to use, since only touch is required to open it.


A reset switch on the back allows you to set your own combination, which can be any number of movements (Up, Down, Left, Right). Of course, to be able to actually change the combination, you have to first KNOW the current combination. 😉 So there’s no worries that someone will flip the switch on the back of your lock in order to open it without your authorization.


A sheet of stickers is included with the Speed Dial lock if it’s easier to remember the combination visually, instead of by direction.


The rotary lock works as you would expect, but it now has letters in addition to the numbers. The dial has a nice feel when you rotate it. There’s a tactile  click for each number / letter.

A combination is made up of three digits or letters or a mixture of letters / numbers. You can even repeat letters and numbers. A special key is required to customize the combination.


You have to open the lock and then stick the key into the shackle opening and turn it. Then you can set your own combination. Easy, but don’t lose the key if you want to change it again in the future.

Both the Speed Dial and the rotary lock feature anti-shim locking technology, which is supposed to make them more secure than traditional combination locks.

I tried both locks on some lockers at my day job and as you can see from the images above, they worked as expected. The only thing I noticed is that the Speed Dial lock is a bit harder to get the shackle in and out of the lock handle. I think it’s due to the shape of the lock body and the fact that the shackle loop is shorter. It’s not THAT big of a deal, but I did notice that I had to wrestle with it just a little bit.

Master Lock is the world’s largest manufacturer of padlocks, and these new locks are affordable, sturdy and easy to use. I really like the fact that I can set my own personal combination instead of remembering one that has no meaning for me.

    Bought today the 1500iD Master Lock. Worked fine when on default combination. I reset the combination to my own one, tried to open it and didn’t work! Now it’s useless. 10 bucks thrown away. Good idea, poor implementation. They should recall.

    An earlier post fixed my issue…after resetting the combination, the lock would not open. I did recommendation #2 and it worked… I was able to reset the lock.

    Read all details about this lock at (at the bottom of the page)

    If you can’t open it after re-programming, try this:
    1) just push in the shackle and pull it up, you might have accidentally pushed in the shackle (reset the lock) during reprogramming.
    2) push the shackle in, then dial the old and then the new combination; you might have forgotten to reset the lock during reprogramming
    3) push the shackle in, then dial the new combination, but let the knob snap back instead of guiding it back. Or, if you usually let it snap back, guide it back this time. Letting the knob snap back might give a different result than guiding it back: Letting it snap back might effectively move the knob halfway into the other direction as well.

    Masterlock. I am tempted to buy these locks, but you need better instructions. I read the info on the packaging, and i dont get it. So I am not going to purchase. Potential costumers shouldn’t have to google or search for Youtube instructions.

    reset my new lock following the instructions enclosed and now cannot open the lock …What the heck…a costly lock and now its useless

    I had the same experience with the 1500id model. I tried two of them, and neither would open after the combination was reset by me. Finally I bought a third one and simply stayed with the preset factory combination. I like the concept of quickly opening the lock. Now the problem is that after a few months of use the preset factory combination no longer works, so I had to cut the lock off. I have wasted a lot of time, money, and aggravation on these locks. Good concept, but not ready for prime time!!
