The big problem is that the keys are programmed for your vehicle. The keys have a chip in them that prevents any key from being pushed in and turned. You have to have the chip transmit the code. Check your manual for how to program the key. I would reset the program and set it to only the key and Fob that you have preventing theft by the other key and fob!
