How to Fix a Broken Door Knob

Why Did My Door Knob Break?

Before we get into how to fix a broken door knob, let’s first talk about why they break in the first place. There are a few different reasons that door knobs can break, including:

Wear and Tear: 

As door knobs are used frequently, they can become loose over time and eventually break. Therefore, it’s important to check doorknobs regularly for looseness and tighten them if necessary to prevent breakage.

Poor Installation:

If your door knob is not installed correctly, it could break. This is usually due to screws that are too long or not properly positioned. Installation problems can also cause door knobs to become loose over time.

Poor Quality:

If you’re fed up with flimsy door knobs that keep breaking, it might be time to invest in a sturdier product. Cheap door knobs can also be more difficult to operate, making them a pain to use on a daily basis.


If a door knob is hit hard enough, it can break. This is more likely to happen with lower-quality door knobs that are made with less durable materials. It can also happen if the door knob is loose and not tightened properly.

Accidental Damage:

Door knobs are susceptible to breakage from accidental damage, like being hit with a heavy object or dropped. Lower-quality door knobs are more likely to sustain accidental damage, so be sure to choose a durable option if you’re worried about this.

Temperature Changes:

Sudden temperature changes can break door knobs, especially if they’re made with materials sensitive to temperature changes. This is more likely to happen in areas with extreme temperatures, like a garage that’s not climate-controlled.

Faulty Manufacturing:

Sometimes, door knobs break because they were made with a manufacturing defect. This is relatively rare, but it can happen. If you suspect that your doorknob is defective, contact the manufacturer to discuss your options.

Things You’ll Need

  • A new door knob
  • A screwdriver

15 Ways How to Fix a Broken Door Knob:

1. Remove the Broken Door Knob

The first step is to remove the broken door knob. To do this, first, remove the screws that hold the door knob in place. If you can’t find the screws, they may be hidden under a small plate on the door knob. Once the screws are removed, the doorknob should come off easily.

2. Clean Up the Area

Once the door knob is removed, take a moment to clean up the area. Remove any debris or dirt that may be present. This will help to ensure that the new door knob is properly installed. Next, use a soft cloth to wipe down the area and remove any dirt or debris. If the area is particularly dirty, you may need to use a mild cleaner and a brush to remove all the dirt.

3. Inspect the Door Knob for Damage

Once the area is clean, inspect the doorknob for damage. If the door knob is cracked or damaged, it will need to be replaced. If the damage is minor, however, you may be able to repair it. If the doorknob is made of metal, you can try using a soldering iron to repair any cracks or chips. If the doorknob is made of plastic, you can use a strong adhesive to repair any cracks or chips.

4. Replace the Door Knob

If the door knob is damaged beyond repair, you’ll need to replace it. To do this, purchase a new door knob that is the same size and style as the old one. Once you have the new doorknob, hold it up to the door to make sure it is the correct size. If it is, proceed to the next step. If it is not, return it and purchase the correct size.

5. Install the New Door Knob

Once you have the new door knob, it’s time to install it. Begin by holding the new door knob up to the door. If the new door knob is the same size as the old one, the holes should line up perfectly. If they don’t, you may need to drill new holes. Once the holes are lined up, insert the screws and tighten them until the door knob is snug.

6. Add the Latch

If your door knob has a latch, it will need to be installed before you can use the doorknob. To do this, first, insert the latch into the hole on the door. Once the latch is in place, use a screwdriver to secure it. Be sure to tighten the screw until the latch is snug. Otherwise, it may become loose over time.

7. Add the Strike Plate

If your door knob has a strike plate, it will need to be installed before you can use the doorknob. To do this, first, insert the strike plate into the hole on the door frame. Once the strike plate is in place, use a screwdriver to secure it. Be sure to tighten the screw until the strike plate is snug. Otherwise, it may become loose over time.

8. Test the Door Knob

Once the door knob is installed, it’s time to test it. Open and close the door a few times to make sure the door knob is working properly. If it is, you’re all done! If not, check to ensure all the screws are tight and the latch and strike plate are properly installed.

9. Adjust the Door Knob

If the door knob is not working properly, you may need to adjust it. To do this, unscrew the doorknob and remove it from the door. Then, please take a look at the connecting hardware and make sure that it is tightened properly. If it is not, tighten it with a screwdriver. Finally, reattach the doorknob and test it to see if it is working properly.

The most common type is the screw-in door knob, which is attached to the door with two screws. Another type is the snap-on door knob, which is attached with a single screw.

Frequently Asked Questions

Can a Door Knob Be Fixed?

Door knobs can be tricky to operate because they often need tight tolerances in order to work properly. If the screws that hold the knob on have become loose, this could cause the knob to move around or even come off entirely. In addition, if there is moisture or chemicals nearby (such as paint), these might also contribute to factors that make fixing your door difficult.

A professional will be able to inspect the situation and recommend any necessary repairs before proceeding further. Sometimes it’s possible just to replace certain parts of the screw mechanism with better quality ones, which will solve many issues on its own without requiring too much additional effort from your end.

Are Doorknobs Universal?

Unique doorknobs are certainly a thing of the past and for good reason. They’re often outdated and difficult to use, which can lead to frustrating experiences for both you and your guests.

These types of knobs require no keypad entry; simply press the button on the handle to open the door.

This technology is not only more user-friendly but also more secure since there is less opportunity for theft or misuse. Additionally, these features make it easier than ever before for people with disabilities or limited mobility access to enter their homes safely and easily.

What Are the Different Types of Door Knobs?

There are many types of door knobs, but the three most common are:

  1. Traditional door knobs – These are the most common type and are usually made from metal or plastic. They have a round or octagonal shape and are used to open and close doors manually.
  2. Push-button style door knobs – These are often found in homes with automatic doors. They have a round or square shape and a built-in button that you push to open the door.
  3. Electronic door handles – These are becoming more popular because they’re more secure and easier to use than traditional door knobs. They typically have a touch screen display that you use to open the door.

What Causes Door Hinges to Break?

Door hinges are susceptible to a number of common problems, including wear and tear, rusting screws, squeaks, and loose connectors. The most common cause of door hinges breaking is the latter – loose connectors that can become disconnected from the hinge or jamming in between joints. This can lead to loosening or even catastrophic failure of the hinge.

There are several ways to prevent this from happening: Regularly lubricate all moving parts with a quality lubricant; use weatherproof screws that resist corrosion; install properly sized washers on all hardware connections; check for signs of joint stress (e.g., squeaks), and tighten as necessary; replace worn out parts promptly.
