I'm the owner of a Baojun 310. Last time when the key wasn't working, I guessed the battery was dead and replaced it myself—it was quite simple. First, find a flat surface to work on to avoid losing small parts. The key usually has a small seam on the back cover; use a thin blade or coin to gently pry it open, but don't use too much force to avoid damage. Once opened, you'll see a small round battery, CR2032. Pay attention to the markings for the correct orientation—remove the old one and insert the new one the same way. You can buy these at supermarkets or online for about ten yuan. Then, close the cover, press it firmly, and test the remote. Usually, you can test the unlock function when you approach the car. Regularly replacing the battery every two years saves hassle and prevents sudden failures on the road. Doing it yourself saves time and money—no need to rush to the 4S shop for everything. During the process, be careful not to touch the circuits and remove static electricity from your hands to prevent short circuits.

For friends looking to save money, I always DIY the replacement of my remote key battery. The Baojun 310 key shell pops open easily with a little pry. Use a hard card or a small screwdriver from home, push at the gap to open it. Just replace the old CR2032 battery with a new one—costs only a few bucks, no need to spend big money getting someone else to do it. When inserting the new battery, make sure the positive and negative sides are correct. After putting it in, snap the shell back on and test the remote range—if it works normally, you're good. Keep things clean during the process to avoid dust interference. Usually, keep the key in your bag to avoid bumps and extend battery life. If it doesn’t work the first time, try again—it usually takes just five minutes. Remember, buying branded batteries is more reliable—don’t cheap out on low-quality ones.

I was initially worried that changing the battery might damage the key, but the actual operation turned out to be super simple. Place the key in a comfortable position, feel for the small groove on the back cover, and gently pry it open. Remove the old CR2032 battery, noting its orientation, then insert the new one exactly the same way and press the cover firmly. The 3V round battery is widely available. After closing it, test the remote function. If it doesn't respond, check if the battery is not installed tightly. Be gentle throughout the process to avoid scratching the key. After the replacement, it feels really convenient, and I won't panic next time I encounter a similar issue.

The key to replacing the battery lies in choosing the correct model. I understand that the Baojun 310 uses a standard CR2032 3V lithium battery. When opening the key, look for the side gap, and avoid using tools that are too sharp to prevent damaging the casing. The battery has a plus sign indicating the positive side should face upwards. After replacement, the remote will respond more sensitively and have an extended range. It is recommended to purchase well-known brands like Panasonic to avoid leakage, with a lifespan of one to two years. Replacing it yourself is more convenient than seeking help, and having a spare new battery ensures you won't be caught off guard at critical moments.
