After a busy day, I dragged my exhausted body back home, but found that the door could not be opened. At this moment, I feel very bad. I believe that many people have encountered this situation, so what should we do when we encounter this situation? The solution to the door lock cannot be opened 1. The pull-back screw method is generally caused by external forces. So, what to do if the door lock cannot be opened in this case? This may be because of the inside. The reason why the bolt is unhooked, or the bolt is distorted, and the screws holding the bolt are detached, causing the door to jam. In this case, the best emergency treatment is to find the bolt and detach it from the door gap. Pull the screw back to position it.
2. Sharp knife unlocking method
Another method is the sharp knife unlock method. At this time, we need a knife, a sharp and thin knife. The sharper the tip, the better. First, we must hold the door from the outside of the toilet door. The shrinkable part in the middle is also called the lock shaft. Do not touch the lock shaft with the lock groove to reduce friction. Insert the lock shaft with a sharp knife to hold the lock shaft and apply force in the free direction of the lock shaft. Maybe it wo n’t open once or twice. Then, maybe it opens. 3. The last method of how to deal with the foreign object is that the door lock cannot be opened. The last method is to deal with the situation that the foreign object is stuck in the door lock and the door cannot be opened. Generally, a foreign object is stuck in the door lock, and it cannot be inserted with a key or a finger. Even if it is inserted, it is difficult to twist it. In this case, you must find a way to unlock the door lock. First determine whether the door is opened inward or outward. If it is opened inward, pull it in. If it is opened in the outside, push it inward.
