    Answer: If it does not affect the security performance of the security door, you can do the following:

    Use sandpaper or a set file to smooth the burrs at the cutting part of the knife;

    putty at the traces (there are car repair shops);

    Paint the damaged area.

    If the wound is small, post a picture after the gold is flattened, and if there are more, change it.
