New Mercedes-Benz C180 Supercharged Version key battery replacement method: First, locate the sliding switch on the car key, slide to open the mechanical key. After pulling out the mechanical key, you can see the inside of the car key. Use the just removed metal key to pry open the key cover, and you will see the battery. Remove the battery, insert the new battery, and then close the key cover. The Mercedes-Benz C180 is a C-Class model launched by Mercedes-Benz. The car has a length, width, and height of 4784mm, 1810mm, and 1457mm respectively, with a wheelbase of 2920mm. In terms of appearance, the styling of this car has not changed much, mainly involving the front bumper, LED daytime running lights, and new rims. Inside the car, the main change is the addition of chrome decoration on the glove box handle.
As the owner of this car, I've changed the battery myself when the key ran out of power, and found it quite simple. The Mercedes-Benz C180 smart key usually has a small gap at the bottom or side. Use a thin plastic tool like a fingernail or the corner of a credit card to gently pry open the shell. Inside, you'll see a small button battery, model CR2032, which is commonly available in supermarkets or online for about three yuan each. Gently remove the old battery and replace it with the new one, making sure the positive side is facing up to avoid reversing it. Then, align and press the key shell back into place. The whole process takes less than five minutes, saving you the hassle and expense of going to a 4S shop. A related reminder: if the key doesn't respond after replacement, don't panic—it might just need re-pairing. Try restarting the car or refer to the vehicle manual for pairing steps. Also, avoid leaving the key in high-temperature places like under direct sunlight to prolong battery life, which typically lasts two to three years. Be careful not to damage the plastic when prying, and wearing glasses for better visibility can make the process safer.
As someone who often helps friends with car repairs, I've replaced quite a few Mercedes key batteries, and the procedure is the same for the C180 model. Look for a small slot on the key, gently pry it open with a coin or small screwdriver, and you'll find a CR2032 battery type inside, which is easy to recognize. Simply remove the old battery and replace it with a new one, ensuring the positive and negative terminals are correctly installed, then close the casing and test it. For added reliability, it's advisable to choose well-known brands like Energizer batteries, which have good heat resistance. If the key doesn't work properly after replacement, check the vehicle settings to see if it needs resynchronization—usually pressing the key button a few times will activate it. Related knowledge: The lifespan of the key battery varies depending on the frequency of button presses; less frequent use means longer battery life, and avoid exposing it to moisture frequently. Maintenance tip: Regularly clean the key casing to prevent dust accumulation on the internal contacts.
From personal experience, changing the battery in a Mercedes key isn't as difficult as imagined, even for the C180 model. When doing it, lay the key flat on a table, use a thin tool like a toothpick or blade to gently pry open the clip and remove the cover to access the battery slot. Replace it with a new CR2032 battery, then reassemble. Handle with care during the process to avoid scratching the surface. After completion, test the functions to ensure they work properly; if not, check the battery orientation or the car's battery status. A reminder: avoid operating in rainy conditions to prevent short-circuit risks. The batteries are very cheap; you can buy a bunch online for just a few bucks to keep as spares.
