The battery replacement tutorial for the old Mercedes-Benz CL180 key is: 1. There is a small switch in the upper middle part of the back of the key. Gently press it to remove the mechanical key; 2. Press the button to open the back cover; 3. Open the battery compartment on the left side of the key to see the battery; 4. Use a small flat-head screwdriver to remove the depleted battery; 5. When installing the new battery, ensure the positive pole faces upward; 6. After installing the battery, reassemble the key. The dimensions of the old Mercedes-Benz CL180 are 4581mm in length, 1770mm in width, and 1448mm in height, with a wheelbase of 2760mm and a curb weight of 1545kg.
When I used to drive the older Mercedes CL180, I changed the key battery myself, which was quite simple. The battery model is usually a CR2032 coin cell, available at any hardware store. I prepared a small flat-head screwdriver or a coin to gently pry open the shell from the edge gap, being careful not to use too much force to avoid scratching the internal chip. After removing the old battery, I carefully checked the positive and negative markings—the new battery must be inserted with the positive side facing up. Then, aligning the shell clips, I pressed it back into place gently until I heard a click, indicating it was securely fastened. Finally, I tested it by pressing the unlock button to see if the vehicle responded. If it didn’t work, the battery might have been inserted backward or there could be another issue with the key, in which case it’s best to visit a professional repair shop for inspection. Regularly replacing the battery can prevent failures at critical moments, saving you from unnecessary stress.
