With the right tools and knowledge, removing an interior doorknob is an easy job. Whether you’re updating hardware, fixing a malfunctioning knob, or prepping for a whole new door, our guide covers all the steps you need to know. We’ll walk you through removing various types of doorknobs, troubleshooting common issues, and tips for maintenance and replacement.
Tools Needed for Doorknob Removal
Having the right tools on hand will make the removal process smoother and help prevent damage to your door or the doorknob itself. Here’s what you’ll need.
Tools
- Flathead and Phillips head screwdrivers
- Allen wrench set
- Small hammer
- Pliers
- Paperclip or thin nail (for push-pin style locks)
Optional Tools for Difficult Removals
- Lubricating spray for stuck components
- Needle-nose pliers for reaching tight spaces
- Putty knife for prying loose trim pieces
Organizing Your Workspace To Remove a Doorknob
Before removing the doorknob, take time to prep your workspace. Clear the area around the door to give yourself enough room to work. We recommend laying down a drop cloth or towel to catch any falling screws or parts. Having a small container ready to hold the small screws you’re removing is also helpful.
Safety Precautions
- Wear safety glasses to protect your eyes from any small parts that may spring loose.
- If you’re working with an older door, be aware of potential lead paint hazards.
Step-by-Step Doorknob Removal Process
Follow these steps to remove your interior doorknobs safely and efficiently.
Locating the Mounting Screws
Examine the doorknob to find the mounting screws. They’re typically located on the interior side of the door, either on the knob’s base plate or along the edge of the door.
Removing Visible Screws
If you see exposed screws, use the appropriate screwdriver to remove them. Turn counterclockwise until the screws are completely loose.
Dealing With Hidden Screws
For doorknobs without visible screws:
- Look for a small slot or hole on the neck of the knob.
- Insert a flathead screwdriver or Allen wrench into this slot.
- Press firmly and turn the knob to release the hidden locking mechanism.
Detaching the Doorknob
Once the screws or locking mechanism are removed:
- Gently pull the interior knob away from the door.
- Remove the exterior knob by pulling it straight out.
- Slide out the spindle and any additional hardware.
Troubleshooting Doorknob Removal Common Issues
Even with the right tools and knowledge, you may encounter some challenges when removing a doorknob.
Here’s how to tackle stuck screws:
- Apply a penetrating oil and let it sit for a few minutes.
- Try using a manual screwdriver for better control and to avoid stripping the screw.
If you stripped your screws, try this:
- Use a rubber band between the screwdriver and screw head for better grip.
- If that fails, you may need to use a screw extractor tool.
Paint can sometimes seal the doorknob components together. Take these steps to fix the issue:
- Use a utility knife to score around the edge of the knob or faceplate carefully.
- Gently tap around the knob with a small hammer to break the paint seal.
Pro Tip: On any painted door more than 30 years old, assume lead paint may be present in one or more layers. Before scoring or tapping around hardware, spritz the area with water to keep down lead dust, lay plastic sheeting underneath to catch falling paint chips, and wear a respirator. When finished, wipe down the door with a liquid household cleaner, carefully wrap up and dispose of the debris, and wash your hands thoroughly.
Older doorknobs may have corroded parts that are difficult to separate. In these cases, you can:
- Apply a rust penetrant and allow it to soak in.
- Use pliers to grip and twist corroded parts loose carefully.
Replacing the Doorknob
Once you’ve successfully removed the old doorknob, you can replace the interior door or install a new knob.
Choosing a New Doorknob
When selecting a replacement doorknob, keep these considerations in mind:
- Do you need a left-handed or right-handed knob (for lever-style handles)?
- Which styles and finishes complement your home’s decor?
- Does the new doorknob match the hole pattern of your door?
Key Measurement: Before purchasing a replacement, measure the backset—the distance from the inner edge of the door to the center of the knob hole. This is the most critical dimension for ensuring your new hardware fits properly. For lever-style handles, note your door’s swing direction: stand outside and check which side the hinges are on. A door hinged on the left swings to the left, which determines whether you need a left- or right-hand lever. Entry sets with round knobs can typically be adapted to either swing, but levers are not as forgiving.
Installation Steps
Once you’ve got your new doorknob, follow these steps to install it.
- Insert the latch mechanism into the door edge.
- Place the exterior knob through the door.
- Attach the interior knob and secure it with mounting screws.
- Test the knob to check that it turns smoothly.
Special Cases
In some situations, you might encounter doors that require specially sized doorknobs. Always measure the dimensions of the previous doorknob assembly before purchasing a new one to avoid mismatches. Certain designs might also have additional decorative elements or require specific screw placements.
If you’re replacing knobs on antique wooden doors, consider reinforcing the wood around the hole to preserve durability.
Reversing Doorknob Orientation
Consider reversing your doorknob if you’re changing the door’s swing direction or if the current orientation is inconvenient or poses a safety issue.
How To Reverse a Doorknob
- Remove the doorknob following the steps outlined earlier.
- Rotate the latch mechanism 180 degrees.
- Reinstall the doorknob in the new orientation.
- Test for proper function.
When reversing a door’s swing, you’ll also need to reverse the striker so the bevel faces toward the jamb side. Note that a deadbolt is square, so it doesn’t need to be flipped — you only need to reverse the key side so it faces the new outside. As demonstrated on a recent TOH project, this is also a good time to change the direction of the door sweep while the door is down.
Additional Adjustments After Reversal
After reversing the doorknob, you may find that the latch doesn’t align perfectly with the strike plate. Adjusting the position of the strike plate or repositioning screws can help provide smooth operation.
If the door is not shutting correctly, check the hinge alignment as well. Reversing the doorknob may change how the door hangs so small tweaks might be necessary.
Professional Help: When To Call an Expert for Your Doorknob
While most homeowners can remove a doorknob on their own, we recommend calling a professional in the following situations:
- You encounter significant resistance or damage during the removal
- You’re dealing with antique or specialty hardware
- You’re uncomfortable with any step of the process
A professional locksmith or handyperson can often quickly resolve issues that might take a novice much longer to address.
From the TOH Archives: In one memorable project, homeowners Chloe and Nathan bought a house with an antique door featuring a dead bolt that didn’t work and a doorknob that just spun freely. They got quotes from multiple professionals who all recommended replacing the entire door — at a cost of thousands of dollars. Instead, a TOH expert was able to repair and replace just the lock components, preserving the door’s antique charm. As one of the team noted afterward: “It was very intricate, you know, it took some time and we had to go to the right place to get the right parts to fix it.”
Costs and Considerations
Hiring a professional can be a wise investment, especially for intricate or high-value hardware. Typical labor costs for professional doorknob removal or installation range from $30–$140 per hour, depending on your location and the complexity of the job.* Always request a detailed estimate before proceeding with any service.
For particularly valuable or historic doorknobs, consult a specialist who can preserve the hardware’s integrity during removal and installation.
