During my lengthy (and continuing) illness, my lovely wife managed to lose both my full function and valet keys. Now my car is sitting in the driveway with the doors locked, and a dead battery. I have no way to enter the car. What are my options. I assume I have to buy a blank, have the car towed to the dealership and let them get the key code and cut a key. Then they should be able to open the car and program the car/key. Am I right?
