An in-vehicle emergency communicator for a vehicle with an external device is disclosed. The communicator includes a travel state information receiver for receiving travel state information from the external device. The communicator also includes a transmitter for transmitting an emergency message signal, which includes the travel state information, to a service center. The communicator includes a controller for performing an emergency message operation, in which the transmitter transmits the emergency message signal when an emergency message trigger signal is inputted and an ignition signal from an ignition switch is in an ON-state. The controller analyzes the travel state information when the ignition signal from the ignition switch is in an OFF-state to determine whether the ignition signal is out of order. When it is detected that the ignition signal is out of order, the controller causes an indicator to indicate that the ignition signal is out of order.
