I have an old Master Lock 3 digit keychain lock I can't unlock and I do know the combination


Hello, Amy -

If you have not already done so, I suggest you contact the Masterlock company regarding how to obtain the combination for your lock.

This is the link to the Masterlock homepage:
https://www.masterlock.com/

On the homepage, you should see a link to Service & Support near the top of the page. Click or tap on that link.

On the Service & Support page, you should see a link to Lost Combinations. Click or tap on that link.

On the Lost Combinations FAQs page,if your lock is an "old style" dial combination lock, first open the first question: Q: I've forgotten the combination to my standard dial combination lock. Follow the on-screen directions.

Look through the list of other FAQs and open any which are relevant to you and read the information provided.

Best wishes.

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.

    How can i reset my master lock


    The only way to open your lock is by using the correct combination. There is no other way.

    You can either try every possible combination or you will need to contact the manufacturer. But they cannot assist you if the lock does not have a serial number (they recently stopped applying serial numbers for greater security) and they will not assist if the lock is already secured to anything. There are a number of other hurdles as well, click here for details. Given that they state that you will have to wait four to six weeks for an answer, it's going to be far quicker to just try every possible combination
