2 Answers
Mercedes-Benz C200 key battery replacement method is as follows: 1. Push the small switch with teeth on the tail of the remote to the right; 2. Gently insert the key into the slightly larger hole at the rear of the key slot, insert about one centimeter until you touch a latch for the remote battery cover, then gently pry it open; 3. Open the cover by hand to reveal the remote's battery; 4. Remove the old battery, replace it with a new one, close the key cover, and reinsert the manual key. The Mercedes-Benz C200 has a body length of 4686mm, a height of 1810mm, a width of 1442mm, and a wheelbase of 2840mm. It is equipped with a 1.5T engine and a 9-speed automatic manual transmission, with a maximum power output at 5700 rpm and a maximum torque of 250 Nm, featuring a turbocharged intake system.
I just replaced the battery for my Mercedes-Benz C200 key myself, quite convenient. Take out the key, find the small button on the side, press it to open the back cover, and you'll see a common CR2032 coin cell inside. Gently remove the old battery, being careful not to dirty the metal contacts, then insert the new battery with the side printed with the model number facing up to ensure correct positive terminal alignment. Close the cover and test the lock/unlock functions. If response slows or delays occur, it might signal battery aging - replacing it solves the issue. I recommend Panasonic or Samsung brands for better durability, avoiding cheap ones prone to leakage. Keep the key away from damp places or heavy pressure, maintaining cleanliness. Check battery status every two years to extend key lifespan and avoid garage visits. The whole process takes just five minutes, beginner-friendly too.
