I have a 2000 Seville STS that was given to my wife as a gift. The car came with 2 ignition keys, both #2. These keys allow only certain functions , such as, drivers side window, drivers side door mirror and manual door lock. Does a #1 key enable the other window and door functions? Can I obtain one at a Cadillac dealer or is there a malfunction in the switch panel. HELP. louis7808.
