Look at your key, the bites that are set high on the master #3, those pins require more careful attention setting. But the #3 can be raked verry easily. As always the tension is the most important thing.
Master #3's are really pathetic. Some can be easily picked even using your pick upside down and just wiggling it while applying the correct tension, which is not too hard to find.
You don't even need a pick to open the #3!
Just 2 tension wrenches! One for tension, one for wiggling around
My guess is your trying to hard, relaxe.
