A small-sized electronic security system superior in emergent response and capable of obtaining power from other electronic apparatuses even in the case in which a portable electronic key suffers from battery exhaustion, and a remote-operating portable electronic key therefor are obtained. The electronic security system is applied to a remote-operating system for in-vehicle equipment. The electronic key is composed of an electronic key housing on which a power supply is mounted and an electronic key module arranged to be able to be detachably attached to the electronic key housing and provided with a transmission/reception antenna, signal verification means, and operation control means for the in-vehicle equipment. The electronic key module has a feeding terminal layout common to an interchangeable module of another electronic apparatus and an outer shape identical thereto so that the electronic key module can be interchanged to the another electronic apparatus for an emergency operation in the case in which the electronic key module becomes inoperative due to battery exhaustion in an normal operation condition of being inserted in the electronic key housing.
