Tools and Materials Needed

  • New door knob
  • Screwdriver
  • Drill
  • Hole saw bit
  • Tape measure
  • Pencil

Steps to follow

Step 1: Remove the old door knob

To begin, remove the old door knob by unscrewing the screws that attach it to the door. You may need to use a screwdriver or drill to do this, depending on the type of screws used. Once the screws are removed, pull the knob off the door.

Step 2: Measure the door

Use a tape measure to determine the thickness of the door. Most door knobs are designed to fit doors that are between 1 3/8 inches and 1 3/4 inches thick. Make sure the new door knob you purchase is compatible with the thickness of your door.

Step 3: Mark the door for the new door knob

Using a pencil, mark the centre of the door where the new door knob will be installed. Measure and mark the distance from the edge of the door to the centre of the hole for the latch. This distance should be either 2 3/8 inches or 2 3/4 inches, depending on the backseat of the new door knob. The backset is the distance from the edge of the door to the centre of the hole for the latch.

Step 4: Drill the hole for the new door knob

Use a drill with a hole saw bit to drill a hole in the door for the new door knob. The size of the hole saw bit should match the size of the new door knob. Start the hole saw at the centre mark you made in step 3 and drill through the door. Be sure to drill straight and at a 90-degree angle to the door.

Step 5: Install the latch

Insert the latch into the hole you drilled in the door. The latch should fit snugly in the hole. Use screws to attach the latch to the door.

Step 6: Install the new door knob

Place the new door knob on the outside of the door and insert the spindle through the latch. Align the screw holes on the inside of the door with the screw holes on the new door knob. Insert the screws and tighten them with a screwdriver or drill.

Step 7: Test the new door knob

Test the new door knob to make sure it works properly. Turn the knob to ensure that the latch moves freely and that the door opens and closes smoothly.



Congrats, you have finished the installation of the new door knob successfully! You can simply improve the appearance and functioning of your doors by following these straightforward procedures in the appropriate order.
