I remember once when I was driving my to go hiking, the battery suddenly died in the mountains, and I couldn't open the door no matter what. Later, I discovered a hidden small panel under the driver's side door handle. I gently pried it open, inserted the physical key, turned it, and the door opened—I never thought it would be that easy. Since then, I've made it a habit to always carry the mechanical key in my pocket when parking and to keep a portable power bank in the car. Preventing battery aging is also crucial; I recommend checking the battery's charge every two years to avoid being helpless in unfamiliar places. These little experiences make me feel more at ease while driving.
