ok then, this is not a hard one to defeat
the springs aren't too strong, but it can contain anywhere up to 4 spool pins, my particular 220 has none, but you may need some slimline picks, and i have found that a hook works well on 220's
after opened it has a hex screw you need to take out.
things to remember:
1.don't dismantle whole padlock
2.remember to put back the twoo support pins that are in the cylinder housing.
good luck
