To replace the battery in a Changan car key, I've done it a few times myself. The key usually has a shell with clip designs, and there are small gaps on the front or side. You can gently pry it open with a fingernail or a small flat-head screwdriver. Once the shell is separated into two halves, you'll see the internal button battery inside. Common models are CR2032 or CR2025—make sure you don’t buy the wrong one. When removing the old battery, avoid using excessive force to prevent damaging the plastic clips. When installing the new battery, ensure the positive and negative poles are correctly aligned; otherwise, the buttons won’t work. After replacement, press the shell back together, making sure the clips are aligned and securely fastened. The whole process takes just a few minutes, and the key’s functionality will be restored. Regularly replacing the battery can prevent sudden locking issues, so it’s recommended to check it every two years. There are also tutorial videos online to assist with the operation.
