How to Replace a Door Handle or Knob
Replacing a door handle or knob isn’t just a stylish update—it’s a handy DIY project that anyone with a bit of patience and a screwdriver can handle. If your current handle is loose, wobbly, outdated, or being held together by sheer willpower, don’t sweat it. Swapping it out is easier than you think. This guide walks you through each step with clear instructions, helpful tips, and just enough humor to make the process more enjoyable.
Let’s dive in and give that door the makeover it deserves!
What You’ll Need
Before you start, gather all your tools and materials. Having everything on hand makes the process smoother and quicker.
A new door handle or knob set (make sure it matches your door type)
A Phillips-head or flat-head screwdriver (depending on your current hardware)
Measuring tape or ruler
Doorstop or wedge to keep the door still

Step 1: Prep the Door
Use a wedge or a sturdy doorstop to hold the door slightly open. This gives you access to both sides without the door swinging around and turning a simple job into an accidental workout.
Step 2: Remove the Old Handle
Time to say farewell to the old hardware—respectfully, of course.
1. Locate the Screws
Check the faceplate of the handle for visible screws. If you don’t see any, there might be a decorative cover hiding them. Look for a tiny slot or notch—use a small flathead screwdriver or a paperclip to pop it off.
2. Unscrew and Remove the Handle
Unscrew the handle from both sides. Gently pull them off the door. You’ll see a metal rod, called the spindle, which connects the two sides. It should come out attached to one of the handles.
3. Remove the Latch
Now, look at the edge of the door. Unscrew the latch plate and slide the latch mechanism out of the hole.
Step 3: Measure Everything
Before installing your new handle, grab a measuring tape and confirm that everything matches up.
Bore hole diameter – The circular hole in the face of the door
Backset – Distance from the edge of the door to the center of the bore hole (usually 2⅜” or 2¾”)
Door thickness – Most doors are 1⅜” or 1¾” thick
Matching your new hardware to these dimensions is key. If they don’t match, you might need an adapter or a different handle.
Step 4: Install the New Latch
Insert the new latch into the hole on the edge of the door. Make sure the slanted side of the latch bolt is facing in the direction the door closes—this helps the latch catch properly.
Screw it into place firmly but don’t overtighten.

Step 5: Install the New Handle or Knob
Now for the satisfying part: installing the shiny new hardware.
1. Insert the Spindle
Slide the spindle through the latch mechanism from one side of the door. It should poke through to the other side.
2. Attach the Handles
Align both sides of the new handle with the spindle and the screw holes. Gently tighten the screws, being careful not to overdo it. You want the handle to be secure, not squeaky-tight.
3. Test It
Before final tightening, test the handle to make sure it turns smoothly and the latch moves freely. Adjust as needed.
Step 6: Update the Strike Plate
If your new handle came with a matching strike plate (the metal bit on the door frame), it’s a good idea to swap it out. Unscrew the old one and install the new one in the same spot, making sure it aligns with the latch.
If the latch doesn’t catch properly, adjust the position slightly.
Step 7: Finishing Touches
You’re almost there—just a few final tweaks.
Tighten all screws securely but not overly tight
Snap on any decorative cover plates
Open and close the door a few times to ensure everything operates smoothly
Wipe down the handle for fingerprints (yes, you’re fancy now)
Extra Tips (Because You’re Leveling Up)
Pick the right style: Lever handles are easier for kids, elderly folks, or anyone with hand strength issues. Knobs are often more pet-proof.
Hang onto old parts: Save screws and hardware in a labeled bag—you might thank yourself later.
Document your victory: A before-and-after photo might just earn you some well-deserved bragging rights.
