The Changan CS75 is a compact SUV under the Changan brand, with dimensions of 4650mm in length, 1850mm in width, and 1715mm in height, and a wheelbase of 2700mm.

I previously drove a Changan car and found that key battery depletion is a common issue, with batteries typically lasting one to two years. When replacing, first confirm whether your key is a mechanical button type or a smart remote type. Most Changan keys have a screw-secured casing, so find a small Phillips screwdriver to remove the screws and gently pry open the casing. The internal battery is often a CR2032 model, installed with the positive side facing up. Before removing the old battery, note the installation direction to avoid placing it incorrectly. After installing a new battery of the same model, snap the casing back on and test if the buttons respond normally. If the light still doesn't turn on after replacement, check if the battery contacts are corroded and try cleaning them. It's recommended to purchase high-quality battery brands like Panasonic or Energizer to prevent leakage damage. The entire process can be done yourself in five minutes, saving both money and hassle. Don’t forget to regularly check the key battery level to avoid malfunctions while driving, which could affect safety.
