I find that its best to have the dealership do this. As I recall, there's some BCM work that has to be done when programming new keys and remotes.

 

I know this because one of my technicians lost a key to an 08 Legacy and we had to get a new key and remote programmed for the customer. We tried doing it ourselves, but it ended up having to go to the dealer.
