It can be done, but be prepared for some expense. Since you have keys I think you need the fob (not the key combo) in the first source. It is also not on-board programmable, so you will have to pay for it to be programmed into the car by an automotive locksmith or the dealer. You can call the source and verify what you are up against. I have used them and found them reliable, but I have never spoken to their customer support.
