Replacing a door knob may seem like a daunting task, but with the right tools and know-how, it can be completed in a matter of minutes. Whether your existing knob is loose, damaged, or simply outdated, a fresh knob can instantly refresh your door’s aesthetic and improve its functionality.
Understanding the different types of door knobs available is essential before you begin. The most common types are round knobs, lever handles, and deadbolts. Round knobs are traditional and come in a variety of materials, including brass, porcelain, and wood. Lever handles are modern and provide better grip, making them suitable for people with arthritis or limited dexterity. Deadbolts are primarily used for security purposes and can be installed alongside a traditional door knob or lever handle.
Once you have chosen the right type of door knob for your needs, it’s time to gather the necessary tools. You will need a screwdriver (Phillips or flathead depending on the type of screws used), a small nail or push pin, and optionally a locking wrench or pliers. With the right tools and a few simple steps, you can quickly and easily replace your door knob and give your door a new lease on life.
Gather Essential Tools and Materials
Replacing a door knob may seem like a simple task, but gathering the correct tools and materials is crucial for a successful repair. Here’s a detailed list of everything you’ll need:
Essential Tools:
1. Screwdriver: You’ll need a Phillips-head screwdriver for most door knobs, but some may require a flat-head or hex key. To ensure you have the right fit, inspect the screws on the existing door knob.
2. Socket Wrench: If the door knob has a set screw, you’ll need a socket wrench to remove it. The size of the socket should match the diameter of the screw.

Remove Old Door Knob and Spindle
Unscrew the Screws
Locate the two screws on the inside face of the doorknob plate. Use a screwdriver to carefully remove these screws.
Separate the Knob Halves
Gently pull the two halves of the doorknob apart. You may need to use a flathead screwdriver to pry them open if they are stuck.
Remove the Spindle
The spindle is the metal rod that connects the two doorknob halves. Pull the spindle out of the hole in the door and set it aside.
Remove the Knob Plate
With the spindle removed, you can now pull the doorknob plate off the door. Be careful not to damage the door or the plate.
Disassemble the Plate
The doorknob plate may be held together by additional screws or clips. Carefully remove these fasteners to disassemble the plate.
Remove the Handles
If the doorknob plate has handles, remove them by unscrewing the screws that hold them in place.
Additional Tips
– If the screws are stripped or damaged, use a pair of pliers to grip and remove them.
– If the spindle is stuck, try tapping it gently with a hammer to loosen it.
– Be sure to keep all the parts organized so that you can easily reassemble the new doorknob.
Install New Spindle
Now it’s time to mount the new spindle on the door.
In most cases, the spindle is fastened to the door with two screws that are secured into the door edge. Before inserting the spindle, apply a small amount of lubrication to the threads of the screws so that the proper tightness can be achieved without stripping them.
When choosing the screws for spindle attachment, you need to consider
- The thickness of the door
- The length of the screws
- The type of head they have
For example, if you have a 1-3/8-inch thick door, you should use 1-1/2-inch long screws with a pan head.
Here is a table that can help you select the right screws for your spindle:
| Door thickness | screw length | Screw head type |
|---|---|---|
| 1-3/8 inches | 1-1/2 inches | Pan head |
| 1-3/4 inches | 1-3/4 inches | Pan head |
| 2 inches | 2 inches | Pan head |
Once you have the correct screws, insert the spindle into the hole in the door edge. Align the holes in the spindle with the holes in the door and insert the screws. Tighten the screws until the spindle is snug against the door. Do not overtighten the screws, as this can damage the door or the spindle.
Attach New Door Knob
1. Slide half of the new doorknob onto the spindle. Make sure that the knob is oriented correctly, with the keyhole facing the correct direction.
2. Secure the knob with the screw provided. Do not overtighten the screw, as this can damage the knob.
3. Repeat steps 1 and 2 for the other half of the doorknob.
4. Install the Faceplate
The faceplate is the decorative plate that covers the screws and spindle on the door. To install the faceplate:
a) Slide the faceplate over the spindle until it is centered between the two doorknobs.
b) Secure the faceplate with the screws provided. Again, do not overtighten the screws.
c) Check the alignment of the faceplate. It should be flush with the surface of the door and perpendicular to the spindle.
d) If the faceplate is not aligned correctly, remove the screws and adjust the position of the faceplate before re-tightening the screws.
5. Test the doorknob to make sure that it is installed correctly and operates smoothly.
Set Screw and Tighten Securely
Once the old doorknob is removed, it’s time to install the new one. Start by inserting the new doorknob into the spindle. Make sure that the doorknob is facing the correct direction. There is usually a small notch or flat spot on the spindle that indicates which way the doorknob should face.
Once the doorknob is in place, tighten the set screw. The set screw is usually located on the side of the doorknob. Use a screwdriver or Allen key to tighten the set screw. Be sure to tighten the set screw securely, but do not overtighten it.
If you have a doorknob with a separate rose plate, you will need to attach the rose plate to the door before installing the doorknob. To attach the rose plate, simply place the rose plate over the hole in the door and screw it into place.
Once the rose plate is attached, you can install the doorknob. To install the doorknob, simply insert the doorknob into the hole in the rose plate and tighten the set screw.
Once the doorknob is installed, test it to make sure that it is working properly. The doorknob should turn smoothly and should not wobble. If the doorknob is not working properly, you may need to adjust the set screw or the rose plate.
Replace Strike Plate and Adjust as Needed
Before replacing the strike plate, check its alignment:
– Open the door and examine the strike plate against the door jamb.
– The door should fully close, and the latch should securely extend into the strike plate.
If the alignment is incorrect:
– Mark the location of the strike plate on the jamb using a pencil.
– Remove the old strike plate and fill any gaps in the jamb with wood filler or caulk.
– Reattach the strike plate using the screws provided.
– Adjust the hole in the strike plate until the latch fits snugly.
| Adjustment | Direction |
|---|---|
| Latch is too high | Move strike plate up |
| Latch is too low | Move strike plate down |
| Latch is too far in | Move strike plate towards door |
| Latch is too far out | Move strike plate away from door |
Once the strike plate is aligned:
– Check that the door opens and closes smoothly.
– If the latch is difficult to engage, adjust the strike plate again until it works properly.
