A remote control apparatus for a saddle-type vehicle such as a two-wheeled vehicle includes a transmission antenna for transmitting a signal to a normal portable transmitter carried by a vehicle user. The transmitted signal urges the portable transmitter to transmit an ID signal to a receiver positioned on the vehicle and operably connected to a handlebar lock module. The transmission antenna is disposed within the vehicle body cover at a position spaced away from the handlebar lock module. Upon receipt of the ID signal, a handlebar lock module provides a handlebar lock cancellation operation allowing operation of the vehicle. The invention greatly increases the degree of freedom in arrangement of the transmission antenna.
