Using the Physical Key

Expert Insight: “Always keep the mechanical key in a safe and accessible location, separate from your key fob,” advises John Miller, a seasoned automotive electrician. “This ensures you have a backup plan to access your vehicle in case of emergencies.”

  • Check the Battery: It seems obvious, but ensure the battery is correctly installed and not depleted. Replace it if necessary.
  • Reprogram the Key Fob: In some cases, you may need to reprogram your key fob to sync it with your Mercedes. Refer to your owner’s manual for instructions on reprogramming.
  • Consult a Professional: If you’re unable to resolve the issue yourself, it’s always best to consult a qualified automotive locksmith or your Mercedes dealership for assistance.
