Method for replacing the battery in a Changan CS75 key: 1. Use a flat-head screwdriver or a similar tool to pry open the remote control casing; 2. Remove the depleted remote transmitter battery; 3. Place the new battery into the compartment with the positive side facing downward; 4. After installing the battery, close the remote control casing. Taking the 2021 Changan CS75 Glory Million Edition 280T Manual Elite as an example: It is a compact SUV launched by Changan Automobile, with dimensions of 4650mm in length, 1850mm in width, and 1715mm in height, and a wheelbase of 2700mm. It is equipped with a 1.5T turbocharged engine, delivering a maximum power of 131kw, and paired with a 6-speed manual transmission.
I've been driving the Changan CS75 for several years, and changing the key battery is something I do myself to save money and hassle. The steps are actually simple: find a small gap on the back of the key, gently pry it open with a dime coin or a flat-head screwdriver, but don't use too much force to avoid damaging the case. Inside, there's a silver button battery, usually model CR2032, which costs just a few bucks at the supermarket or online. Remove the old battery, check the positive and negative markings—I forgot this the first time and installed it backward, causing it to malfunction, but just reopen and correct it. Place the new battery back the same way, with the positive (+) side facing up, and snap the cover back on. Test the remote lock/unlock response immediately—if it's quick, you're done. Usually, if the key's remote range shortens or the buttons become sluggish, it's time to replace the battery; the lifespan is about two to three years. I keep a few spare batteries in the car just in case. To maintain the key, avoid dropping or getting it wet to prevent premature damage, and practice more to get better at it. In short, it takes just five minutes and saves unnecessary expenses.
Changing the battery in my Changan CS75 key was a fun and easy experience. The key has a small slot on the back—just insert a coin, twist, and the cover pops open. Inside, there's a common CR2032 button battery, which is cheap to replace. After removing the old battery, check the polarity markings to avoid mistakes, then insert the new battery the same way. Close the cover and test by pressing the lock button—if the light comes on, it works. Before the change, my key remote was sluggish, but it became instantly responsive with the new battery. DIY saves a trip to the repair shop and avoids queues. The whole process is just three steps: open, replace, test. To prolong battery life, avoid leaving the key in direct sunlight or damp places. Don't worry about damaging it—Changan designed it to be user-friendly, simple, and safe. Keep a small toolkit at home for quick access—super convenient.
The basic steps to replace the battery in a Changan CS75 key are to pry open the back cover and remove the old CR2032 battery. Use a small tool to gently create a gap and remove the cover without applying excessive force. When inserting the new battery, ensure the positive terminal marking aligns with the internal positive contact to avoid malfunction. After testing the functions, securely close the back cover to complete the process. The operation is simple, and the required tools and batteries are commonly available in supermarkets for just a few dollars. Ensure the contacts are clean and free from oxidation, and perform regular checks to extend battery life and save on repair costs.
