From your love for this.

Judging by the situation, it is very good.

Bai can be neither, but the problem of the anti-theft door itself, because the domestic anti-theft doors are basically made of metal DAO, are relatively heavy, so the door will easily cause the door to sag after a period of use, which directly leads to the situation that the door lock cannot be closed when the door is closed normally.

There is another situation, that is, the anti-theft door is not standard when it is installed, which causes the door frame to be squeezed badly and causes deformation, so the above situation occurs.

It is recommended that you can test it like this: in the state of the door open, test it with a key or handle, whether it is open and closed (insert it into the lock cylinder with a key and twist) laborious, if it is laborious, you can judge that it is a problem with the lock, if it is not laborious, if it is normal, then it is a problem with the door, and the door needs to be readjusted.
