Abstract: In a vehicular portable device, a display unit is controlled to display an icon representing an instruction to an in-vehicle device when detecting that an acceleration equal to or greater than an activation threshold occurs in the vehicular portable device, a pressing force at an icon selection position, which is a position where the icon is selected by a touch sensor, is detected, and a control signal instructing execution of a command corresponding to the icon being selected is transmitted based on detection of the pressing force in a state where the icon is selected.

Abstract: An electronic key includes a mechanical key, a key housing to which the mechanical key is attached, and a charging terminal. The mechanical key is detachable from the key housing. The charging terminal is disposed in a key opposing surface that is a surface of the key housing, covered with the mechanical key in a state where the mechanical key is attached to the key housing, and exposed when the mechanical key is relatively moved from a position attached to the key housing.
