Went to Chumash Casino today and, much to my amazement, they had a new room key. According to the person at the registration desk, they started using this key/slotcard yesterday (5/29). Sorry but I don't have any extras available to trade at the moment, but I'm sure I'll get back there in the near future (and hopefully they'll become a little more generous with them once they've been out for awhile). The card wasn't available at the Slot Club desk, but is (currently) only available at check-in, and is used as both a room key and slot card for those staying at the resort.
