"Open your trunk. Find the wire harness that runs on the left upper side back to your tail lights. There is an unused connector about a foot or so from the tail light. Short and hold the connector (I used my key). The locks and trunk will cycle. Keep the connector shorted. After they cycle, push your trunk button on you remote(s). "
As for the keys, I got two brand new keys & cut for my car with the correct chip for $24.00 at the dealer.
