Review on Affordable 2pcs Key FOB Shell Remote Case Replacement For 2002-2005 Mini Cooper R50 R53 Without Chip by Thasapon Bowers

Fairly easy to swap everything out for a new case. I actually had to unscrew the original key that comes with the new case to get it to fit. The key blade that comes with the cases is cut off where the pin goes to keep it in place. It's thinner in the new case, so you'll have to grind the blade of the original key to make it fit. I used a Dremel tool to sharpen the blade of my wrench and it fits snugly and securely. I also used some hot glue to secure the fob electronics in place as many reviews have mentioned that it floats in the new case. I also used some super glue to attach the plastic piece to the release button. If you're a bit mechanically inclined, this should be a fairly easy swap for you, along with a cost savings from not having to go through the dealer and pay over $200. The tools I used for the replacement were a small pair of needle nose pliers, a set of small flat head screwdrivers, a small punch to knock the pin out of the key blades and a small hammer. And of course a Dremel to sharpen the bit of the key. I found the mini logo sticker for the release button on ebay, which also had to be cut to fit the plastic part of the release button.
