So, I've become fairly proficient with picking security pins, but have a question.
I have a Kwikset padlock that Ace stamps their name on. I've come across this scenario with several other locks as well, but will use this one as an example. It's a 5 pin lock (4-hybrid spools/ 1-standard). Not relevant, but want to mention: because the serrations on these spools are so shallow, they give you no more problems than a regular spool would. Anyway, I'll try'n explain exactly what goes on in this lock.
Pin 2 is the standard driver. Pin 5 binds and is set first (though it's a spool it only takes one "click" because of it's starting height). Pin 2 (standard driver) then binds. Once pin 2 is pushed up, I'm left with a false set with pins 1,3,4 remaining.
Here's where my question comes in. There seems to be no big differences between these 3 remaining pins. They all bind, and they all give counter-rotation. Even with various amounts of tension (superlight, med.,hard) I'm unable to detect any subtle differences that would give me a clue as to which one should "technically" be set next.
With 3 pins left to set, there's only 6 possible orders in which to set them. I found that 2 out of the 6 orders will work (431 and 341) without any other falling back down. So:
1. I know my sense of feel has a long way to go, but shouldn't I be able to detect some differences among these last three pins?
2. I guess I assumed most locks will normally only have one binding order. But, as I've mentioned, I've found two different ways to pick this paticular lock.
