The method for replacing the key battery of the Mercedes-Benz CLA180 is: 1. Pull up the key to release the buckle; 2. Pull out the key; 3. Insert the key to pop open the back cover for replacement. The Mercedes-Benz CLA180 is a compact sedan with body dimensions of 4645mm in length, 1777mm in width, and 1413mm in height, and a wheelbase of 2699mm. The front suspension of the Mercedes-Benz CLA180 is a MacPherson independent suspension, and the rear suspension is a multi-link independent suspension.

I've been driving a Mercedes-Benz CLA180 for several years, and replacing the key battery isn't difficult—it only takes a few steps. First, you'll need to prepare a CR2032 coin cell battery, which is easy to purchase. Use a small tool, like a coin or a thin plastic card, to gently pry open the back cover of the key, being careful not to apply too much force to avoid damaging the casing. Once open, you'll see the battery compartment. Carefully remove the old battery, taking care not to touch the internal circuitry to prevent short-circuiting. Insert the new battery with the positive side facing up to ensure proper alignment, then press the back cover until you hear a click to lock it in place. After replacement, remember to press the key buttons to test if the light turns on. It's a good practice to check the battery life every six months to avoid sudden power loss when locking the car. Typically, the key battery lasts one to two years. Frequent battery drain might be due to improper storage, such as exposure to moisture or high temperatures. In short, doing it yourself saves time and hassle—just take it step by step for a smooth process.
I once helped a friend replace the battery in their Mercedes-Benz CLA180 key, and the process was effortless, almost as fun as playing a game. All you need is a small flathead screwdriver or a keychain tool to gently pry open the key by aligning it with the groove on the back—no professional equipment required. Inside, you'll find a coin-shaped CR2032 battery. Simply remove the old one, insert the new battery with the positive side up as marked, and ensure the contacts are clean and free of dust. When reassembling, press the cover firmly and test the lock/unlock functions to confirm they work properly. This DIY battery replacement takes less than five minutes and saves you the hassle and expense of visiting the dealership. Additionally, it's a good idea to keep two spare batteries of the same model in your car for emergencies while traveling—online tutorial videos on your phone can make the process even easier. Signs of a low battery include reduced remote range or delayed response, so addressing it promptly can prevent awkward situations.
