There is no one right answer to this question. But there are a few things to consider when you fix it. For things, you should fix it in a place that you will notice when you come inside and go out of the home. That way, you will always remember to grab the keys when you go somewhere. It should be in a location that doesn’t make it difficult to move about. So, avoid fixing them hallways that are too narrow. If you want the key rack to be a statement piece, consider fixing them on the living room wall or any other place where you entertain the guests.
