A door knob is an important part of your door, but after awhile, it can wear down or even break and require a replacement. Luckily, replacing your door knob is very simple and only requires a couple of tools. Even though there are several types of door knobs, our door repair experts will explain how to install a traditional round knob.
What you’ll need to install a door knob:
- Flat key
Removing the Old Knob
- First, locate the screws that hold the door knob in place.
- Next, use your screwdriver to remove the screws (including ones on the cover plate, if present).
- If there are no screws on the cover plate, look for a small slot on the side of the knob.
- Use a standard flat door knob key to press on the piece of metal inside the slot. This should pop both sides of the knob loose.
- After that, remove the knobs, then remove the latch.
- Next, unscrew the screws that hold the strike plate in place and remove.
Installing the New Knob
- Before you purchase a new knob, measure the distance from the middle of the door hole to the edge of the door. (Typically, this measurement will be 2 3/8 or 2 3/4 inches.) Make sure your new knob fits those measurements.
- Also keep in mind which side of the door you want your lock on, since door knobs aren’t reversible.
- First, slide the latch into the side hole.
- Next, locate the side of the knob that has a square peg in the center.
- Insert this half into the door first, making sure the peg is through the latch.
- Line up the other half of the door knob and press both halves together.
- After that, locate the screw holes and insert your new screws. Tighten down with your screwdriver.
- Attach your new strike plate and screw in place.
