Mercedes-Benz CLK320 ignition key will not turn, windows rolling down issue on Mercedes-Benz CLK320

Some Mercedes-Benz CLK320 owners report experiencing issues with the ignition key not turning, which may be attributed to a binding steering column, ignition switch problems, or issues with the ignition key itself. Additionally, if the key is not recognized when inserted, it could indicate a faulty key that requires replacement at a Mercedes-Benz dealer. Some owners have also encountered unexpected window rolling down problems, which can sometimes be resolved by following a specific troubleshooting method involving the window buttons and ignition sequence. In cases where the car fails to start, a recommended approach includes turning the key off, pressing the brake pedal, shifting to neutral, and then attempting to start the vehicle. If these methods do not resolve the issues, it is advisable for owners to consult a professional mechanic or contact a Mercedes-Benz dealership for further assistance.
