There are often instances where we are stuck with a broken lock or locked out of the room. Such situations could be frustrating and we end up losing our patience while dealing with the door hardware. However, changing or replacing a doorknob is a fairly simple task. A little bit of Do-It-Yourself (DIY) experience with a door hardware lock is all you need to do a good job. A novice’s expertise in handling doorknobs is sufficient to work out the task of changing or replacing door knobs. 

The process is the same for replacing an old and worn-out doorknob or giving a new look to your home. In this article, we will provide you with a detailed step-by-step guide on how to change or replace a doorknob. By following these given steps, you will succeed in the task of replacing your doorknobs in no time.

Step 1: Know your knob

Before you go forward with changing your doorknob, study your existing door hardware lock. Understand its pattern. Make efforts to understand what procedure should you implement to remove the doorknob. 

Step 2: Collect the required tools 

As a second step, make sure you prepare a list of tools or materials that you need to replace or change your doorknob. Post that, follow the list, and collect the tools and materials. For starters, you will need:

  • Doorknob
  • Screwdriver
  • Drill
  • Screws
  • Chisel (If your doorknob has a mortise for the latch plate)

Now that you have all the required tools and materials on hand, let’s proceed with the next step.

Step 3: Dismantle the old doorknob

To start dismantling your existing doorknob, you have to begin by identifying the screws that hold them in place. You have to remove the screws holding one side of the doorknob. If any screws are present on the other side, remove them as well. Remove the doorknobs present on either side and keep the screws in a safe place nearby. 

Usually, the doorknobs are connected with a square steel peg. This steel peg slides into a square hole in the latch. When the door knobs are removed, this square steel peg also comes off. 

Step 4: Remove the latch mechanism

Now that you have removed the old doorknob, you have to remove the latch mechanism that is attached to the knob. Usually, it is the part in the doorknob which extends to the door frame. It keeps the door closed. Sometimes, they can be removed with some force. 

If they are attached through screws, find the screws that hold them together and use your screwdriver to unscrew them. After successfully unscrewing them, you can pull the latch mechanism out of the door. This is followed by removing the strike plate attached to the door. 

Step 5: Find the right doorknob

Before you move forward with finding a new doorknob, find the number on your latch. It should be either 2-3/4 or 2-3/8 inches. This number refers to the backset of the doorknob. It is the distance from the edge of the door to the center of the doorknob hole. 

The doorknob that you choose should meet the backset value of your existing doorknob. If you are interested in buying a doorknob with a lock, decide whether you want the lock inside or outside. You cannot interchange the positions of inner and outer doorknobs.

Step 6: Start with the latch

Insert the new latch mechanism into the door’s hole. However, you have to ensure that it is positioned precisely and the bolt of the latch is extended fully through the door. After inserting the latch, secure them with screws. Also, the position should match the direction of your door’s swing.

Step 7: Add the knobs

Check the two knobs and choose the one that has a rod essential to connect with the latch and the other knob first. Slide the doorknob’s rod into the latch. Confirm that they are positioned over the hole and fasten it with screws. 

Now, pick the second knob and interlock it with the rod mechanism of the first doorknob. Tighten them with screws. Now, both the doorknobs are added. Finally, insert the strike plate into the doorframe.

Step 8: Test the new doorknob

After installing the new doorknob, test it repeatedly to make sure it is working correctly. Turn the doorknob to ensure that it is properly connected and that it turns the latch mechanism. 

Best Practices

  • When you purchase a new doorknob, make sure you choose one that fits the right size frame for your door. Though most doorknobs are designed to fit standard doors, there are some variations in size that will affect your installation.
  • It can be a tricky process if there is a mortise for the latch plate in the door. You will need to use a chisel to create a recess for the new latch plate. Be patient at that time.
  • Always use a lubricant such as WD-40 to help loosen the screws if you are having trouble removing the old doorknob. 
  • When installing the new doorknob, make sure you tighten the screws evenly. When you tighten unevenly, it can cause the doorknob to become misaligned and difficult to turn.
