Doors are installed in every room in the home to play the role of sound insulation and privacy protection. For example, the bathroom will have a door lock to prevent other people from breaking in suddenly. However, some failures will occur when the door lock is used for a long time. For example, it can be turned but cannot be unscrewed. In this case, people will be locked in or blocked out. So what should we do at this time?
1. What should I do if the bathroom lock cannot be opened?
We need to find a sharp and thin knife, the sharper the point the better. Then press against the door of the bathroom from the outside first, and put the flexible part in the middle, that is, the lock shaft, to avoid contact with the lock groove to reduce friction. Then when inserting a sharp knife into the gap of the lock groove, bear against the lock shaft and apply force in the direction of the lock shaft. If it fails to open once or twice, please try a few more times.
2. What should I do if the door lock can be rotated but cannot be opened?
Usually, the door lock cannot be opened because the internal moving parts are stuck or rusted and cannot be rotated flexibly. Can be handled as follows:
1. Put some oil on it to lubricate, it can usually be opened.
2. Or try to insert the key, gently pull the lock up and down, and twist the key while pulling the key.
3. Try to use a discarded bank card or any other card, insert it from the deadbolt position, push the deadbolt, and open it.
4. You can also check whether there is any problem with the front and rear lock surface connecting columns. Reinstall and try again, or open the door if the square shaft has been in use for too long.
3. What to do if the anti-theft door cannot be opened
1. When opening the door, if the key cannot be fully inserted into the keyhole, if it is winter, please check whether there is any ice in the keyhole; if it is other seasons, please check whether there is any foreign matter in the keyhole.
2. If you hear the sound of metal friction when opening and closing the door, you can try to drop some lubricating oil on the hinge of the anti-theft door. If it doesn’t work, you can find professional maintainers.
3. Since the anti-theft door lock is often used, it has become the most problematic place on the anti-theft door. Therefore, it is very necessary to keep the lock. The main problem with the anti-theft door lock is that after using it for a while, it seems to be inserted. It is very difficult to key or extract the key. Sharpen the key a few times with a pencil, or blow a foam pencil into the keyhole to lubricate the key.
