Method for replacing the battery in a Mercedes-Benz C180 key: First, locate the sliding switch on the car key, slide it to open the mechanical key. After pulling out the mechanical key, you can see the inside of the car key. Use the metal key you just pulled out to pry open the key cover, and you will see the battery. Remove the old battery, insert the new one, and then close the key cover. The Mercedes-Benz C180 is a C-class model launched by Beijing Benz. The car's dimensions are 4784mm in length, 1810mm in width, and 1457mm in height, 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 wheel rims. Inside the car, the main change is the addition of chrome decoration to the glove box handle section.
Last time I helped my neighbor replace the battery in their Mercedes-Benz C180 key, it was easily done with a coin. First, locate the small notch on the back of the key, wedge the coin in and give it a gentle twist to pop open the back cover. The silver coin battery inside is a CR2025 model—make sure to note the orientation of the old battery (positive side up) before removing it. When inserting the new battery, be careful not to put it in backwards, or the buttons won't work. You'll know the cover is securely fastened when you hear a click. The whole process takes about five minutes and doesn’t require a screwdriver—just remember to buy Panasonic or Sony batteries for longer life. After replacing it, immediately test the response by pressing the unlock button. Before the battery dies, the remote control range will noticeably shorten.
