I've been driving the Changan CS15 for several years and have gained plenty of experience in replacing key fob batteries. If the key stops working or the signal weakens, it's likely time to change the battery. The battery model is usually CR2032—make sure not to buy the wrong one. The replacement process is simple: first, check for small gaps along the edge of the key, then gently pry open the casing with a fingernail or thin tool. If it's too tight, carefully unscrew it with a small screwdriver. When removing the old battery, note the positive and negative positions to avoid reversing them. After inserting the new battery, press it firmly and reassemble the cover. Test the remote to ensure it works properly. A reminder: avoid leaving the key in damp places to prevent short circuits. Having replaced it a few times, I've saved trips to the repair shop. Regular maintenance can also extend the key's lifespan—this small DIY task saves both money and hassle.

As a hands-on expert who often helps friends with car repairs, I recommend DIY key fob battery replacement to save dozens of yuan. On the back of the Changan CS15 key fob, there's a small groove—use a plastic card or nail file to gently pry open the casing without excessive force. The old battery is a CR2032 model, available at hardware stores for just a few yuan. When installing the new battery, ensure the positive side faces upward and fits securely, then snap the cover back on. Test the key buttons—they should emit a beeping sound. I've also used a multimeter to check voltage; if it's below 3V, it's time to replace. The process just requires some care. A basic tool set bought online costs around ten yuan, much more cost-effective than shop services. Worth trying for those with good hands-on skills.
