This is a great post. My FOB works fine but is broken from being dropped and the buttons are all cracked. The panic button actually lost the "pusher" under the plastic so it's not even useable anymore.

Ok, since this has been a couple years since this post and I can't seem to find any on ebay. I did find this one for MB:
eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices
It looks like it does not have the red lens on the front. Does anybody know a specific MB model that uses the exact same FOB? Where can I get a replacement plastic case?
