So, the door can't be opened from the outside, not even with a key. Easy to install or remove, this door lock can be installed in seconds without any tools, even in emergency situations and in the dark. Just insert the metal piece into the door lock slot, close the door, and then put the red handle groove to the stud on the metal sheet, then no one can open the door from outside.
