Replacing an old knob with a modern lever is one of the most effective ways to upgrade the look of your home. Whether you are remodeling a bedroom or updating a bathroom, learning how to install a door lever handle can save you money on contractor fees. This process is generally straightforward, but it requires attention to detail to ensure the latch functions correctly. In this guide, we will explore the specific tools needed, the preparation steps, and the installation process for various types of interior door lever handles.
Many homeowners are switching to lever door handles because they offer better accessibility than traditional round knobs. A door handle lever is much easier to operate, especially for children, the elderly, or anyone with limited hand strength. You simply push down rather than grip and twist. Beyond functionality, interior door lever handles provide a sleek, contemporary aesthetic that can instantly modernize a hallway or living space.
When you browse options for a new door handle lever, you will notice a variety of finishes and styles. From matte black to brushed nickel, the right lever door handles can complement your existing decor perfectly. Durability is another key factor. A high-quality door handle lever is built to withstand thousands of cycles, ensuring that your doors open smoothly for years to come.
Before you begin installing your new interior door lever handles, you must gather the correct tools. Having everything ready prevents frustration during the installation process. Most lever door handles come with the necessary mounting hardware, but you will need your own tools to complete the job.
Tool Name | Purpose |
|---|---|
Phillips Head Screwdriver | Used for tightening most mounting screws on the door handle lever. |
Flathead Screwdriver | Helpful for prying off old rosette plates or adjusting the latch faceplate. |
Tape Measure | Essential for checking the backset measurement for your lever door handles. |
Power Drill (Optional) | Speeds up screw removal but must be used carefully to avoid stripping threads. |
Chisel | Necessary if you need to deepen the mortise on the door edge for the latch plate. |
Hammer | Used with the chisel or to gently tap the latch into place. |
Pencil | Used for marking drill holes or outlining the latch plate on the door edge. |
The first step in upgrading to interior door lever handles involves removing the existing hardware. How do you take off the old knob? Start by locating the screws on the interior side of the door. Use your screwdriver to unfasten them. Once the screws are out, the knobs on both sides should pull apart easily.
Next, you must remove the old latch mechanism. Locate the two screws on the edge of the door holding the latch plate in place. Unscrew them and pull the entire latch assembly out of the hole. If the old latch is stuck, you can insert a screwdriver shaft through the large bore hole to push it out. With the old hardware gone, you now have a clean slate to install your new lever door handles.
One of the most critical steps when installing a door handle lever is determining the backset. What is a backset? It is the distance from the edge of the door to the center of the large bore hole. Most residential doors in the United States use a backset of either 2-3/8 inches or 2-3/4 inches.
Your new interior door lever handles likely come with an adjustable latch that fits both sizes. However, you must confirm the measurement before proceeding. Use your tape measure to check the distance. If your latch is not set to the correct length, the spindle will not align properly, and the door handle lever will not operate the latch bolt. Adjust the latch mechanism on your new lever door handles according to the manufacturer's instructions to match your door's backset.
With the backset determined, how do you install the latch? This component is the heart of your door handle lever system. Insert the latch into the hole on the edge of the door. The beveled side of the latch bolt must face the direction the door closes. If it faces the wrong way, the door will not latch when you push it shut.
Once the latch is inserted, check the faceplate. If your door has a chiseled rectangular recess, use the rectangular faceplate supplied with your interior door lever handles. If the door edge is flat with only a round hole, you may need to use a drive-in collar instead of the rectangular plate. Secure the latch with the two small wood screws provided. Ensure the faceplate sits flush with the door edge so it does not obstruct the door frame.
Now comes the main event: placing the lever door handles onto the door. Which side goes first? Typically, you start with the exterior chassis—the side with the spindle (or the keyed cylinder if it is a locking unit). Slide the spindle through the square hole in the latch mechanism you just installed.
While holding the exterior door handle lever in place, align the interior handle on the opposite side. The mounting holes on the interior rosette should line up with the screw posts extending from the exterior unit. It helps to have a second person hold the exterior lever while you align the interior side, especially with heavy-duty interior door lever handles.
Once the two halves of the door handle lever are aligned, how do you lock them together? Insert the long machine screws through the holes on the interior rosette. Thread them into the posts of the exterior handle by hand first to ensure they are not cross-threaded.
Use your Phillips screwdriver to tighten the screws. Do not overtighten them immediately. Tighten each screw a little bit at a time, alternating between top and bottom (or left and right). This ensures the lever door handles sit straight on the door surface. Once they are snug, test the operation. Push the door handle lever down to see if the latch retracts smoothly. If it sticks, loosen the screws slightly, adjust the alignment, and retighten.
The installation of lever door handles is not complete without the strike plate. What is the strike plate? It is the metal plate attached to the door jamb that catches the latch bolt. Even if the old strike plate looks similar, it is best to replace it to match the finish of your new door handle lever. Remove the old strike plate by unscrewing the two screws. Place the new plate into the mortise on the jamb. Ensure the opening aligns with the latch bolt on the door. Screw the new strike plate into place. Close the door to test the fit. The latch from your door handle lever should click securely into the strike plate without rattling. If the door rattles, you may need to adjust the small metal tab inside the strike plate opening.
Sometimes, things do not go perfectly. What if the lever door handles feel stiff? This usually happens because the mounting screws are too tight, warping the mechanism. Loosen the screws half a turn and test the handle again.
Another common issue is a misaligned latch. If the door handle lever turns but the latch does not retract fully, the spindle may not be centered in the latch mechanism. You might need to uninstall the interior door lever handles and reseat the spindle. Also, ensure the latch faceplate is flush; a protruding plate can cause the door to bind against the frame.
To keep your interior door lever handles looking and working like new, what maintenance is required? Periodically check the mounting screws. The motion of using a door handle lever can loosen screws over time. A quick tightening every few months prevents the handle from becoming wobbly.
Clean the finish of your lever door handles with a soft, damp cloth. Avoid harsh chemicals or abrasive scrubbers, as these can damage the protective coating on the metal. Regular cleaning prevents oils from your hands from tarnishing the finish of your door handle lever.
When you are ready to purchase new hardware, where should you look? Quality matters. Cheap levers often have weak internal springs that cause the handle to sag over time. You want lever door handles that feel solid and offer smooth mechanical action.

Generally, it takes about 15 to 30 minutes to install a single door handle lever if you are replacing existing hardware. If you need to drill new holes, it may take closer to an hour.
While physically possible, it is not recommended. Interior door lever handles usually lack the security features, such as deadlocking plungers and weatherproofing, required for exterior entryways.
No, you usually do not need a professional. Installing lever door handles is a very common DIY project. As long as you have a screwdriver and can follow basic instructions, you can install a door handle lever yourself.
Stand on the outside of the door (the side you use a key on or enter into). If the hinges are on the left, it is a left-handed door. However, many modern interior door lever handles are reversible, meaning they can be installed on either side.
Sagging usually occurs because the internal springs are weak or the handle was not installed horizontally. Ensure the mounting screws are tight and the square spindle is properly seated. Higher quality lever door handles typically have stronger springs to prevent this.
Yes, in most cases. Standard door knobs and lever door handles fit into the same 2-1/8 inch bore hole. You simply swap the hardware.
This means the backset is incorrect. You need to adjust the latch on your door handle lever. Most latches can switch between 2-3/8" and 2-3/4" lengths.
