My key would not turn in my ignition switch so I went to advance and bought an ignition switch and replaced the old one. Now the switch turns fine and starts the car. It runs @ 5 seconds and the car shuts off. I have been informed that I have to take the old key and the new key to the FORD dealership and they have to program the new key???? Then the car will stay running. This sounds like a crock to me. I don't see a chip in the key. Is this correct information or has the mechanic screwed something up????
