1) Gum in the lock. oldie but GOODIE!    2) Solder in the lock: Just melt a little solder into the lock. It'll       freeze up some of the pins, and change the shape of the valleys    3) Super Glue: Go to Radio Hack and buy some one minute epoxy, or a       container of super glue. Then fill the lock. This works REALLY       well on cars.       4) Paper: If you wedge a LITTLE paper in the right spot, you can make       the tumblers of the lock change position.    5) Sulphuric Acid: Just put a few drops in the lock, and PRESTO!, you've       changed the configuration of the lock.
