  1. 1

    Bend two paper clips until they are long and straight with a hook at the end.

  2. 2

    Slide the hooked end of the paper clip into the very top of the lock. Most locks used for filing cabinets have four pins. Apply pressure to the uppermost pin. You will feel the pin move and snap into the open position. If you don’t feel the pin snap you are working with a lock that is double sided. You will need a ball pick to move both pins at the same time.

  3. 3

    Slide the ball pick into the lock. Move the ball pick around until you hear the pins snap.

  4. 4

    Move down to the next lowest pin. Use the paper clip or the ball pick to move that pin out of the way.

  5. 5

    Repeat the process with the remaining two pins.

  6. 6

    Insert one paper clip at the top of the lock. Insert the second paper clip in the bottom. Move both clips together to turn the lock and open the filing cabinet.

Tips and warnings

  • If the keys are lost forever you will need to replace the lock on the filing cabinet. Replacement locks can be ordered online and you can easily change out the lock with a few simple tools.
