I just got my 2016 Genesis two weeks ago and ordered the Wallet Key Fob today from the Ebay, can't wait to try it out.
Replacing the battery in the Genesis G80 wallet key is a bit tricky. Use a small screwdriver and insert the tip into the slot on the backside of the wallet key and then just force it open. the replacement battery is a Panasonic CR2412. You can get at Walmart or on Amazon pretty cheap. View attachment 20371
