Step 1: Remove the Old Doorknob

Old doorknob

First, you need to remove the old doorknob. To do this, locate the screws on the doorknob faceplate (the part that covers the hole in the door). Use a Phillips screwdriver to unscrew these screws and remove the faceplate.

Next, locate the screws that hold the doorknob in place. These are usually located on the sides of the knob. Use a Phillips screwdriver to unscrew these screws and remove the doorknob from the door.

Step 2: Remove the Latch

Once you have removed the doorknob, you can remove the latch from the edge of the door. This is the part that keeps the door closed. Locate the screws that hold the latch in place and use a Phillips screwdriver to unscrew them.

You should now be able to remove the latch from the door. If the latch is stuck, you may need to use a flathead screwdriver to pry it loose gently.

Step 3: Install the New Latch while Ensuring the Correct Backset

Install the new latch while ensuring the correct backset

Before installing the new latch, ensuring the correct backset is essential. The backset is the distance between the door’s edge and the doorknob’s center. It’s important to use the correct backset, which is usually 2 3/8 or 2 3/4 inches, depending on your door.

To determine the correct backset size for your new doorknob, you can measure the distance from the edge of the door to the center of the existing doorknob’s hole. Alternatively, you can measure the distance from the edge of the door to the center of the latch bolt, which is part of the doorknob that extends into the door jamb when the door is closed.

Install the new latch while ensuring the correct backset

Once you’ve determined the correct backset, slide the latch into the hole in the edge of the door while aligning it with the backset. Push the latch in until it’s fully seated in the hole, and use screws to secure it in place if necessary.

Step 4: Install the New Doorknob

Now it’s time to install the new doorknob. Start by inserting the spindle (the metal rod that connects the two knobs) into the latch. Make sure the spindle is centered in the latch and extends through both sides of the door.

Next, insert one of the new knobs onto the spindle. Align the knob so that the screw holes on the knob line up with the holes on the spindle. Use the screws provided in your doorknob kit to attach the knob to the spindle. Tighten the screws firmly, but be careful not to over-tighten them.

Repeat this process for the other knob.

Step 5: Install the Faceplate and Strike Plate

The final step is to install the faceplate and strike plate. The faceplate covers the hole in the door where the latch is installed, while the strike plate is the metal plate that is screwed into the door frame and receives the latch.

Install the faceplate and strike plate

Align the faceplate over the hole and use the screws provided in your doorknob kit to attach it to the door. Then, align the strike plate over the hole in the door frame and use the screws provided to attach it to the frame.

Make sure both the faceplate and strike plate are aligned properly and securely attached to the door and frame.

That’s it! You have successfully replaced your doorknob. Take a moment to test the new doorknob to make sure it works properly. If everything is functioning as it should, you’re done!
