A communication system and method for keyless-entry alarms includes a vehicle-mounted alarm transducer (215) controlled by a vehicle-mounted control system (250) that includes a receiver (207). The system also includes a hand-held R.K.E. transmitter device (200) for transmitting a radio-frequency message. The vehicle-mounted alarm transducer (215) is deactivated when receiving the transmitted radio-frequency message. If the vehicle-mounted alarm transducer (215) was active when it was deactivated, and a deactivate-alarm command code is not received in the radio-frequency message, then the vehicle-mounted alarm transducer (215) is reactivated after the transmitted radio-frequency message is completely received and decoded.
