cs75 key battery replacement method: 1. Pull out the mechanical key from the key by pressing the button on one side of the key; 2. After removing the mechanical key, you can use it to pry open the shell of the remote key; 3. Once a gap is pried open, you can slowly open the entire key; 4. Flip over the shell with the blue circuit board, and once the circuit board falls out, you will see the battery behind it. Replace it with a new battery and reassemble the key. The CS75 is a compact SUV under Changan, with body dimensions of 4650mm in length, 1850mm in width, 1705mm in height, and a wheelbase of 2700mm.
I remember feeling quite nervous the first time I changed the battery for my CS75 car key, but it turned out to be quite simple. My car key is the foldable type with a remote, and there's a small groove on the back. You can pry it open with a flat-head screwdriver, but be gentle to avoid damaging the plastic casing. The battery inside is usually a CR2032 coin cell—just check the old battery's model number to confirm, and don't use other types. When inserting the new battery, avoid touching the electrode contacts to prevent static electricity, align it properly, and snap the cover back on. I tested the remote locking function, and everything worked fine. The whole process took less than five minutes. Previously, going to the 4S shop would cost me tens of yuan in labor fees, but now I can just buy a battery online for a few yuan and do it myself—saving both time and money. If you're inexperienced, I recommend watching a video tutorial before attempting it. All you need is a small screwdriver; no other tools are required.
