Fixing a Doorknob That Fell Off

1. Remove the Handle or Knob

You have to detach the knob or handle. This will depend on how tight the knob is and where the screws are located. Some knobs are hidden while others have exposed screws. If you have hidden screws, you have to display them by determining where the detent access hole is located. The pin is spring-activated, and can prevent the knob’s rotation because it sticks out.

After locating the pin, use a flathead screwdriver to press down on it and remove the handle. You need to remove the rose for the screws to be exposed. In this case, locate the thin slot that you’ll find between the plate and door and use the flathead screwdriver to remove the rose. This way, it will be easier for you to locate and remove the screws.

On the other hand, if you have exposed screws, it is easier to remove the knob. You need to find the set screw and loosen it with the Allen key or screwdriver. After you remove the handle, uncover the shaft, and twist the shaft’s handle to make it flush the door. If you remove the handle, or knob, the knob’s unthreaded shaft can be tightened by turning the set screw.

2. Remove the Knob Depending on How It Is Fastened

As mentioned above, how the knob is fastened determines how you will remove the knob. What you need to remember in this case are:

  • If there is a small hole, you will use a straightened paper clip or a strong wire to spring it and remove the knob.
  • In case there is a slot, you will insert a flathead screwdriver and use it to push the detent, thus releasing the knob.
  • If you have a hex-head screw, use an Allen Wrench to turn it counterclockwise until the knob is free.

3. Remove the Base

Removing the base comes next after the handle or knob is separated from the spindle shaft. Use the flathead screwdriver to loosen the ring holding the base. Be extra careful when doing this to avoid damaging the backing plate. If the backing plate is damaged, it could be destructive to the whole set, resulting in the need to buy a new lockset. Therefore, ensure that you do it right to avoid losses.

4. Tighten the Screws

If the ring is removed, you will see the screws you need. These screws run through the door from the inside to the outside backing plate. It holds everything together. Once you’ve got the screws, make sure to check for damage. Fixing the doorknob with damaged screws is in vain since the doorknob may fall off after a short time.

After verifying that you have all the necessary screws, secure the backing plates to the doorknob and tighten each one individually. Do this thoroughly to avoid having the plates fall off in case you bang the door.

5. Restore the Base and Set the Knob in Place

The only step remaining is restoring the base and putting the handle back in its position. Snap the backing plate’s ring onto the base and place the handle on the spindle shaft.

Once the handle is placed on the spindle shaft, turn it to ensure that it is in-line with the holes and detents, then click it into place. Install the rose if it has been removed or is not part the knob assembly. Start with the outside of the door.

Use a head screwdriver to fasten all the screws to ensure that they are tightened. Additionally, slide the knob and turn it until the detent clicks into the alignment, and has access to the slot. You should also use the Allen wrench to tighten the recessed screws.

Extra Tip

Ensure you don’t over tighten the screws that can bind the bolt and knob action, and this is why you need to use a flathead screwdriver or the Phillips screwdriver as opposed to a power screwdriver or a drill.

You need to alternate between the screws to ensure even pressure, and as you tighten, you need to snug them down.

Conclusion

Your doorknob is one of the items in your home or office that may malfunction and fall off. Although this may cause several inconveniences, it should not be a source of tension. You can fix the problem within a short time, without having to contact a professional. You can accomplish this quickly with the right tools. Use the information discussed to guide you in what you need to get your door functioning again.
