I encountered this issue once when driving to go camping. The remote key suddenly stopped working, and the start button didn't respond. I panicked a bit at the time, but then remembered I always carry a spare key in my pocket. I immediately took out the mechanical key blade, opened the car door, found the ignition slot under the steering wheel, inserted the key, turned it, and the car started smoothly. Later, upon checking, I realized the remote battery was dead. It only took a few minutes to replace it with a new one myself. Now, I regularly check the key's battery level and have an extra spare hidden in the car's trunk just in case the original fails. Remember, remote failures are mostly caused by dead batteries or water-induced short circuits. Keeping a CR2032 coin cell battery at home as a backup is a necessary habit. In emergencies, avoid forcibly prying open the remote, as it might damage the internal chip and increase repair costs.
