What You’ll Need

Before we dive into the steps, let’s discuss the tools and materials you’ll need for this project:

  • Doorknob Kit: Includes the doorknob, latch, strike plate, and hardware.
  • Phillips Screwdriver: Essential for most kits.
  • Slotted Screwdriver: Needed for some kits to remove casings.
  • Drill (Optional): Can speed up the process.
  • Extension Bit (Optional): Helps reach screws around the doorknob.

Step-by-Step Instructions

1. Removing the Old Doorknob

First, we need to remove the old doorknob. Use your Phillips screwdriver to unscrew the doorknob screws. If you're using a drill, an extension bit will help clear the distance of the door handle. Doorknob screws are usually long, considering the thickness of a door is about one and three-quarters inches.

Once the screws are removed, pull the doorknob from both sides, and it should slide out easily.

2. Removing the Latch Plate

Next, remove the latch plate by unscrewing the two screws on the edge of the door with your Phillips screwdriver. Once loosened, slide out the latch plate.

3. Removing the Striker Plate

Remove the striker plate by unscrewing the two screws that hold it to the doorframe. Using a drill can make this process quicker. Be careful not to drop the screws!

4. Installing the New Doorknob

Now, let’s see what comes in your new doorknob kit. You should have the doorknob, a bolt, a strike plate, some hardware, an inset for the bolt, and keys if it has a lock.

5. Installing the Latch and Bolt

Insert the latch and bolt into the edge of the door, ensuring the bevel faces the door jamb. Secure it with the two screws provided.

6. Installing the Doorknob

Insert the external doorknob (the one with the key if applicable) first. Align it with the half-circle shape of the latch. Align the other side of the doorknob and fit them together so they are snug. Insert the two screws and tighten them. Remember, this might take some time due to the door's thickness.

7. Installing the Striker Plate

Attach the new striker plate to the doorframe. Make sure the little tab inside the striker plate is positioned correctly against the door's striking side. Secure it with the screws provided.

8. Testing the New Doorknob

Finally, test your new doorknob. Turn the handle to ensure it locks and unlocks smoothly. If your doorknob has a lock, test the key by locking and unlocking the door.

And that’s it! You’ve successfully replaced your old doorknob with just a Phillips screwdriver.
