It depends on your trim. If you have the keyless enter-and-go (push button start), the fobs get pricier.
I do have that with my Longhorn, and my dealership has them in stock typically. Didn't ask about a spare for mine when we got the 2014, as it came with both keys. On my 2013 when we bought it last year (same fobs), it only came with one, and I negotiated a second one into the purchase at no cost to me. Salesman told me they were $300 and some odd dollars (he gave me an exact number, but I cannot recall what it was, just that it was over $300 but less than $400). That was for fob, programming, and cutting the "manual" key that slides into the fob.
