Hi there. It sounds like you either have a worn key or worn key cylinder. Have a new key cut and see if the new key turns the cylinder to start the car. If that does not work, then the cylinder may be worn and in need of replacement. I would have a qualified technician perform an inspection to avoid replacing unnecessary parts. YourMechanic has several available technicians that can assist you with a key does not turn inspection.
