Abstract: An electronic key without a power supply is used for unlocking an electronic door lock of a means of transportation such as an automobile or for unlocking an anti-theft system electronic lock. On the means of transportation, a building, a cabinet or an independent electronic lock, a solar power generation component and a battery that can be replaced externally are installed to supply power to a recognition device such as the electronic key and the electronic lock. An electronic passcode remote control key is firmly fixed on the means of transportation or an outer wall of the building, said key being easily removed and installed by an owner; and may be installed on or around the driver dashboard of the means of transportation, facilitating startup of an engine. A smart mobile phone or the like is used as a key to unlock the door lock of the means of transportation or the building and the anti-theft system lock. This solves the problem that a lock cannot be unlocked when a mobile phone battery is used up.
