Yale Y210/51 padlock gutted
My findings were a bit different! Here is the lock:
And the core removed:
The core has 6 pin chambers so you can add an extra pin if you like... the key profile is identical to that of the X6 cylinder so you could pin this up to work with your front door key if you liked. Pretty nifty!
It's worth mentioning that I tried an X5 key aswell, but it didn't fit - it's actually a slightly different shape and also a bit larger, but at a glance they look identical so mixing them up is pretty easy. Anyway... you'll notice that the springs alternate in height, so we have ourselves some balanced drivers in here.
And here they are (not in order):
And the key pins:
You'll notice there is a slight inwards taper at the top of each pin... this makes oversetting pins very easy to do. Here's a macro shot:
At first I was going by micks findings and avoiding false sets like the plague because I assumed it was the chamfer and "false set" translated to "overset"... nomatter how careful I was, I couldn't get it open. Now I know why! I put it back together and got straight back to picking it, but strangely I'm still not having much luck.
I'm putting that down to lack of concentration though. I'm gonna have to pay a lot more attention if I want to crack this thing... so when I sit down with it again, if something clicks out of false set I need to make a note of which pin it is and take care not to push on it any more, cos at the moment I'm not really paying attention to that stuff. I never really had to before, since with normal key pins it doesn't matter if you apply a bit of pressure on them when they're set.
This will be a good learning experience for when it comes to serrated key pins like the ones in that bastard kryptonite. I'll be posting again when I get this sucker open. Certain levels of excitement are to be expected.
