PROBLEM TO BE SOLVED: To enhance the safety and serviceability of a vehicular keyless entry device. SOLUTION: This device includes a passive entry mode and an active entry mode. In the passive entry mode, communication between portable equipment and a fixed machine is triggered by operation of an outside handle and predetermined control is effected if identification codes are coincident (S11-S18). In the active entry mode, the communication is effected by operation of an unlocking switch or a locking switch and predetermined control is effected if the identification codes are coincident (S19-S21). If locking is done inside the vehicle or if the portable equipment is detected to have been left behind in the vehicle, a function stop flag for stopping the function of the passive entry mode is set (S16). This prevents unauthorized persons from intruding into the vehicle, whereby safety and serviceability can be enhanced. |
