Getting Started
Installing a doorknob may seem like a daunting task, but with the right tools and a step-by-step guide, it can be accomplished with ease. Before you begin, gather the necessary materials:
- New doorknob and latch
- Screwdriver (Phillips or flathead, depending on the doorknob)
- Tape measure or ruler
- Pencil or marker
- Drill (optional, for creating a new hole if necessary)
- Safety glasses
Safety first! Wear safety glasses when using power tools. Double-check that the doorknob and latch you have purchased are compatible with your door. Measure the distance between the edge of the door and the center of the existing hole. This measurement will determine the backset of the new doorknob. The backset is typically 2-3/8 inches or 2-3/4 inches, but it can vary depending on the door and doorknob.
| Backset Measurement | Suitable Doorknob |
|---|---|
| 2-3/8 inches | Standard doorknobs |
| 2-3/4 inches | Drive-in doorknobs |
Gathering Materials
Before embarking on your doorknob installation project, it is imperative to gather all the necessary materials. Here is a comprehensive list of the essential tools and components you will need:
Tools

Removing the Old Doorknob
Before installing a new doorknob, you must first remove the old one. This process is generally straightforward, but it can vary slightly depending on the type of doorknob you have.
Step 1: Remove the Set Screws
Most doorknobs are secured with two set screws that are located on the inside edge of the doorknob. To remove these screws, you will need a Phillips head screwdriver. Simply insert the screwdriver into the screw and turn it counterclockwise until it is loose. Once both screws are removed, you can pull the doorknob straight off of the spindle.
Step 2: Remove the Latch Assembly
Once the doorknob is removed, you need to remove the latch assembly. The latch assembly is the part of the doorknob that engages with the strike plate on the doorframe. To remove the latch assembly, insert a flathead screwdriver into the slot on the edge of the latch assembly and turn it counterclockwise. Once the latch assembly is loose, you can pull it straight out of the door.
Step 3: Remove the Strike Plate
The strike plate is the metal plate that the latch assembly engages with on the doorframe. To remove the strike plate, simply unscrew the screws that are holding it in place. Once the screws are removed, you can pull the strike plate straight off of the doorframe.
Here is a table summarizing the steps for removing an old doorknob:
| Step | Description |
|---|---|
| 1 | Remove the set screws. |
| 2 | Remove the latch assembly. |
| 3 | Remove the strike plate. |
Installing the New Latch
Once the old latch has been removed, the new latch can be installed. The new latch will typically come with all of the necessary hardware, including screws, a strike plate, and a dust cover.
- Align the new latch with the hole in the door frame. The latch should be oriented so that the door opens in the correct direction.
- Secure the latch to the door frame using the screws provided. Ensure that the latch is securely fastened.
- Install the strike plate on the door jamb. The strike plate should be positioned so that the latch will engage with it when the door is closed.
- Install the dust cover on the latch. The dust cover will help to keep the latch clean and free of debris.
Here is a summarized table of some differences between the new and old latch:
| Feature | Old Latch | New Latch |
|---|---|---|
| Material | Steel | Brass |
| Finish | Painted | Polished |
| Durability | Less durable | More durable |
| Cost | Less expensive | More expensive |
Mounting the New Doorknob
Now that the holes are prepared, it’s time to mount the new doorknob.
- Insert the spindle: Align the spindle with the holes in the door and insert it through both sides.
- Attach the handles: Slide the handles onto the spindle, positioning them in the desired orientation.
- Tighten the set screws: Locate the small set screws on the handles and tighten them using an Allen wrench to secure the handles.
- Align and tighten the escutcheons: Place the escutcheons (decorative plates) over the handles and align them correctly. Tighten the screws to hold them in place.
- Test the installation: Grip the handles and turn the doorknob to ensure it operates smoothly and latch securely. If necessary, adjust the spindle or handle position to achieve proper alignment and functioning.
Tips for Troubleshooting:
| Issue | Solution |
|---|---|
| Doorknob is loose | Tighten the set screws on the handles. |
| Doorknob is not latching | Adjust the strike plate or spindle position. |
| Handles are not aligned | Loosen the set screws, reposition the handles, and tighten again. |
Tightening the Screws
Once the screws are inserted, you’ll need to tighten them to secure the doorknob in place. To do this, use a screwdriver to turn the screws clockwise until they are snug.
Be careful not to overtighten the screws, as this can damage the doorknob or the door. If you’re not sure how tight the screws should be, err on the side of caution and tighten them just until they are snug.
Here are some additional tips for tightening the screws:
- Use a screwdriver that fits the size of the screws snugly.
- Turn the screwdriver slowly and evenly.
- If the screws start to bind, don’t force them. Instead, back them out a bit and then try again.
- Once the screws are tight, check to make sure that the doorknob is securely attached to the door.
Screw Length Considerations
| Door Thickness | Screw Length |
|---|---|
| 1-3/8″ to 1-3/4″ | 2″ |
| 1-3/4″ to 2″ | 2-1/4″ |
| 2″ to 2-1/4″ | 2-1/2″ |
Attaching the Trim Plates
Once the latch and strike plate are installed, it’s time to attach the trim plates. These decorative pieces cover the screws holding the latch and strike plate in place, giving the doorknob a finished look.
Start by aligning the trim plate with the latch or strike plate. Make sure the holes in the trim plate line up with the screws holding the latch or strike plate in place.
Next, insert the screws through the holes in the trim plate and into the corresponding holes in the latch or strike plate. Tighten the screws until the trim plate is securely attached.
Repeat these steps for the other trim plate. Once both trim plates are attached, your doorknob is installed and ready to use.
Here are some additional tips for attaching the trim plates:
- Use a screwdriver that is the correct size for the screws. Using a screwdriver that is too small or too large can damage the screws or the trim plates.
- Don’t overtighten the screws. Overtightening the screws can damage the trim plates or the latch or strike plate.
- If the trim plates are loose, try tightening the screws slightly. If the trim plates are still loose, you may need to replace the screws.
| Doorknob Type | Screwdriver Size |
| Standard | Phillips #2 |
| Mortise | Slotted 1/4″ |
Installing the Lock Cylinder (if applicable)
If your doorknob includes a lock, you’ll need to install the lock cylinder before mounting the doorknob. Here’s how:
-
Insert the key into the lock cylinder and turn it to the unlocked position. This will align the pins inside the cylinder.
-
Using a screwdriver, remove the screws that hold the lock cylinder in place.
-
Carefully pull the lock cylinder out of the doorknob.
-
Align the new lock cylinder with the holes in the doorknob and insert it into the doorknob.
-
Secure the lock cylinder with the screws.
-
Insert the key into the lock cylinder and turn it to the locked position.
-
Remove the key and try opening and closing the door to make sure the lock is working properly.
-
Reattach the doorknob to the door, making sure to align the spindle hole in the doorknob with the spindle hole in the door.
Testing the Doorknob
Before you finalize the installation, it’s crucial to thoroughly test the doorknob to ensure it’s functioning optimally. Here’s a detailed checklist to guide you through the testing process:
- Operation: Operate the doorknob by turning it clockwise and counterclockwise. Check if it rotates smoothly without any resistance or binding.
- Latching: Verify that the latch engages properly when the door is pushed closed. There should be a distinct “click” sound indicating a secure connection.
- Alignment: Ensure the strike plate is aligned correctly with the latch. The latch should fit snugly into the strike plate without any gaps.
- Clearance: Check if the doorknob provides adequate clearance from the door frame. There should be enough space between the knob and the frame to prevent interference when opening or closing the door.
- Friction: Test the doorknob for friction by rotating it multiple times. It should move freely with minimal resistance.
- Security: Examine the doorknob for any signs of damage or weakness. Ensure the screws are tightened securely and there are no loose components.
- Backset: Verify that the backset (the distance from the edge of the door to the center of the doorknob hole) is correct for your door type.
- Door Thickness: Check if the doorknob is suitable for the thickness of your door. If the doorknob is too long, it may protrude beyond the door’s edge, creating a safety hazard.
- Strike Plate Installation: Ensure the strike plate is properly installed into the door frame. It should be flush with the surface and not exceed the thickness of the door.
Troubleshooting
1. The doorknob doesn’t turn smoothly.
Possible causes:
- The doorknob is not properly aligned with the spindle.
- The spindle is bent.
- The latch is catching on the strike plate.
