How do you clutch the pins out of a padlock?
Answers: You need what they call a ' Core Key ' that removes the core. That's what they use to re-key a lock by removing prehistoric pins and replacing those with the correct pins.
Or you can use a good cumbersome duty drill and bit to drill out the key slot on the bottom of grove. That will let the pins dive out..but the lock is pretty much worthless at that point.
