Are you getting any error messages in the odometer area when you try to start with the key? Like "START ERROR" or like that? If the owner has another key to try it wouldn't hurt as the key can just suddenly decide to stop working. Usually if the DAS isn't happy it will give you a message in the odometer display area.
