Will a 2009 Scion tC master key work on a 2006 Scion tC?

My master key broke and I was looking to buy a new one, but the dealer is too expensive ($250 for the key and $89 for programming = $339 total). I found someone that is selling one for a 2009 Scion tC for much less and was wondering if that one would work with my older model.
