2 Answers
To replace the key battery for the new Mercedes-Benz CLC230, follow these steps: 1. There is a button on the back of the key. Press this button and slide the back cover of the key forward to open it. The battery is located in the slot nearby. 2. During the replacement process, be sure to note the battery model. Most Mercedes-Benz key batteries use the 3V-CR2025 model. After removing the old battery from the slot, replace it with a new one. 3. Next, reattach the back cover of the key. Once installed, the battery replacement is complete. The lifespan of a Mercedes-Benz key battery is typically two years, while the original factory battery can last up to six years. When the key battery is low, the Mercedes-Benz vehicle will provide two types of alerts: one is when you press the ignition switch, the dashboard will display a message to replace the key battery. The second is when you press the lock or unlock button on the key, the indicator light on the key will dim or fail to light up, indicating that it's time to replace the key battery.
I've been driving the new Mercedes-Benz CLC230 for a while and have replaced the key battery several times. Opening the key casing is quite simple - use a small screwdriver or plastic pry tool to gently pry open from the gap on the back of the key. Don't apply too much force, as you might damage the internal chip. When removing the old battery, remember its orientation. The new battery should be CR2032 type, available at supermarkets or auto parts stores. After replacement, close the casing and test the remote's response speed by pressing the buttons. As a related point, key batteries typically last about two years. If the car sits unused for long periods, it's advisable to keep a spare battery at home. I also regularly clean dust from the key's crevices to prevent button sticking - these small maintenance habits can save a lot of trouble.
