i have m-benz e220 .problem is that key in turning in the ignition while ignition won't on and stering also locked

If the switch makes no noise when you insert the key, but the head lights go on and the radio works, the ignition switch module has probably failed and will need to be replaced

My 2006 Mercedes key will not turn are lock are unlock doors it does nothing I drove and g Went to drive again it wouldn't do anything I have changed the fob battery still. Nothing
