How to Do Your Own Lock Repair

1. Door Handle or Knob Lock
As time passes, door knobs and handles could become loose. This could result in the knob or handle becoming jiggly that is difficult for you to open. Door knobs that are loose aren't just annoying but they could compromise your home's security, making it essential to identify and resolve the issue as quickly as possible. Fortunately, a broken doorknob or handle is relatively simple to fix. Depending on the type of lock you have installed on your door, there are a variety of ways to fix this. Some systems have exposed mounting screws that are accessible, while others have a backplate that hides the screws that hold the lock together. If your door is the second type, this process could be more complex.
The majority of interior doorknobs are designed to slide over a cylindrical spindle, that is inserted into the door as a part of the latch assembly. If yours is jiggly it could be due to a tiny screw called a setscrew located inside the knob that prevents it from sliding across spindle. You can utilize an flashlight to locate the set screw and then tighten it with an Allen wrench. Once the screw is tightened by turning the knob, check if it feels solid.
If your knob feels like it's jiggly, then the set screw isn't placed correctly. Look for the small button that matches the spindle to ensure the screw is in the correct position. Place the knob on the spindle after pressing the button using the screwdriver with a flat head. As you do this the knob should click into place which indicates that it has been rightly positioned on the spindle.
After you've confirmed that the set screw has been properly positioned and tightened it again to secure the knob. This should solve the issue, but if not then you might require removing the knob and examine the backplate for missing or loose screws. You'll need to replace the screws in the event of this before you can install the knob or handle. If you're not happy with this kind repair, you must seek out an expert locksmith who can offer damaged lock repair to help.

A professional locksmith will use a specialty tool to straighten the key which is designed with an angled end that fits into the groove that is recessed on the key's tip. This kind of tool isn't readily available in hardware stores, but you can find an entire kit of the correct tools online or at the locksmith shop.
A dirty or contaminated lock is also a possibility. Dust can build up over time in the lock's cylinder and cause the pins or springs to get stuck. In this case you'll be required to spray the lock with graphite spray or a lubricant made of silicone to clean it out and restore the pins to their original position.
It could also be a problem when the key has been damaged. Keys can wear down over time by repeated use, which can result in the groves wearing down or even become smoother. This can result in the key not to fit into the cylinder. It is essential to check frequently to ensure that the key is fitted correctly.
In the winter months locks can freeze, which prevents springs and pins from moving when the key is inserted. This can be a nagging issue, but it is usually quite simple to solve by warming the lock using hot water and using an oil-based lubricant to re-lubricate it. However, if the lock is damaged or frozen beyond repair, it's likely to require replacement by an expert.

Be careful not to damage the lock by cutting off any part of the broken key with the pliers.
It's possible that your lock is misaligned and this could cause the door to not latch properly. If you have an extra lock key, you may test it to ensure that the lock is operating properly. If you discover that the lock is not aligned correctly, tightening the screws around the strike plate will fix the problem and allow the lock to function normally.
Another reason your key might not be turning is that there is dirt or dust in the lock that is preventing it from moving. This issue can be fixed by using an lubricant made of silicone or graphite to coat the pins of the lock. This allows them to move up and down as normal. It is recommended to avoid oils-based products, like WD-40, because they can cause more obstructions in the future.
