Method for replacing the battery in a Changan CS75 car key: First, use a flat-head screwdriver or a similar tool to pry open the remote control shell, then remove the old battery. Place the new battery with the positive side facing down into the slot. After installing the battery, cover the remote transmitter lid. The Changan CS75 is a compact SUV under the Changan brand, with dimensions of 4650mm in length, 1850mm in width, and 1705mm in height, and a wheelbase of 2700mm. In terms of appearance, the vehicle features a large horizontal grille that integrates Eastern aesthetic design concepts, complemented by refined chrome grille lines. Additionally, it includes dynamic chrome trim kits, enhancing the vehicle's quality and overall appearance.
I've been driving the Changan CS75 for over three years, and when the key fob battery is low, the remote unlocking becomes less responsive. I'm quite skilled at replacing the battery. There's a thin seam on the back of the key; you can pry it open with a coin or a small screwdriver. Remove the old small button battery (model CR2032, available at supermarkets), making sure not to place it upside down by noting the positive side marking. After closing the cover, test the remote. If it doesn't work, the cover might not be pressed tightly enough. I usually keep the tools handy, which saves both money and time compared to going to the 4S shop, but be careful not to pry too hard to avoid cracking the plastic shell. The battery typically needs replacement about once a year, which can extend the key's lifespan.
