I've replaced the battery in my Besturn B30 key multiple times, it's not hard to handle. First, find a small screwdriver or plastic pry tool. There's a small seam on the back of the key, gently pry open the shell without rushing, otherwise the clips can be easily damaged. Inside, it uses a CR2032 coin cell battery, which can be bought at supermarkets or online for around ten yuan. When removing the old battery, note the positive and negative directions—the + side usually faces a specific side, just install the new battery accordingly. Testing the buttons, like if the remote distance shortens, might help in troubleshooting. The whole process saves you dozens of yuan compared to dealership costs, but perform the operation on a tabletop to prevent losing small parts. By the way, cleaning the battery contacts can extend their lifespan, ensuring smooth unlocking every time.
