These keys usually are around $45 at the dealer. Some dealers will program the keys for free if you buy the key from them, but some dealers charge as much as $100 to program a key! It all depends on your local dealer. Since it looks like you are in Alaska, you probably don't have too many options. Why don't you call your closest dealer and ask?; they might be good guys and not charge you for programming. (then again....)
Programming a key is simple, takes just a couple of minutes, tops.
