Anonymous users2024-01-24The inflexible solution to the anti-theft door lock is mainly to add lubricant to the inside of the door lock, so that its interior is fully lubricated, and the door lock is easy to dredge.
The use of kerosene as a lubricant effect is particularly good, now there are boxes of small packages of kerosene in the small commodity market, this kind of box will have a pointed small mouth, we only need to squeeze the sharp mouth at the keyhole a few times, kerosene can flow into the keyhole, and after a few minutes, we will take the key to unlock it, and the key can enter smoothly.
If you think kerosene is too oily or smelly, you can also find a pencil, sharpen some pencil leads, and slowly sharpen them, the finer the better, the main ingredient of pencil leads is graphite.
Carefully get the sharpened pencil lead graphite onto the key, and lay the key flat. Carefully insert the key into the lock hole and gently plug it back and forth a few times. Turn the key 180 degrees, add graphite powder to the other side, and plug and unplug it back and forth a few times to get back to normal.

The first step is to use the key in your hand to push hard twice on the outside, and if the key inside is horizontal, it can be pushed out. The problem is easily solved, and the jack can be twisted out.
The second step, if it doesn't work after a few strokes, don't hit it with a hammer or brick, you can hit it out like netizens said. I can't get through it if I try a new security door in person. It also breaks the lock!
The third step is to find an X-ray from the hospital. There is no way to find two unlocks, and they are all this way to open, to see if the lock on the crack of the door can be opened. This trick thin door can.
Fourth, because I pretend that the door is thick, there are grooves in the door. The previous step cannot be opened. At this point, we can only destroy the door, which is also the method of unlocking, in fact, the 50 yuan of unlocking can be saved.
Fifth, don't worry after the handle falls off, in fact, what is broken is only the shell of the lock, and the intermediate structure such as the lock cylinder is not broken. Just buy a shell and go to the lock shop. 50 bucks to buy a good one.
The unlocking company gives an opening fee of 50 yuan, and the handle is 150 or 200 yuan. It's easy to earn!!
