SOURCE: I previously set my combination

Try rotating the numbers on the combination dial three times to clear any previous entry (stop on the zero's if this applies) and enter your combination one more time to see if this works and gets it open.

The default is 000; to set it, hold the lock open, move the dials to your numbers, and close/open three times. This will set the combination to your numbers.

How do I can unlock dial lock

The master dial lock is the world's best selling combination padlock.The lock uses three digit combination of 40 numbers.allowing for 15,00 possible variations
.Follow these step to unlock dial lock. 25284217-gdc3ufgmlwaqnv2deqjxyac2-5-0.jpg With the Combination Step 1 Turn the lock until the numbers read right-side-up. Roll the left-most dial until the first number of your combination lines up with the scored hash mark just to the left of the dial.
With the Combination Step 2 Roll the middle dial until the appropriate number lines up with the number to its left. Do the same for the right-most number. Your three-digit combination should now show, left to right, lined up with the scored hash marks.
With the Combination Step 3 Pull the body of the lock away from the U-shaped metal ring without turning any of the dials. The lock will click open to expose a hook. The hook spins 360 degrees so that it can be placed onto, and taken off, luggage.
Forgotten Combination Step 1 Pull the body of the lock and the U-shaped ring away from each other to put pressure on the mechanism inside the lock. Pull the body of the lock away from its attachment, or, if the lock is not attached, apply pressure on the U-shaped ring away from the body of the lock with your fingers. Keep holding a firm, steady pressure.
Forgotten Combination Step 2 Roll the dial closest to the U-shaped ring slowly, while keeping steady pressure on the mechanism. The dial will get difficult to roll over three consecutive numbers, and one of those numbers will click. You should feel and hear this small click, and that is the first number to your combination.
Forgotten Combination Step 3 Repeat Step 2 with the middle dial, and then the farthest dial. Leave the dial set when you find the click, moving onto the next dial. The combination will reveal itself, letting you pull the U-ring away from the body of the lock.
Resetting Your Combination Step 1 Hold the body of the lock so that the numbers face away from you. Set the combination and release the U-shaped ring.
Resetting Your Combination Step 2 Turn the hook of the U-shaped ring counterclockwise 90 degrees until the notch on the stem of the hook and the hole on the body of the lock line up. Push the stem of the hook down into the body of the lock as far as it will go.
Resetting Your Combination Step 3 Turn the hook another 90 degrees counterclockwise while it is depressed into the body of the lock.
Resetting Your Combination Step 4 Roll the dials until you have your new combination.
Resetting Your Combination Step 5 Turn the hook 90 degrees clockwise and raise the stem out of the body of the lock. Turn it another 90 degrees clockwise and push it back into the locked position. The lock now uses your new combination.

    I got the master lock speed dial combination lock but forgot my combination and it won't open. can somebody please tell me if i can reset the password?

    1. Contact Masterlock.com and fill out the form, get it notarized and send it in for the combination to unlock it based on the S/N which is on the lock.(http://www.masterlock.com/faq/LostCombinations/). Good luck on this since Masterlock will end up finding something that will prevent them from giving you the combination. Its quite frustrating and NOT worth the trouble.

    2. Go to home depot. Buy a 24in bolt cutter ($22) cut the stem of the lock. and replace with a new lock that you can buy from home depot for $ 29.00. If you have a key that is inside the lock box that you really need, You will now need to drill out the combinations piece by piece and the door will pop open or send the lock back to Masterlock. They will retrieve the key for you and send it back.

    My Brass Master Lock Combination Lock is refusing to unlock. A couple of the combo numbers seem to be "sunk in" a bit. I tried WD40 but still will not unlock and I need to open my gate. This lock...

    You need to make sure you are putting the righ combination. Try to put it the opposite way also for example

    3645 or 5436

    How many numbers are in the combination?...if it is a 3 number system it should be easy.
