The creation of your Map Book is a series of steps. You need to perform each step correctly before proceeding to the next. If your Key Map is not consistent with your external reference, then you have an xref insertion issue, not a key map issue. Fix your xref before you make your Map Book.
I don't think you've defined your 'area' correctly. Also, the images in post 9 don't show your template on your layout. Please create your template first, not last.
As mentioned in post 6 of this thread, you should watch this 8 minute >>VIDEO<< .
The beginning of the video explains how to create your Main viewport and the Key View. Create the template first, before attempting to create your map tiles.
The video clearly takes you through the map book utility and provides clear instructions along the way. Pay attention to step 3, the creation of the Tiling Scheme. The instructions in this step will help you understand why your main viewport and key map are not in harmony. The tiling scheme section also explains how to Preview your map tiles, how to Refresh the Preview and how to Exit the preview. If you haven't realized it yet, your total map tiles, taken as a composition, is the same as the area shown in your Key Map. When you establish the map tiles then your Key Map will automatically follow.
In terms of creating map books, this video will be the best 8 minute investment you can make because it pays big dividends down the road.
