2 Answers
Steps to replace the key battery for Mercedes-Benz C200: 1. Push the small switch with teeth on the tail of the remote to the right, which will pop up a manual key; 2. After pulling out the key, gently insert it into the larger hole at the back of the key slot. Insert it about one centimeter until you touch the latch of the remote battery cover. Gently pry it open, and the cover will come off; 3. Open the cover by hand to see the remote's battery; 4. Press the battery lightly, and it will pop up. Remove it, replace it with a new battery, close the key cover, and reinsert the manual key. In terms of suspension, the front suspension of the Mercedes-Benz C200 is a multi-link independent suspension, and the rear suspension is also a multi-link independent suspension. For safety features, the Mercedes-Benz C200 comes standard with ESP, front side airbags, side curtain airbags, knee airbags, tire pressure monitoring, and more.
I often change the key battery for my Mercedes-Benz C200 myself, and it's quite simple. Look for a small groove or button on the side of the key, press or pry it gently to open the back cover. Take out the old battery, being careful not to touch the metal contacts inside to avoid short circuits. Use a CR2032 battery for replacement, and make sure the positive side faces outward when inserting it—it won't work if placed the wrong way. Snap the cover back on tightly and press the buttons a few times to test if they're responsive. The whole process takes just a few minutes, saving you the cost and hassle of going to a repair shop. Key batteries typically need replacement every one to two years; if the buttons become unresponsive, it's time to check to avoid being unable to lock the door while driving. Keep a spare battery at home so you can handle it anytime.
