How To Drill Out A File Cabinet Lock?

To drill open a file cabinet lock, it is usually done to deal with situations such as lost keys or a broken lock. Below are some common steps and tips:

1. Prepare Tools
   Drill, carbide drill bit (1/8 to 1/4 inches), safety goggles, and gloves.

2. Locate and Mark
   Identify the center of the lock cylinder and mark it with a pencil. This ensures that the drilling hole remains aligned.

3. Begin Drilling
   Start drilling with a small drill bit (1/8 inch) at the marked point, applying firm pressure to avoid deviation.
   Once the hole reaches the bottom of the lock cylinder, gradually switch to a larger drill bit.

4. Enlarge the Hole
   Continue drilling with a larger drill bit until the lock cylinder is broken. If needed, gently tap the drill bit to help break the lock cylinder.

5. Break the Lock Cylinder
   Keep drilling or gently pry the lock cylinder with a tool (such as a screwdriver) until it cracks. The locking mechanism will loosen, and the file cabinet can be opened.

6. Handle the Lock
   After opening the file cabinet, if necessary, replace the lock to ensure it works properly for future use.
