My wife's 2008 LR2 is having key fob issues. She only has one key, it will start the vehicle however it will not unlock or lock the vehicle. I originally thought it was a battery issue but after replacing the battery the issue remains. We live 500 miles from the nearest dealership so my idea was to purchase a virgin key fob off of ebay (from china). I found a lock smith about 100 miles away that said he could clone the new fob as long as I have the current fob that works. So far I've found mixed reviews. Will this work or do I have to travel all the way to the dealer?
