The Mercedes-Benz C200 is a high-end family car with a body length, width, and height of 4526mm, 1728mm, and 1427mm, respectively, and a wheelbase of 2715mm. In terms of appearance, the Mercedes-Benz C200 features a glossy black B-pillar design, with bumpers and protective strips in the same color as the body and chrome trim.
Actually, I often replace the battery for my Mercedes C200 key. Here's how I do it in a few simple steps: First, prepare a CR2025 button battery and a small flat-head screwdriver. Press the silver button on the back of the key to pull out the mechanical key blade, revealing the slot opening. Carefully pry open the key's back cover with the screwdriver, being careful not to scratch the casing. Once opened, you'll see the circular battery - use a toothpick or plastic tool to remove the old one. When inserting the new battery, remember to align the '+' positive side upward against the holder and press it gently flat. Finally, snap the back cover shut and reinsert the mechanical key until it clicks into place. The whole process takes just three minutes, saving you over 200 yuan compared to going to the dealership. Plus, doing it yourself lets you choose higher-quality batteries that last longer than the factory ones.
