After closing the lock, I went to test it. The rightmost two cylinders were hard to turn, but some wiggling got them loose, so I thought nothing of it. Turned them back to 1234... nothing! It seems something got messed up in the setting process.
OK I thought, maybe I didn't disengage the setting mechanism fully, so it got half-set. Tried a bunch of small-edit-distance combos... 0034, 1233, 2235, etc. Nothing worked. So short of going through the hassle of calling the factory, yadda yadda, I was left with one choice:
Pick my own lock.
Which I really didn't want to do. Because if I, totally unskilled in locksmithing (except on weekends when I'm a 7th level gnomish rogue), were able to pick my brandy-new Kryptolok Combo, I wouldn't really feel like using it after. But if I didn't, well, I wouldn't be able to use my lock anyhow.
Being ever the tinkerer, I chose to try picking it. I tried the obvious method of starting with the left- or right-most cylinder and turning it until the lock button moved a bit, but this didn't get me anywhere. Some Googling turned up a random comment by some guy named Strider (10th level human ranger?) mentioning the "push in method". These three words were enough for me to go on.
I closed my eyes, and starting turning the rightmost cylinder notch by notch, pushing in at each stop. Most stops were pretty firm, though some were squishier than others. I stopped on the one that felt the most squishy. (Pretty subjective, eh?) OK, onto the next cylinder. These were harder to tell apart, so I picked one that felt pretty squishy... I'm not gonna get this on the first try anyway, so I'll go with it. Two cylinders left.
Hunh, this one's pretty hard to turn past a certain point. Guess I'll leave it there.
And this next one won't even turn at all... CLICK!
I opened my eyes. 0569... how the heck did that combination get set? And how did I get it on the first try?
I reset the combo to 1234, for real this time. Checked it... yup, it works. And if I ever forget it, well...
I can always pick it.
