How to Start a Mercedes-Benz When the Key Fob Battery Dies?

Mercedes-Benz key fob battery dead startup method: Place the remote key on the induction key position, then press the start button. Mercedes-Benz vehicles have a dedicated induction key position on the steering column below the steering wheel. If the car's remote key runs out of battery, vehicles equipped with a one-touch start system can be started this way. Mercedes-Benz is a German luxury automobile manufacturer with a comprehensive range of models, currently mainly producing C-Class (mid-range sedans and sports cars), E-Class (high-end sedans and sports cars), S-Class (luxury sedans and sports cars), and G-Class (SUV off-road vehicles). The Mercedes-Benz logo is a three-pointed star, symbolizing the mechanization and integration of land, water, and air.
Last time after camping, the Mercedes key suddenly stopped working. Actually, you can do this: first, take out the mechanical key blade from the key fob. There's a small cover on the driver's side door handle—pry it open to lock or unlock the car. Once inside, don't panic. Place the key against the bottom of the center console cup holder or the key symbol on the right side of the steering wheel. Mercedes'感应 system will recognize it. Press the start button while holding the brake, but note that only basic functions will work—the air conditioning might not operate. Quickly go to a convenience store to buy a CR2032 button battery and replace it yourself. Be careful not to lose the waterproof gasket on the key's back cover. I encountered this situation in the wild before and fixed it in half an hour.
As a veteran auto technician, here's a reminder: All Mercedes-Benz vehicles with keyless start have emergency solutions. When the key fob battery dies, first locate the hidden keyhole on the door handle - this design is particularly thoughtful. After entering the vehicle, focus on finding three induction zones: the center console compartment groove, the lightning symbol on the right side of the steering column, or simply press the key directly against the start/stop button. Keep the key in position for about 15 seconds until the dashboard displays a green key icon, then you can start the engine. Remember to check that replacement batteries are specifically 3V - installing them backwards can fry the chip, which makes this procedure much more precise than changing batteries in regular cars.
