ABSTRACT:
The invention relates to a vehicle use, wireless signal controlled locking and unlocking system. This system includes a user-carriable, userside controller and a vehicle side controller. The former controller takes the form of a card. Both these controllers are mutually communicatable by way of wireless communication and adapted for control of door-locking and unlocking operations. Switches are provided at the vehicle outside door handle and trunk, while a buzzer and a timer are provided within the vehicle interior. The buzzer is operated for a predetermined short time period, for instance 5 seconds, when the door has been brought to its locked position under such a condition that when the userside controller had been left in the vehicle with carelessness. In this case, however, the door can be opened by simple manipulation of the handle switch so far as the buzzer is kept in operation.
