• EIS (Electronic Ignition Switch) Failure: Sometimes, the problem isn’t the key but the module inside the dashboard. If the key will not turn or the guiding lock will not launch, the EIS might be defective.
• Infrared Window Damage: The little clear window at the suggestion of the key must be clean and scratch-free to interact with the car.

5. How to Replace a Mercedes-Benz Key
