What You Need to Do Before You Start

Replacing a door handle takes about 30 minutes and requires only a screwdriver and the new handle itself. You do not need to remove the door from its hinges. The old handle unscrews from the inside of the door, and the new one screws in the same way — it is the simplest door repair most people can do alone.

Before you buy a replacement, measure the distance between the two screw holes on your current handle. This measurement, called the backset, is usually 2.375 inches or 2.75 inches. Write down which one yours is. You also need to know whether your door is a standard interior door or an exterior door with a deadbolt, because the hole pattern differs. Take a photo of your current handle from the side so you can match the style when you shop.

Gather your tools: a Phillips or flathead screwdriver (check which your current handle uses), the new handle, and a small flashlight if the space is dim. That is all you need. If your new handle came with installation instructions, read them first — some brands have slightly different steps.

Key Takeaways

  • The backset (distance between screw holes) must match your old handle, usually 2.375 or 2.75 inches, or the new handle will not fit.
  • Remove the interior side of the old handle by unscrewing the two screws that hold the handle assembly to the door.
  • Slide the handle straight out and note which way the spindle (the metal rod connecting both sides) faces so you install the new one the same way.
  • Insert the new handle's spindle through the hole, align the screw holes, and tighten both screws firmly but not so hard you crack the handle.

Remove the Interior Handle

Look at the inside of your door handle. You will see two screws holding the handle assembly to the door — one above the spindle and one below it. These screws go through the handle and into the door itself. Use your screwdriver to remove both screws completely. Keep them in a small cup so you do not lose them.

Once both screws are out, the handle assembly will slide straight toward you. Pull it gently but firmly. The spindle (the metal rod that connects the interior handle to the exterior one) will come with it. Set the old handle aside. Look at the hole in the door where the spindle was — you will see a small metal rod sticking through from the other side. This is the spindle from the exterior handle, and it stays in place.

Check the Spindle and Prepare the New Handle

Before you install the new handle, look at the spindle sticking through the door hole. It should be smooth and not bent or damaged. If it is bent, you will need to replace it separately — most hardware stores sell spindle kits for $8 to $15. For now, assume it is fine and move forward.

Unpack your new handle and lay out both pieces (interior and exterior) on a clean surface. Look at the spindle slot on the interior handle — this is the rectangular opening where the spindle slides in. The spindle must slide in smoothly. If your new handle came with a spindle, use that one instead of the old one. If it did not, you will reuse the old spindle.

Install the New Interior Handle

Slide the spindle through the spindle slot on your new interior handle. The spindle should move freely and not bind. Now hold the handle up to the door and align the two screw holes with the holes in the door. The handle should sit flat against the door with no gaps.

Insert both screws by hand first, turning them a few times to make sure they are threading correctly. If a screw feels stuck or hard to turn, stop and check that the hole is aligned — forcing a screw can strip the threads. Once both screws are hand-tight, use your screwdriver to tighten them firmly. They should be snug enough that the handle does not wiggle, but not so tight that you hear cracking sounds or feel the handle flex. If you overtighten, you can crack the handle or strip the screw holes.

Test the Handle and Install the Exterior Side

Turn the interior handle. It should turn smoothly and the latch should retract (pull back into the door). If it does not move or feels stiff, stop and check that the spindle is fully inserted and not twisted. Once the interior handle works, you can install the exterior handle.

The exterior handle usually comes pre-assembled. Slide it onto the spindle from outside the door, making sure it aligns with the interior handle. Most exterior handles have two screw holes that line up with the same holes you just used. Insert and tighten those screws the same way — hand-tight first, then snug with the screwdriver. Test both handles again. The interior and exterior should turn together smoothly, and the latch should retract when you turn either handle.

Common Mistakes to Avoid

The most common error is buying a handle with the wrong backset. If the screw holes do not line up with the holes in your door, the handle will not fit no matter how hard you try. Always measure before you buy. The second mistake is overtightening the screws, which can crack plastic handles or strip the holes in the door. Tighten until snug, then stop.

A third mistake is installing the spindle backward or upside down. The spindle should slide smoothly through the slot in the handle. If it binds or feels wrong, remove it and check the orientation. Finally, do not force a screw that feels stuck. If a screw will not turn easily, the hole may be misaligned or the screw may be the wrong size. Back it out and try again.

When to Call Someone Else

If the spindle is bent or broken, you can replace it with a spindle kit from any hardware store — they cost $8 to $15 and install the same way. If the screw holes in the door are stripped (the screws spin but do not tighten), you can move the handle slightly and drill new holes, or use larger screws. If the door itself is damaged or the latch does not work after installation, the problem is likely not the handle.

If you are not comfortable using a screwdriver or the handle does not work after you install it, a handyperson or locksmith can install it for $50 to $100. For most people, though, this is a straightforward 30-minute job that saves money and builds confidence for the next repair.

Frequently Asked Questions

Do I need to remove the door from its hinges?

No. The handle screws are on the inside face of the door, so you can replace it while the door hangs in place. You do not need to touch the hinges.

What if the new handle does not fit the hole in the door?

The backset (screw hole spacing) does not match. Measure the distance between the holes on your old handle and buy a new one with the same measurement. Most handles are 2.375 or 2.75 inches — check both before you shop.

Can I replace an interior handle with an exterior handle or vice versa?

No. Exterior handles have a deadbolt mechanism and a different hole pattern. Interior handles are simpler and will not fit an exterior door frame. Buy the correct type for your door.

The handle turns but the latch does not move. What is wrong?

The spindle is likely not fully inserted or is twisted. Remove the interior handle, check that the spindle slides freely through the slot, and reinstall it. If the latch still does not move, the spindle may be bent and need replacement.

How tight should the screws be?

Tight enough that the handle does not wiggle or move when you push on it, but not so tight that you hear cracking or feel the handle flex. If you can turn the screw with one finger, it is too loose. If you need both hands or a lot of force, you are too tight.
