How do you check if you need to replace cylinders?

To check whether a cylinder lock needs to be replaced, look for various signs of wear or damage. Keys that are stuck or difficult to turn are often an indication that the cylinder is no longer working properly. If the key no longer slides smoothly into the lock or you feel resistance when turning, it may be worn. Also, if you see damage to the outside of the cylinders, such as bending or cracking, it is time to replace it. It is important to address a faulty lock quickly because it can reduce the security of your home or property. Regular maintenance, such as lubricating the lock with graphite powder, can extend its life and prevent you from having to replace the cylinder.
