How to open the security door?

In the first case, if you live in a single room and there is a portal next to the door, if the window is not far from the lock and the window is not rotten, you can use a stick or find someone with a longer hand to help open the door.

In the second case, if the matter is not urgent, and the family still has the key to the door, call the family member and ask him to come back and help open the door.

In the third case, if it is an ordinary door or a bull's head, and there is a bit of a gap in the door gap, you can use some hard cards to insert into the door crack next to the lock, and push it all the way in, so that you can open the door by opening the deadbolt.

In the fourth case, if in a big city, the door is a relatively strong anti-theft door, and the key of the whole family is in the room, then you can call the locksmith to help open the lock, and then change it to a new one.

In the fifth case, if the situation is more urgent, you can only kick the door with your feet or hit the door with your body, and then you can only change a lock, or even change a door.

In the sixth case, see if you can still get the key through the window with a round grip tool, if you can't do it, you can also use a flathead screwdriver to insert it into the lock hole, keep turning, and if it doesn't work, use a hammer to keep hitting the lock until it breaks.

You don't have a lot of credibility, and you think it's so easy to open.
