Common Mercedes Key Fob Issues

Troubleshooting Your Mercedes Key Fob
Before assuming your key fob needs professional repair, try these troubleshooting steps:
- Check the Battery: The most common culprit for a malfunctioning key fob is a dead battery. Replace the battery with a new one and test the key fob again.
