How to Remove an Interior Doorknob: Step-by-Step Guide

Removing an interior doorknob is a common home improvement task that can be accomplished with basic tools and a little know-how. Whether you’re replacing an old doorknob, upgrading your door hardware, or simply need to access the door for repairs, this guide will walk you through the process from start to finish. We’ll cover the tools you’ll need, the step-by-step removal process, common issues you might encounter, and expert tips to ensure a smooth experience.

Tools and Materials Needed

• Screwdriver (Phillips or flathead, depending on your doorknob)
• Utility knife
• Chisel
• Hammer
• Combination square
• Measuring tape
• Pencil
• Wood shims (optional)

Step 1: Prepare the Door

Before you begin removing the doorknob, make sure the door is closed and secure. This will prevent the door from swinging open or closing unexpectedly while you work. If the door is heavy, consider having a helper support it to avoid any accidents.

Step 2: Remove the Doorknob

The first step in removing an interior doorknob is to unscrew the doorknob from both sides of the door. Most doorknobs are held in place by screws located on the interior side of the door. Use a screwdriver to remove these screws, then gently pull the doorknob off the door.

For some doorknobs, you may need to remove a set screw located on the side of the knob. Use a small screwdriver to loosen the set screw, then pull the knob off the door.

Step 3: Remove the Latch Mechanism

Once the doorknob is removed, you’ll need to remove the latch mechanism from the edge of the door. The latch mechanism is typically held in place by two screws. Use a screwdriver to remove these screws, then gently pull the latch mechanism out of the door.

Take note of how the latch mechanism is assembled, especially if you plan to reinstall it later. This will help you reassemble the doorknob correctly when you’re ready to install a new one.

Step 4: Detach the Hinges

If you need to remove the entire door, you’ll need to detach the hinges. Start by removing the hinge pins. Begin with the bottom hinge and work your way up. Ask a helper to support the door as you remove the final pin to prevent the door from falling.

Once the hinge pins are removed, carefully lift the door off the hinges and set it aside. If you’re only removing the doorknob, you can skip this step.

Step 5: Prepare the New Door (If Replacing)

If you’re replacing the door, start by preparing the new door for installation. Place the new door across a pair of sawhorses and lay the old door on top, aligning the top end and lockset edge perfectly. Trace around the old door with a pencil to mark where the new door needs trimming.

Use a combination square to transfer the hinge locations from the old door to the new one. Use a utility knife instead of a pencil when outlining hinge mortises for more accurate lines.

Step 6: Chisel Out Hinge Mortises

Stand the door on its edge with the hinge layouts facing up. Use a chisel and hammer to outline each mortise. Make a series of closely spaced cuts that are as deep as the hinge is thick. Hold the chisel at a low angle and tap it to remove waste wood.

Test-fit the hinge leaf to ensure it sits flush with the door edge. If you accidentally cut a mortise too deep, place a thin wood or cardboard shim behind the hinge leaf to adjust the fit.

Step 7: Install the Lockset

Mark the point at which the strike plate hole meets the door edge. Use the lockset’s template to mark destinations for the doorknob and latch. Drill the doorknob hole with a 2 1/8-inch hole saw. Cut the latch edge bore with a 7/8-inch spade bit.

Trace around the latch assembly and chisel out a shallow mortise. Screw the latch to the door and install the doorknobs.

Step 8: Adjust the Strike Plate

Close the door and observe how the latch aligns with the strike plate. Loosen the strike plate screws and adjust the positioning if necessary. Tighten the screws and test the door closure again. Bend the strike plate’s tab slightly for minor adjustments.

Common Issues and Troubleshooting

• Stuck Doorknob: If the doorknob is stuck, try using a lubricant like WD-40 to loosen it. If that doesn’t work, you may need to use a screwdriver to pry it off.
• Stripped Screws: If the screws are stripped, use a screw extractor or drill out the old screws and replace them with new ones.
• Door Won’t Close Properly: If the door won’t close properly after removing the doorknob, check the alignment of the hinges and strike plate. Adjust as needed.

Expert Tips

• Always use the correct size screwdriver to avoid stripping the screws.
• Take your time when chiseling out mortises to ensure a clean, precise fit.
• Test-fit all hardware before final installation to avoid mistakes.
• Prime and paint the top and bottom of the door to block out moisture and prevent warping.
