I just got a new door for my Reo Grand and am having a small issue. I was hoping one of you might have a solution before I contact Rob. So I got the door and the 2 magnets come in a separate baggie with instructions to glue them but they don't quite fit. I got the first one in and it fit pretty well. It's just raised a tiny bit but the second one does not sit down in the hole enough to be able to slide the door in. I thought maybe I could sand the battery down but someone said that wouldn't work. Any other ideas? I figured someone else had to have had this issue and I was hoping there is something I can do to fix it myself. I really don't want to have to send it all the way back for just 1 magnet. Is there maybe a smaller or thinner magnet I could buy or a way to make the hole bigger? Any suggestions would be greatly appreciated! Thank you. 
Thanks for responding. I do have a rotary tool(like a dremel) and a 228 piece kit. Anything I can do with that?
Really happy to just get another because I scraped up the other one when I put it down on the counter and tried pressing the magnets in. It really did a number on the mirror finish.
Now it's beautiful.
