How do I unlock a
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.
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.
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.

I forgotten my skybag number lock how to open the lock .
You can try to determine the combination by pulling on the shackle and moving the combination wheels until one of them clicks (or feels) different from the other numbers. Do the same for the other two number wheels. Lots of trial and error, but it has worked before.

How do you crack a master lock 1534d?
I just unlocked a 1534 4-digit lock I couldn't open for 2 years. I found the info online. Use a flat blade to spread the wheels apart slightly and look for the red mark on each wheel. There were only three metal tabs on each wheel on mine so if this is the same on yours and you can't find the tab with the red mark, worst case senario would be to record each number shown at the mark when one of the tabs is lined up. It will take 3^x turns max to find the combination without locating the red marks. For 4 wheels, that is 3x3x3x3 or 81 possible combinations. For 5 wheels, it would be 3x3x3x3x3 or 243 possible combinations.
If you can find all but one red mark, line them up with the mark on the lock and go through all digits on the one you couldn't find. Shouldn't take too long. I tried to unlock mine by brute force (every possible combination of 10000 choices) and ran out of steam less than half-way through. That was with only 4 wheels and 10 digits each.
A serial number lookup
No, no, no, no. That won't work. Otherwise, anyone could get the serial number, get your combination, and open your lock.

This seems to be the best site for figuring out the lost combination. Follow all the directions and you will eventually get the combination.
