Summary: | A control system comprises a remote control system and a keyless entry system. The remote control system has an electromagnetic wave communication system including a portable transmitter transmitting a signal modulated in accordance with a code and a receiver provided in the motor vehicle to receive the modulated signal and to demodulate it to produce a code signal. The code signal is compared with a registered code signal. When the code signal coincides with the registered code signal, an actuator is operated to lock and unlock a door. The keyless entry system has a manual operating device provided on a handle of the door. The manual operating device has at least one switch manually operated so as to produce an on-off signal. When the on-off signal coincides with the registered code signal, the actuator is operated. |
