Just hold the key and twist the other end. It even has gum on it and I think it was made for that purpose. This makes it easier to put on and take off. I don't know about his safety. I think a grinder, a hammer, or maybe even a screwdriver could easily hit him, but it might slow them down enough to look for something else. It all depends on where you park. I would take a picture of someone trying to physically get him out of the RV and I hope the others at the campsite do too.
