Lets try this again - American Lock 5200

Hey thanks. Our office is missing some keys to file cabinets, and people keep 'accidently' locking them, so i end up picking about 3 cabinets per week. Obviously, they're low security locks, so I open them in less than 3 seconds. Most padlocks are a breeze at this point, so the American Lock was my first big goal. I wonder what else i can pick

Ok, here's my tip. Overlift all of the pins at once with the back of a hook pick, hold firm tension, remove the pick, flip it back so the hook faces the pins, now use it to go under each pin while slowly letting off the tension and work each stack until they are all properly set. This method has helped me a lot to overcome the serrated pins.

Excellent advice, I call this "reverse picking" since your are allowing the pins to drop as opposed to lifting them.

We all know the real weakness of this lock is the cylinder retaining screw setup... buy stock in Dremel.
