In daily life, the anti-theft door in our home often uses a period of time to find some abnormal noise, especially when opening the door and screwing the key. In fact, this is because the mechanical structure inside the door lock is rusted. If the door lock is unusually loud, or the key cannot be turned on, try not to use a lot of effort to unscrew it. Because it is very easy to twist the key, the key can not be removed in the keyhole. For rusty door locks, we might as well try these few tricks.
The main reason for the rust of the door lock is that the internal structure of the door lock is basically a steel structure and a copper structure. In the air, the moisture in the air will invade the door lock through the keyhole all the time, or directly eroded the inside of the door. Rusting is inevitable for this.
In everyday life, door lock rust is a relatively common situation. But when we open the door, we should try to avoid turning the key hard. In some cases, due to the long-term use of the security door, the door body has physically sunk, and the circlips will become tighter. If we turn the key hard, it is easy to break the key.
In this regard, we should first determine the exact cause of the door lock abnormal sound or the key is difficult to screw. In addition to the above reasons for sinking, the more common reasons for daily use are generally the lack of oil in the lock, causing moisture in the air to invade the door lock and rust. We need some lubricant to help us open the door lock. Commonly available lubricants include, sewing machine lubricants, kerosene, gear oils, and the like. However, it is not recommended that you choose cooking oil. On the one hand, the lubricity of edible oil cannot be compared with professional lubricating oil. Secondly, edible oil is also prone to bacteria and mold, which makes locking lock more difficult to screw.
On the other hand, if there is a pencil in the house, we should better choose the pencil core powder to lubricate the keyhole as a lubricant. Because the pencil core powder is less sticky than the liquid lubricant, and the pencil lead powder can be attached directly to the door lock. However, pencil powder is not easy to put into the keyhole compared to lubricating oil. For this we can sprinkle the pencil powder on the key and insert it into the door lock.
In the daily life, door lock rust is more common, we just need not force the key to ensure that the key will not break in the keyhole to solve the problem of door lock rust. At the same time, the problem of rusting with these small door locks can be solved easily!
