The other day my car key stopped working, and after searching online, I found it was a battery issue. I used a coin to pry open the shell of my Changan CS75 key, took out the old CR2032 battery, bought a new one, and installed it according to the positive pole indicator. After reassembling, the buttons worked again—super happy! It saved me money and time, taking only ten minutes. I found guides and shared experiences on online forums, and everything has been working fine since. With my DIY experience, I recommend trying a battery replacement first if you encounter a similar issue.
