    Do you use a double fast lock door? 1；If you remove the handle first [there are two screws on the inner handle of the door], see if the square pin inside is plugged in, if it is plugged in, otherwise you can't fix it yourself. 2；If it is a mechanical lock, it may be that the pin in the handle is short, insert or change the pin, and remove it as above.

    There are several situations when the handle is pulled down and the deadbolt does not return (the door cannot be opened).

    1. The pin under the handle handle is not installed or not installed.

    2. The spring of the pin under the handle handle is broken.

    3. The pin under the handle handle is too short.

    4. The lock is broken (worst-case scenario).

There may be two reasons for the difficulty of unlocking, one is the lock cylinder (poor lubrication, treatment: use a pencil foam to put on the key and then insert it into the lock cylinder and plug it back and forth), one is the lock point (the lock body lock point and the side lock point, this needs to be checked, if the side lock point is not sensitive, it will also lead to difficult unlocking. ）
