This guide will walk you through the process step-by-step.


Tools You’ll Need

  • Paperclip or a small piece of wire
  • Drill and drill bits
  • Pliers
  • WD-40 or another lubricant


Step-by-Step Guide to Removing a Door Lock Cylinder Without a Key

1. Prepare the Door

Ensure the door is open and secured. If the door is closed and locked, you might need to unlock it first using other methods, such as a bump key or calling a locksmith.


2. Remove the Door Handle or Knob

Using a screwdriver, remove the screws from the door handle or knob. This will typically require removing the trim or faceplate to access the screws. Once the screws are removed, carefully take off the handle or knob.


3. Locate the Lock Cylinder

With the handle or knob removed, you should be able to see the lock cylinder. Depending on the type of lock, it may be held in place by a set screw or clip.


4. Release the Set Screw or Clip

If there is a set screw, use a screwdriver to loosen and remove it. If the cylinder is held in place by a clip, use pliers to remove the clip. Be careful not to lose these small parts.


5. Drill Out the Lock Cylinder (If Necessary)

If the lock cylinder cannot be removed by releasing the set screw or clip, you may need to drill it out. Use a drill bit that is slightly smaller than the cylinder itself. Start by drilling a pilot hole in the center of the cylinder, then gradually increase the size of the drill bit until the cylinder can be removed. Be cautious and wear safety goggles to protect your eyes from metal shavings.


6. Remove the Lock Cylinder

Once the set screw or clip is removed and the cylinder is drilled out (if necessary), you should be able to slide the lock cylinder out of the door. If it’s stuck, apply a small amount of lubricant such as WD-40 to loosen it.


7. Install the New Lock Cylinder

After removing the old cylinder, you can now install a new lock cylinder. Align the new cylinder with the hole, secure it with the set screw or clip, and reattach the door handle or knob.
