Carefully pry open the edge with a coin to remove the upper part. Take off the upper part. Handle with care to avoid losing buttons. Wrap the coin with a cloth to prevent scratching the smart key remote. Ensure the battery is installed correctly with the right polarity.
I often change my car key batteries myself, and it's quite simple. The first step is to check the key type—most have plastic shells that snap together. Find the seam, then gently pry open the shell using a small screwdriver or coin, being careful not to use too much force to avoid scratches. Once opened, you'll see the coin cell battery inside, usually a CR2032 model. When removing the old battery, note the positive and negative orientation to avoid mixing them up. Before replacing the battery, go to an auto parts store or supermarket to buy a matching model—I recommend choosing a branded one for better durability. When installing the new battery, ensure the positive side faces up and gently press it into the slot, avoiding direct contact with the metal surface using your fingers. Close the cover firmly, then test the remote functions with the key. Last time, I rushed and misaligned the battery, causing it not to work, so I had to reinstall it—now I take my time. I also keep a few spare batteries in the car's tool kit. The whole process takes less than five minutes and saves me dozens in repair fees!
