@thewayeverythingworks: Hotwiring refers to an old method once used to start certain vehicles without a key by bypassing the ignition system. Early cars relied on simple electrical circuits, where turning the key merely sent power from the battery to the starter motor. Because of this simplicity, connecting the correct wires could activate the engine even without the original key. While it was sometimes done legitimately by mechanics or owners who had lost their keys, the technique also became associated with car theft. As a result, modern vehicles now use immobilizers, coded keys, and electronic security systems specifically designed to prevent hotwiring altogether.
