How to Do Your Own Lock Repair
When your locks become faulty, you can try to fix them yourself or hire an expert locksmith. However, repair of locks can be tricky and if you don't follow the correct procedure, it could result in further damage.

1. Door Handle or Knob Lock
Over time, door knobs and handles may become loose. This can lead to an unbalanced knob or handle that is difficult to open. Loose door knobs aren't just annoying, they can also compromise your building's security, so it is essential to identify and solve the issue quickly. Fortunately, a loose doorknob or handle is fairly simple to repair. Based on the type of lock you have installed on your door, there are several ways to fix this. Some lock systems have visible mounting screws that are easy to access, whereas others have a backplate that obscures the screws holding it together. This method is more complex in the case of a backplate that hides the screws.
Most interior doorknobs come with a small screw known as an setscrew located on the inside of the knob, which prevents it from sliding over the spindle. This is a part of the latch assembly. If yours is not jiggly, it could be due to a small screw called a setscrew located on the inside of the knob that prevents it from sliding across spindle. Use flashlights to locate the screw and use an Allen wrench to tighten it. After it's tightened, test the knob and check if it no longer appears to be like it's jiggly.
If the knob is still uneven, it could be that the set screw isn't positioned correctly. Find the small button that matches the spindle to make sure the screw is in the right position. Place the knob on the spindle after pressing the button using the flathead screwdriver. The knob should move into the proper position after you have done this, signalling that it is positioned correctly on the spindle.
After ensuring the set screw is positioned properly and tighten it once more to ensure that the knob or handle is in place. This should solve the issue, but if not it is, you will need to remove the knob and check the backplate for loose or missing screws. It is necessary to replace the screws in the event of this before you can replace the knob or handle. If you're not comfortable with this type repair, call an expert who is skilled in repairing damaged locks.

There are many reasons that your key may stop turning inside the lock. One of the most common reasons is that the pins in the cylinder are beginning to wear out and, consequently, they no longer have the proper shape to move the sliders, wafers, or tumblers that allow the key to open the lock. In this instance, spraying the lock with lubricant based on silicone or graphite spray can help coat the pins and make them move again.
If the issue is more severe and the key is bent out of shape, it may be necessary to have it straightened professionally. A professional locksmith will use an exclusive tool that has an edge that is curved to fit into the groove that runs along the edge of the key. This type of tool isn't available at hardware stores, but you can find a kit that includes the proper tools online or at an establishment that sells locksmith tools.
Another possibility is that the lock is dirty or damaged. The accumulation of dust over time can cause problems within the lock's cylinder, and cause the springs or pins to become stuck. In this situation spray the lock with WD-40 or graphite spray to remove the pins, and then return them to their original places.
It may also be a problem if the key has been damaged. Over time, the repeated use can cause wear and tear on the grooves of a key. This could lead to the key not fitting properly into the cylinder, so it is important to be aware and regularly check whether your key fits properly.
In colder weather locks can freeze which prevents the pins and springs from moving when the key is put in. This can be a nagging issue, but it is usually quite simple to solve by warming up the lock with hot water and using an oil-based lubricant to re-lubricate it. If the lock is damaged beyond repair, or has frozen it must be replaced.
