Combination locks are a great way to keep your valuables safe. You can secure your locker, bike, diary, etc., without the hassle of carrying a key with you. But what happens when you forget what the combination is? Do not fear! You can do a couple of things to open up your lock so you can get back to using it.
Forgot Master Lock Combination?
If your lock is not attached to anything you can look up the serial number stamped onto the back. Once you locate it you should follow the correct procedure to mail a photocopy to the master lock company to get the combination. If there is no serial number, or the lock is attached onto something this will not work, so you will need to take additional steps.
If the Lock is Being Used…
If the lock is attached to something at the time you forgot the master lock combination you have two options. You can break the lock, or figure out the combination.
How to Crack the Code
1) Turn the lock clockwise for three rotations to clear it, and leave it at zero.
2) Put pressure on the shackle part and turn the dial slowly.
3) Turn and apply pressure until you find a point where you can’t turn any further (this is the first number).
4) Continue to apply tension but start turning left until it stops again (this is the second #).
5) These two numbers are the sticking range.
6) Stop applying pressure and turn past the sticking point.
7) Reapply tension and turn to find more sticking points (there should be 12 altogether).
8) Only consider the whole numbers (this should eliminate 7).
9) Of the remaining numbers, the one that does not end in the same number as the others is the third number in the combination.
10) Divide the 3rd number by 4 and remember the remainder (this is the magic number).
11) Add 4 to the magic number and write it down, add four to that number, continue this until you have gone completely around the dial (one of these will be the first number).
12) Add 2 to the magic number and write it down, add four to that number, and continue this process until you have gone completely around the dial (one of these will be the second number).
13) Of the possible second numbers cross out the numbers plus or minus 2 from the third number.
14) Using the leftover numbers, use trial by error to try and figure out the combination.

Can you send me the dummy terms of how to do this? What I read was greek to me
Sure thing! Turning the lock clockwise means turning it to the right, the way the hands on a clock move. Counter-clockwise means turning it to the left. The shackle is the metal loop above the dial that actually locks onto an object. I hope that clears some things up for you? If you need more help, just use us to find a locksmith.
