Well, you have 2 keys. one remote with buttons and one valet key with no buttons and no remote controls. The one with buttons have 2 forms of programming required. First, for the remote function to control the doors and/or windows, the second to start the car itself with the key in the ignition. You can program the remote function yourself with a door procedure, however ,the key itself can only be programmed by the dealer for the car to start. The same programming applies to the valet key.
