The battery model for the Mercedes-Benz C-Class remote key is CR2032. Replacing the battery: Take the Mercedes remote key, face the back of the key toward yourself, press the small button at the bottom while simultaneously pushing the back cover upward to remove it. Pull out the battery holder from the left side of the remote key, remove the old button battery, and replace it with a new CR2032 button battery. Reinsert the battery holder and reattach the back cover as it was. Mercedes-Benz C-Class: It is the best-selling model and also the most comprehensive lineup among all Mercedes-Benz series. The new C-Class sedan is equipped with an active safety system, intelligent lighting system, preventive safety system, passenger safety protection system, and rescue tools, making it comfortable, refined, practical, and top-tier in safety. The C-Class sedan can take several measures based on the type and severity of an accident: automatically shutting off the engine, cutting off the fuel supply. Hazard warning lights and emergency interior lights are activated automatically, and if necessary, the side windows are partially lowered, and the doors are automatically unlocked.
I had a sudden key fob failure while driving my Mercedes-Benz C-Class. After some struggle and opening it up, I found the CR2025 battery was dead. That was really stressful – couldn’t unlock the car parked at the mall entrance. Luckily, I bought a new CR2025 battery at a nearby supermarket for just a few bucks and fixed it. Don’t underestimate this little thing; it typically lasts 2-3 years before draining. A slowing red LED blink on the key indicates low battery. Since then, I’ve made it a habit to keep a spare battery in my bag for quick replacement, avoiding expensive dealership service with 30-minute waits. DIY replacement is easy – just pry open the key’s back cover with a rigid card. But be careful not to reverse the battery polarity, as it may damage the circuit board.
