I have two, No. 3 masterlock padlocks that I have unsuccessfully been trying to pick. I am using two different picks that I made myself, which are definitely capable of working as I have picked other, easier locks. These locks have had a lot of wear and tear on them from the weather, excessive picking and bumping, could this be the reason I can't pick them and what should I do to improve my skills, I am new at picking but very familiar with how a lock works and a pretty good bumper.
Thanks
