2 Answers
The steps to replace the battery in a Changan CS75 key are: 1. Use a flat-head screwdriver or a similar tool to pry open the remote control shell; 2. Remove the discharged remote transmitter battery; 3. Place the new battery with the positive side facing down into the compartment; 4. After installing the battery, cover the remote transmitter lid. Taking the 2021 Changan CS75 as an example, its body dimensions are: length 4650mm, width 1850mm, height 1715mm, with a wheelbase of 2700mm. The 2021 Changan CS75 is equipped with a 1.5L turbocharged engine, delivering a maximum horsepower of 178PS and a maximum power of 131kW, paired with a 6-speed manual transmission.
Speaking of changing the battery for the Changan CS75 key, I’ll share my experience: There’s a small gap on the back cover of the key. Use a small flat-head screwdriver or a plastic card to gently pry it open—don’t apply too much force to avoid scratching the shell. Inside, you’ll find a CR2032 coin cell battery. Pay attention to the battery’s polarity markings—the positive side (+) must face upward for it to work! After removing the old battery, insert the new one, ensuring it’s placed correctly, then snap the cover back into place. Finally, test the key buttons to check if the car door responds normally. The whole process takes about 5 minutes and is quite simple. A reminder: Before starting, work on a clean surface to avoid static damage; batteries are cheap to buy online, and DIY replacement is hassle-free and cost-effective. However, the shell clips are fragile and can break easily, so handle them gently. After replacement, make it a habit to test all functions to prevent unexpected failures.
