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.
The steps to replace the CS75 key battery are straightforward: First, locate the seam on the back of the key and use a small tool to pry open the casing. Remove the battery compartment, noting that the battery model is CR2032. Carefully remove the old battery to avoid short circuits and replace it with a new one of the same model. After ensuring the electrode orientation is correct, close the casing and test the remote function. The entire process requires gentle handling to prevent scratching the plastic or damaging the circuit. It is recommended to wear insulated gloves. The only tools needed are a small screwdriver or a similar pry bar, and make sure to double-check the battery model to avoid mistakes. After replacement, it's best to check the door lock and ignition functions to ensure everything is working properly. Keep a spare key in a safe place as a precaution.
