You could have the correct combo... but not be using the correct pattern. Here it is.
Turn dial several times to the right to clear it...stop on 0
Turn dial to left (ccw) 3 times past the first number and then stiop on that number the 4th time around.
Turn dial to right 2 times past the second number stop on that number the 5rd time around
Turn dial to left 1 time past the 3rd number and stop on the 2nd time around.
Turn dial to the right until it latches (could be the last number or the drifted number) until it stops
Twist handle and open door.

NOTE:If this fails to open it then its possible (after years of use and w/o service) that the numbers 'drift' from there original spot. You can try to find this out by applying pressure to the handle (which engages the 'fence' inside and rubs it against the wheel pack). While applying light pressure rotate the combo dial and where it locks up should be one of the numbers... check this against your 'correct combo' and see how they match. If it's off then all of them are off. You'll need to determine the 'new' combo by drawing the dial with the numbers use the fence located number (usually the first or last) and then reverse engineer the combination. You may also want to grab a book on safes/ safe-cracking to understand the mechanics if this doesn't make sense. Good luck!

Hello,
Same thing happened to me today. (Bell kevlar combo lock 12 mm) I sprayed WD4 0 on my lock (probably wasn't necessary) and let it soak in. I looked up videos online which weren't very helpful. I kept trying to open my lock and I happened to move one of the four digits and it opened. I'm not sure how the lock pins work but it seems like if you lock your bike and move the lock into ackward positions you can cause one or more of the pins to move. My combo was 2194 and I opened it with the combo of 2294. Go ahead and try your combos +/- one number at all four positions. Hope this helps.

It would appear that you made a mistake in setting your new combination on your Master Lock 5400d and did not register the combination at Masterlockvault.com. The only way to open your lock is by using the correct combination. There is no other way. Most mistakes are normally one or two digits out, so you may wish to try variations on what you thought you set.

Apart from that 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.
