How To Replace An Internal Door Knob

How To Replace An Internal Door Knob

Whether they're too stiff, loose or just too outdated to be used anymore and you have bought new doors,interior doorknobs are something you can easily replace yourself.

With a few basic tools and the steps outlined below, you can start removing the screws, replacing the plates, and adjusting the openings to fit your fantastic new doorknob which incidentally we hope you are going to purchase from More4Doors!

What You Need:

  • Door Knobs
  • Strikeplate
  • Mortice Latch
  • Screwdriver
  • Screws


Step 1

Obviously like we just said, purchase your replacement door knobs from More4Doors. Besides the style, look for something solid that will hold up to regular use and last a long time. Also, consider whether this will go on a bedroom, bathroom or closet. Should it have a privacy lock? Does it need to be fitted with a door lock or latch? Do I need a bathroom turn and release mechanism? Do I need a keyhole? 

Step 2

Remove the screws on the latch face plate. Twist counter clockwise to remove.

Step 3

Remove the screws on the knob plate. The door knobs will then become loose, so be prepared for both sides to fall.

Step 4

Pull the doorknobs off both sides.

Step 5

Push the faceplate and mortice latch out through the opening in the side of the door.

Step 6

Loosen the two screws on the latch strike plates that will be attached to the door frame and remove the strike plate.

Step 7

Size up the new strike plate and mortice latch mechanism with the holes in your door and door latch barrel length.

Step 8

Use a hammer and chisel to adjust the openings in the door and door jamb, if necessary.

Step 9

Push the new mortice latch mechanism and face plate into the door. Be sure the latch faces the way the door will close, so the slanted side will meet the strike plate. Pushing with your hands should work. Otherwise, you may have to drill the hole a bit larger. Alternatively, you can place a block of wood against the face plate and tap on the block of wood with a hammer.

Step 10

Screw down the latch mechanism on to the door, making sure it is as level and secure as possible.

Step 11

Insert the knobs into the door so that the square spindle provided with the knobs fits through the square opening in the mortice latch and the screw holes align with the threaded cylinders on the other side.

Step 12

Insert and tighten the screws provided with the door knobs thus ensuring the knob is fitted tightly to the door.

Step 13

Install and fit the new strike plates on to the face of the mortice latch and also on the door frame.

Step 14

Check that everything fits and closes properly, and make any necessary adjustments if required.

Step 15

Relax and enjoy your new door knobs which will last for years if maintained correctly and not abused.
