Fix a loose doorknob
Loose doorknobs are a common problem on commonly used doors around the home. Sometimes the doorknob or lever loosens so that it rotates on its spindle, while the lock ring and faceplate of the locket sometimes loosen and pull away from the surface of the door. How you fix the problem will depend on the design of your doorknob or lever and how it is attached to the spindle and door.

When the doorknob is loose on its spindle
If the doorknob turns loosely on its spindle, the cause is a set screw that has come loose and lost its grip on the handle spindle. This is almost always a problem that occurs with older doorknobs because new models have knobs attached to the spindles with a different mechanical system.
On these older doorknobs, find the collar on the doorknob and identify the set screw that screws into the collar. This screw can be a pan head screw, a Phillips head screw, or sometimes a recessed hex head screw. Use a suitable screwdriver or wrench to tighten this screw and secure the handle of the door handle to the spindle.
If the locking screw is lost, take the doorknob to the hardware store to purchase a replacement screw.

Loose front panel with exposed mounting screws
On many newer, less expensive locksets, the faceplate - the round plate that fits the door surface itself - has two exposed screws that can loosen over time, causing the doorknob mechanism to wobble loosely.
When this occurs it is easy to tighten these screws to reattach the door.
With lever handles, you can almost always have easy access to the mounting screws. With round doorknobs, you may have to remove the knob to make the screws for the front panel accessible to your screwdriver. The door knob can be fastened with a locking screw (see picture above) or with a locking button or slot.
Tighten the front panel with a screwdriver. If the screws have completely loosened from the mounting threads on the opposite side of the door, you may need to start by hand before using the screwdriver.
Tip: Be careful not to overtighten the mounting plate. It is possible to tighten enough that the internal mechanism binds together, causing your lockset to not work at all.

Loose front panel with hidden fastening screws
On a newer, high-end lock, the mounting screws that hold the lock plate to the door may be hidden under an outer cover.
1. To get to these fastening screws, the doorknob / lever is first pressed by pressing a spring-loaded Rested , known as a Rested , solved and the button / handle slid off the spindle. There are three common ways to access and depress the hidden latch that secures the handle:
- Small round hole
This type is often found at Door handles with levers . To squeeze the latch, use the end of a metal paper clip or the tip of an awl, insert it into the opening, and push the latch down as you twist and remove the door handle shaft from the spindle.
- Slot hole
This type is usually found on round doorknob hardware sets. To squeeze the lock, use a small flat-blade screwdriver through the slot to push and release the lock as you twist and remove the doorknob from the spindle.
Button-like notches are often found on less expensive round doorknob hardware sets. You have a button that is flush with the surface of the doorknob. Use an awl or the tip of a small flat-bladed screwdriver to depress the button while turning the doorknob and removing it from the spindle.
2. Now lift off the front panel - a decorative panel that covers the fastening ring of the lock frame. Sometimes this is a simple friction ring that can be pulled off the spindle. there may be a small notch in the space designed for this purpose. On other models, the front panel is threaded in and removed by loosening it counterclockwise.
3. Now tighten the long screws with which the fastening ring of the lock is attached to the door. These screws generally pass through the door and are attached to the lock plate on the opposite side. Tighten firmly, but don't overtighten, as this can sometimes cause the internal locking mechanism to snap into place.
4. Once the lockset is tightened, reinstall the decorative faceplate and doorknob.
