Door knobs and handles may get loose as time passes, which could result in a jiggly door handle or knob that is difficult to open. Loose door knobs aren't just annoying, they could compromise your home's security, so it is crucial to solve the issue quickly. A doorknob that is loose is simple to repair. Based on the type of lock you have installed on your door, there are many solutions to fix it. Certain lock systems have easily accessible mounting screws, whereas others use backplates that hide the screws. This method is more complex in the case of an underlay that hides the screws.

The majority of interior doorknobs are designed to slide over a cylindrical spindle which is mounted in the door as part of the latch assembly. If the knob you have is jiggly it could be due to the small screw, also known as a setscrew, on the inside of the doorknob which is stopping it from sliding over the spindle. Use flashlights to locate the set screw, and use an Allen wrench to tighten it. Once the screw is tightened by turning the knob, test if it is solid.

If your knob is jiggly, it could be that the set screw isn't placed correctly. To ensure that the screw is in the correct position, look for a small, matching button on the spindle. Press the button using an screwdriver with a flat head, and then slide the knob across the spindle. The knob should click into position after you have done this, signalling that it is properly positioned on the spindle.

Once you have ensured that the set screw is positioned correctly and tightened it again to ensure that the knob is secured. This should fix the problem, but if not then you might require removing the knob and check the backplate for missing or loose screws. If this is the case, you'll need to replace these screws before you can secure the knob or handle. If you're not happy with this kind repair, you must contact a professional locksmith who offers damaged lock repair to help.

2. The key won't spin in the lock


There are a number of reasons why your key might stop turning inside the lock. One of the most frequent reasons is that the pins inside the cylinder have begun to wear out, which means they no longer have the proper shape to move the sliders, wafers or tumblers that allow the key to open the lock. In this situation, spraying the lock with lubricant made of silicone or graphite spray will coat the pins and make them move again.

If the issue is more serious and the key is been bent out of shape, you might need to have it professionally straightened. A professional locksmith can use a special tool to straighten the keys, that is designed with an angled end that fits into the groove in the tip of the key. This kind of tool is not available at hardware stores, however you can purchase a kit with the right tools online or in an establishment that sells locksmith tools.

Another possibility is that the lock has become dirty or affected. Dust can accumulate over time in the lock's cylinder and causes the springs or pins to get stuck. In this case, spray the lock with WD-40 or graphite spray to clean out the pins and restore them to their original positions.

It could also be a problem in the event that the key is damaged. In time, repeated use can cause wear and tear on the grooves on a key. This can lead to the key not fitting properly into the cylinder, therefore it's crucial to pay attention and make sure that your key is fitted correctly.

Locks can freeze in the winter months. This will prevent the pins and springs from moving when a key is placed. This can be a nagging issue however, it's usually fairly easy to solve by heating the lock with hot water and using the lubricant again to re-lubricate. However, if the lock is damaged or frozen beyond repair, it's likely to need to be replaced by a professional.

3. The Lock Isn't Turning

It can be frustrating to have locks that aren't turning or open. If this happens often you might want to think about having a locksmith come and inspect the lock to determine whether they can help. Fortunately, this isn't required as there are issues that can be easily fixed without the need for professional assistance.

The key will not rotate in the lock if it's damaged. This can happen if you've lost your key or it is broken in the lock. Instead of trying to get the key out of the lock, which could result in it being further pushed into the mechanism and increase the risk you can use needle-nosedpliers to take the key from the lock. Be careful not to scratch the lock by breaking off any piece of the damaged key with the pliers.

There could be an incorrectly aligned lock, which could cause the door to not to latch properly. If you're lucky enough to have an extra key, it could be tested in the lock to confirm that it works correctly and isn't the cause of the problem. If you find that the lock is misaligned, tightening the screws around the strike plate could solve the issue and allow the lock to work normally.

Another reason your key may not be turning is that there is dirt or dust inside the lock that is blocking it from turning. This issue can be fixed by using an lubricant made of silicone or graphite to cover the pins of the lock. This allows them to move up and down in a normal manner. It's important not to use products that contain oil such as WD-40 to solve this problem, however, because they can cause clogging problems down the road.

It is important to remember that some keys simply won't fit into all locks. If this is the case, you may require a new key created by a local hardware shop.

4. The Cylinder is rotating.

When a cylinder is rotated in a confinement space, it can cause hairpin vortices that can result in significant forces on the cylinder. These forces are proportional the radius of curvature that is dimensionless x and the confinement factor k. The simplified model presented here will predict the effect of these parameters on the torque and force on a confined rotating cylinder. The tube, head and main body of the cylinder are made of aluminium alloy.

If you're able to get your key in and turn it however the lock is still rotating there could be an issue with the cylinder. Rekeying your lock can fix this issue. You can purchase kits to do this online or in many big box stores.
