Method for replacing the battery in a Mercedes-Benz CLS280 key: 1. Pick up the Mercedes-Benz GLS280 remote and remove the protective case; 2. Hold the remote key, flip it to expose the back side, press the small square button at the bottom, and use your other hand to slide open the rear cover of the remote; 3. Remove the old battery and promptly replace it with a new button cell, then reinsert the battery holder into the remote; 4. Reattach the rear cover of the remote. The Mercedes-Benz CLS280 is an aesthetically pleasing vehicle from the Mercedes-Benz lineup, featuring a fastback design at the rear. In terms of body dimensions, the car measures 4996mm in length, 1881mm in width, and 1411mm in height. The Mercedes-Benz CLS280 is equipped with two types of engines: a low-power version of the 2.0-liter turbocharged engine and a high-power version of the 2.0-liter turbocharged engine.
I've changed the battery in my Mercedes CLS280 key several times, and it's pretty straightforward. There's usually a small notch or button on the key. You can gently pry open the casing with a fingernail or a coin—just don't use too much force, or it might crack. Inside, you'll find a small button battery, typically a CR2032. Remove the old one and replace it with a new battery, making sure the positive side is facing up; otherwise, the remote won't work. When reassembling, press the cover firmly to ensure the clips snap into place. After replacing, test the unlock and start functions by pressing the buttons a few times. If everything works, you're done. The whole process takes less than two minutes. Keeping spare CR2032 batteries in your car is practical, so you won't be caught off guard at a critical moment. Doing it yourself also saves the unnecessary cost of going to a shop. Newcomers will get the hang of it after a few tries.
As a DIY enthusiast, I find changing key batteries incredibly convenient. The Mercedes CLS280 key is cleverly designed—just pry open the edge cover to reveal the battery. I prefer using a small screwdriver for gentle operation to avoid scratches. After replacing the CR2032 battery, I clean the internal contacts to ensure strong signal transmission. When the remote starts weakening, it's time to check; these batteries typically last 1-2 years. Buying a pack of CR2032s in advance is super cost-effective. Always test the unlocking range immediately after replacement to confirm it's restored. Don't forget to recycle old batteries responsibly—it's eco-friendly. Such small tasks sharpen hands-on skills while saving significant money.
