Hello and welcome to just answer. Let me see if I can help you with this. Sounds like your Wireless Control Module (WCM) has failed. We see this every now and then. Try this: Disconnect the negative battery cable for about 2 minutes and then reconnect it. See if it will start. If it does, then get the car to the dealer and have the WCM replaced or the software in the WCM updated. If the battery disconnect/reconnect does not help, then get the WCM replaced and programmed to your key(s).
I hope this information helps, and let me know if you need further assistance with this.
