There are two screws on the back cover of the car key. Use a screwdriver to remove each screw separately, then open the back cover to reveal the compartment. Remove the old battery, install the new battery, then reattach the back cover and tighten the screws.

I've used several Refine S3s, and changing the key battery is quite simple: find a small flat-head screwdriver or coin, gently pry open the back cover along the edge gap of the key to reveal the CR2032 coin battery inside. When removing the old battery, avoid pulling hard; carefully place the new battery with the shiny side facing up (corresponding to the key surface label). After installation, press the cover firmly and test the remote function to ensure it works properly. The key is well-designed, but don't use too much force when prying to avoid damaging the plastic clips. Keep it dry to prevent short circuits. For batteries, it's recommended to choose durable brands like Panasonic and check for replacement every two years. If the key buttons respond slowly, replace the battery early to avoid being unable to open the car door. This kind of DIY maintenance saves time and hones your hands-on skills, making it a popular tip to share with fellow car enthusiasts.

As an average car owner, I've driven my Refine S3 for over three years and just replaced the key fob battery last week.

If the buttons work to unlock after replacement, you're good to go. No need to buy professional tools - it's that simple; batteries are affordable, starting from just 5 yuan, available online or at supermarkets.

My Refine S3 is an old car, and I always replace the key battery myself when it runs out. Prying open the back cover with a hard card is the most convenient method. The battery is a CR2032—remember to place it with the convex side facing down into the slot when replacing. After installing the new battery, test the buttons to ensure they work properly; if not, check if the contact points are clean. In the past, I’ve forgotten the orientation a few times, so now I mark the battery to avoid confusion. Frequent key malfunctions may indicate aging circuits that need inspection; keeping it dry can extend battery life. My DIY maintenance habit has saved me a lot on service fees, and common household tools are sufficient. Sharing this experience with friends has been very helpful.
