Knobs that are loose in the door are not only annoying but they can also compromise your building's security, which is why it's important to find and fix the problem quickly. A doorknob that is loose can be simple to fix. There are a few different ways to do this, dependent on the type of lock your door comes with. Certain lock systems have easily accessible mounting screws, while others have backplates that conceal the screws. This method is more difficult if your door uses a backplate that hides the screws. Most interior doorknobs have a small screw called a setscrew on the inside of the knob that prevents it from sliding over the spindle. This is a part of the latch assembly. If yours is jiggly, it could be due to a small screw known as a set screw located inside the knob, which prevents it from sliding across spindle. You can utilize a flashlight to locate the set screw, then tighten it with an Allen wrench. After it's tightened, try turning the knob to see if it no longer feels jiggly. If the knob is still jiggly, it's possible that the set screw isn't placed correctly. Find an oblique button that is positioned to match the spindle to make sure the screw is in the correct position. Depress the button with an screwdriver with a flat head, and then slide the knob across the spindle. The knob should click into place as you do this, which indicates that it is properly positioned on the spindle. Once you have ensured that the set screw has been positioned correctly, tighten it once more to ensure that the knob is secured. This should resolve the issue however, if it doesn't it is, you will require removing the knob and examine the backplate for loose or missing screws. If this is the case, you'll require replacing these screws before re-securing the knob or handle. If you aren't comfortable with this kind repair, you must seek out a professional locksmith who offers repairs for damaged locks. 2. Key Won't Turn in the Lock There are a variety of reasons that your key may stop turning in the lock. One of the most common reasons is that the pins within the cylinder are beginning to wear down and do not have the right shape to move the wafers, sliders, or tumblers that allow the key to open the lock. In this case spraying the lock with lubricant based on silicone or graphite spray will coat the pins to allow them to move again. If the issue is more serious and the key has been bent, you may have to have it straightened by an expert. A professional locksmith will use a specialty tool to straighten the keys, that is designed with a curved end to fit into the groove that is recessed on the tip of the key. This kind of tool is not able to be found in hardware stores. However you can buy an entire set of necessary tools on the internet or from locksmiths. A dirty or contaminated lock is also a possibility. Dust can build up over time in the lock cylinder and cause the pins or springs to get stuck. In this case, spray the lock with WD-40 or graphite spray to remove the pins, and then return them to their original position. If the key itself is damaged, it could also be a problem. Keys are worn down over time through repeated use, which will cause the groves to wear down or even become smoother. This could lead to the key not fitting properly into the cylinder, therefore it's important to pay attention and regularly check that your key fits correctly. Locks can freeze up during the winter months. This will prevent the pins and springs from moving when a key is placed. This is a problem that can be frustrating however, it's usually relatively simple to fix by warming up the lock using hot water and using the lubricant again to re-lubricate. If the lock is damaged beyond repair or has froze the lock, it will have to be replaced. 3. The Lock Isn't Turning It can be frustrating to have locks that aren't turning or open. If it occurs frequently, you may want to contact locksmiths to take a look and see if they can assist. This is not always necessary since some issues can be solved by yourself. Sometimes, the key won't turn in a lock because it's damaged. It could happen when you've lost your key, or if it's broken inside the lock. Instead of trying to get the key out of the lock which could result in it being forced deeper into the mechanism and increase the risk using needle-nosed pliers, you should remove the key from the lock. Be careful not to damage the lock by cutting off any piece of the damaged key using the pliers. It's also possible that your lock isn't aligned properly and this could cause the door to not latch properly. If you have an additional lock key, you may test it to ensure that the lock is operating correctly. If you find that the lock is misaligned by tightening the screws around the strike plate could solve the issue and allow the lock to work normally. A lock might not rotate due to dust or dirt. Using an graphite spray or silicone-based lubricant could solve this problem by coating the pins within the lock to allow them to move up and down as normal. Avoid using oils-based products, such as WD-40, because they can cause more clogging in the future. It's also worth noting that there are certain kinds of keys that aren't able to fit into all locks. If yours is one of them, it might be time to get a replacement key made at an area hardware store, so that it can be used inside the lock. 4. The Cylinder is Rotating Hairpin vortices can form when a cylinder is rotated within a confinement. These vortices may exert significant forces on the cylinder that is rotating. These forces are proportional to the curvature radius that is dimensionless x and the confinement factor k. The simplified model presented here predicts the effect of these parameters on the force and torque on a confined rotating cylinder. The tube, head and main body of the cylinder are made of aluminium alloy. If you're able insert your key inside and turn it but the lock is still rotating there could be an issue with the cylinder itself. Rekeying the lock can fix this problem. You can buy kits for this purpose online or in a lot of big box stores.
