I've changed the battery in my C200 Mercedes key a few times, and it feels quite simple. First, open the key casing—some models require a small screwdriver to remove the screws on the back, then gently pry open the shell with your fingers or a thin plastic tool. Next, remove the old battery, making sure to note the model (usually CR2032) and not to confuse the positive and negative terminals. When inserting the new battery, ensure the positive side faces up. After closing the casing, test the remote functions to confirm they work properly. I also recommend wearing anti-static gloves during the process to avoid damaging the circuitry. When buying batteries, opt for reputable brands and avoid cheap, low-quality ones. After each replacement, I notice the key responds faster. This method is cost-effective and convenient—just a bit of DIY, saving the hassle and expense of frequent trips to the dealership.
