Your going to have to try a hard reset of the vehicle. This is accomplished by disconnecting the battery for a period of time. Usually 30 min +. If this does not work then you are more than likely experiencing a failed AAM (All Activity Module) which controls the Alarm system. These do go out from time to time.
