Choosing the Right Door Knob and Lock
Select a door knob and lock that fit the style and security requirements of your home. Consider whether you need a privacy lock for bedrooms or a keyed entry for exterior doors. Check the door’s thickness and backset size to ensure compatibility.
Step-By-Step Instructions to Remove the Old Door Knob
Safely Removing the Existing Door Knob
Gently loosen and remove the screws on the door knob’s plate using your screwdriver. Pull the knobs apart from each side of the door. If they are stubborn, wiggle them gently to release the mechanism without damaging the door.
Dealing with Stubborn Screws and Hardware
If screws are stripped or stuck, apply a penetrating oil, allow it to soak in, and then try again with a screwdriver. For severely stripped screws, use a screw extractor for removal.
Measuring and Preparing Your Door for a New Knob and Lock
How to Measure Your Door for a New Knob
Measure the diameter of the existing knob hole and the distance from the edge of the door to the center of the hole (backset). These measurements help you buy the correct size replacement.
Preparing the Door for Installation
If the new knob requires a larger hole, mark the additional circumference needed and use a hole saw attached to your drill to enlarge it. Sand any rough edges for a clean finish.
Installing the New Door Knob and Lock Mechanism
Attaching the New Latch and Strike Plate
Insert the new latch into the side of the door, making sure the tapered side faces the direction the door closes. Secure the latch with screws, then align and install the strike plate on the door jamb.
Fitting the Door Knob and Ensuring Proper Alignment
Slide the exterior part of the knob through the latch mechanism. Attach the interior knob and align them. Insert and tighten the connecting screws ensuring the knob turns freely without binding.

Securing and Tightening All Components
