Have had a ton of problems with lost fob replacement, buying private, through ebay, etc.. Had to jump through many hoops, avoid dealers, go to private locksmiths, get
letters from locksmiths that could not program, etc, etc. Had BIG problems with AmeX, MC, getting my money back, finally did.
My conclusions:
1. Someone remarked on this forum that a new Genesis Key Fob could be programmed to one
VIN numbered vehicle only. It could be re programmed to that very vehicle, but no other. Seems to be a safety or security matter. Hyundai, and their dealers will not confirm this. I have come to believe it is true. It would be nice if we could get a "YES" or "NO" on this from Hyundai, for the benefit of us all!
2. Save your time and frustration and do without the spare, or cut the best price you can from your dealer on a new factory one. Life is really too short.
