I have disassembled and assembled this kind of door with a good soft package, and basically all of the panels have been replaced, and some of them have even destroyed the soft package. So you must be careful when installing, the door lock is loose and it is not necessarily a matter of locking, see if the screws on the outside are loose.
If you loosen it tightly, see the effect.
There is a special unlocking and door-to-door service, but it must be approved by the Public Security Bureau and guaranteed.
Not necessarily the door is broken! Generally, there is a small pimple on the inside of the security door, and if you twist it, the key on the outside will not be opened. It's the last level that locks it. >>>More
1. The lock cylinder is faulty.
2. Failure of the lock body. >>>More
1.The spherical lock will be reversed, the person is locked in the room can not go out or enter, with the key can not be opened, that is the oblique tongue lock latch off hook failure, the grip idling can not drive the oblique tongue when the person is inside: find a small wire in the place located in the neck of the grip There is a small hole, insert the flat tenon grip and pull it out at the same time, grasp the handle and pry open the cover, there are two fixing screws to turn open, the lock body is pushed out only when the oblique tongue is left, and then find a needle-nose pliers or a flat screwdriver, and the oblique tongue will drive the hook to the horizontal dial and do not let go, After letting go, it will bounce back, Push the door open again. >>>More
It should be that the key rotates 360 degrees back to the original position to take out the key, if it does not return to the original position to take it out, the lock cylinder is easy to break, and it is best to change the lock cylinder if it does not return to the original position.
