The bathroom door lock is broken. How can I open it without a lock cylinder?

1, if you have strong hands-on ability, you usually lock it in the room, and the lock inside can be removed with visible screws. It is recommended to bring a screwdriver in the room.

2. If you can't open the door yourself, you are advised to call your relatives and friends for help, or directly call 1 10 for help.

First, because the safety bolt button in the door is loose, the safety bolt shakes when closing the door. The lock core can be turned with the original key, but the door can't be opened. Some people, because someone was at home and had something at the door, put on the safety bolt first and forgot for a while; When closing the door, the oblique tongue of the lock forcibly closes the door without shrinking.

Second, yes, there are children who are not sensible at home, and elderly people with Alzheimer's disease. They accidentally put on the safety bolt at home and can't open the safety bolt, causing outsiders to use the key to unlock the lock. Because the door is locked with a safety bolt, it still can't be opened.

Third, the door lock of the safety split is locked with a safety bolt and cannot be opened with a key. Solution: There are two kinds of buttons for the safety bolt on the lock box inside the security door: one is a twist button, and the other is a push button. The latter method can only deal with button insurance.

The above method can deal with more than 90% invalid locks of safety bolts. Another stupid method is to use an electric drill to drill a circle of holes in the lock box on the door, and then pry up the drilled holes, so that you can directly see the stopper of the safety mechanism inside, and then use a screwdriver to pull the safety plate. It is also possible to install a circular multi-tooth drill clamp specially used for drilling lock clamp holes on the iron gate to drill holes.
