Sorry if i post twice i'm new and dont my previous post ??
To be brief it happened a couple of time with different padlock and eurolock that i feel like only setting the last or the two last pin open the lock. I dont apply any pressure on the wrench while i insert the pick and i'm pretty sur that i dont accidently set the front pins. It seem like some pins are fake like if they dont have driver pin to block.actually it cant be that i feel the pressure.
Any explanation ?
