ok, so here's the deal.
I have a 5-pin tumbler brand:defiant, and the pin setup is like this:
key way -> pin -> pin -> pin -> pin -> spool pin
so the back-most pin is a spool pin, and all the rest are just normal.
Now, I can pick it when it has 5 regular pins, or when it has 3 regulars and a spool, but for some reason when there is 4 pins and a spool, like shown in my diagram, I can't get anywhere.
Every time I am finished picking and give up to try again later, i only ever hear 2 clicks while slowly moving the tension wrench back.
Anyone have any idea what I'm doing wrong..? Is this a common problem?
