just went to WalMart and they have some sort of aftermarket key that is programmed onsite. The machine supposedly reads the transponder & memorizes the key profile. It then programs & cuts the key. The final product didn't start my vehicle but it did unlock & turn the ignition. It costs $50 + tax and would be worth it if the programming was right. I didn't have the time to see if they could reprogram it. That wouldve been a nice savings if it did work!
