Changan CS15 key battery replacement tutorial: Toggle the switch: Toggle the small switch on the key; remove the mechanical key; after pulling out the mechanical key, you can see a gap around the key shell. Use a flat-head screwdriver or other thin tool to pry it open, moving along the gap in a circle until the two halves of the smart key separate. Replace the battery: After opening, take out the small battery inside and replace it with a new one, making sure the positive side is facing up; after replacing the battery, press the key shell back together; then reinsert the mechanical key, and the process is complete. Changan CS15: The Changan CS15 is a compact SUV under the Changan brand, with dimensions of 4100mm in length, 1730mm in width, 1635mm in height, and a wheelbase of 2510mm.
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.
