Flava - I work with a lot of I-Cores at work (probably since I'm the only one there that knows jack about locks

) Here's some hints:
1) 180 Degrees - baaad - the problem is that you may have dropped some drivers into the bottom of the lock. To construct the lock's bible (top pin chamber) some locks have holes in the bottom of the lock. Try turning the lock upside down and gently rapping it on a hard surface while (gently!) turning the key.
2) Control - it IS a standard, if you are picking to the control shear it always turns clockwise. Barely 15 degrees, so if you feel the plug turn a bit, try gently pulling out the IC - you might have picked it and not known! It is rare for these to have spools or mushrooms so if the cylinder turns a bit, you might have hit the control shear.
Enjoy! I've always liked IC's, pure lockpicking at its best
