Abstract
An easy-to-use remote keyless entry system is provided. To execute 2-way long distance communication at a low output and within a short time, transmission is effected while a data rate of a terminal board is changed. To reduce battery consumption in a system capable of setting an automatic output mode, the operation mode is shifted to the automatic output mode when an automatic output mode button is pushed or when a door lock release button of an operation button, etc, is kept pushed for a predetermined time. To execute a reserved operation at a reserved time, a storage circuit for storing reservation is provided to the terminal board.
