Thanks for the excellent write up and photographs. It was very helpful!

I purchased the http://www.ebay.com/itm/130635875647?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT. The quality is not quite up to OEM, but for $20 delivered it is very good. I ordered a spare to have just in case.

Mine was glued around the full perimeter and took some coaxing, but also had the white retainer which made the transponder chip swap very easy.

I reused the OEM spring as it was higher quality.

One tip for those having trouble with the key staying locked closed: trim the flashing on the retain slots to firm up the button seating. A little trim with a sharp knife or razor blade and it will lock up tight.
