I have a 1993 300 CE . Today my key won't turn in the ignition. Tried moving the steering wheel, gear shift, won't turn. I tried the courtesy key and the master key for making duplicates and they both work. Car did die after starting and I had to let it warm up. Has 295,000.00 miles. Is this a problem with the key or is my ignition going bad?. Any advice would be appreciated. Thanks
