How to Open a Damaged File Cabinet Lock

Quck answer

If you have a broken file cabinet lock and need to unlock it, there are a few methods you can try. First, you can try using a locksmith’s tool called a lock pick to manipulate the lock and open it. Another option is to use a drill to remove the lock cylinder and gain access to the cabinet. If these methods don’t work, you may need to call a professional locksmith to help you unlock the broken file cabinet lock. Remember to always proceed with caution and follow any safety precautions when attempting to unlock a broken lock.


If you have misplaced the key to your locked filing cabinet and need to gain access to it, you have two options. You can either hire a locksmith to create a new key for you, or you can drill out the lock to unlock the cabinet. Although drilling the cabinet will render the lock unusable, it will allow you to open the filing cabinet.

Step 1

Insert a 1/8-inch drill bit into your hand drill and position the tip of the drill bit in the center of the keyhole on the lock.

Step 2

Drill a hole directly through the lock. If the drill bit starts to produce smoke, spray it with a small amount of water from a water bottle to keep it cool. The locks used on filing cabinets are made of relatively soft metal, so overheating the bit should not be a concern.

Step 3

Insert the blade of a screwdriver into the hole and attempt to rotate the lock counterclockwise. If the lock turns, it will unlock the filing cabinet. If the lock does not turn, increase the size of the drill bit and repeat steps 2 and 3 until the lock does turn.
