Replacing a door knob is a simple and rewarding DIY task that can enhance the appearance and functionality of your doors. Whether you’re upgrading for style or replacing a broken knob, this guide will walk you through the process of how to replace a doorknob step-by-step.

Step-by-Step Instructions:

1. Locate the Screws: Most door knobs are secured with screws on the interior side of the door. Use a screwdriver to remove these screws.
2. Detach the Door Knob: Once the screws are removed, gently pull both sides of the door knob apart and away from the door.
3. Remove the Latch Plate: Use the screwdriver to remove the screws securing the latch plate (the metal plate attached to the edge of the door) and pull the latch mechanism out of the door.
4. Check the Alignment: Measure the distance from the center of the door knob hole to the edge of the door (the backset) to ensure compatibility with your new door knob.
5. Clean the Area: Ensure the door and the holes are clean and free of any debris that might obstruct the new door knob installation.
6. Insert the New Latch: Slide the new latch mechanism into the hole on the edge of the door. Make sure the beveled side of the latch faces the direction the door closes. Secure it with screws.
7. Install the Exterior Knob: Position the exterior knob with the spindle (the rod that connects the two knobs) through the latch mechanism.
8. Attach the Interior Knob: Align the interior knob with the spindle and secure it by tightening the screws provided.
9. Test the Knob: Ensure the door knob turns smoothly and the latch engages and disengages properly when the knob is turned.
10. Remove the Old Strike Plate: If you are replacing the strike plate, use a screwdriver to remove the old one from the door frame.
11. Install the New Strike Plate: Position the new strike plate over the hole in the door frame where the latch engages. Secure it with screws.
12. Check Alignment: Close the door to ensure the latch aligns with the strike plate and the door closes securely.
13. Tighten Screws: Make sure all screws are tightly secured, but be careful not to overtighten and strip them.
14. Remove Tools and Debris: Clean up any tools and debris from the installation area.
15. Test the Door Knob: Give the door knob a final test to ensure everything is working correctly.
