A few days ago, I just replaced the battery for my family's Volkswagen key and found it quite simple. My key is the folding type like the Volkswagen Polo, with a small gap on the back. You can gently pry open one side of the shell using a small coin or a thin card—just don’t use too much force to avoid damaging the plastic clips. Once opened, the battery compartment is exposed. The old battery is usually a CR2025 or CR2032 model. Use your fingernail to remove it, then insert the new battery, making sure not to reverse the polarity. After installation, close the shell and press the buttons a few times to test the remote. If it works normally, you're done. It’s worth noting that key batteries typically last about two years. When the battery is low, the remote range will shorten—don’t wait until it completely fails to replace it. Regular checks can save you trouble. When replacing the battery, it’s best to do it in a well-lit area to avoid losing small parts on the floor.
