Question about Chevrolet Cobalt
Make sure the part where you insert the key is turned all the way to the off position, if this is not lined up correctly it may keep you from inserting the key - just a guess but may be worth looking in to.

You will have to have the ignition cylinder replaced in the car. The only thing that keeps that ignition from turning is a little tang on the sdie of it. The only way that tang moves is by the tumblers inside the cylinder moving it. They will have a hard time replacing it too as they can't remove the cylinder from the bore until it is in the "run" position. Obviously there are ways to get them out but it usually involves using half the tools of a good tech's toolbox. if it is towed the towtruck driver will have to use dolly wheels or remove the shifter cable at the transmission to get it to move as it will be stuck in park- unless is a standard shift.
I am sorry for the bad news. Get a second opinion from somebody that can put their hands on it , but it sounds like you have a tried all or most of the tricks.

SOURCE: Ignition Lock
I have/had the exact same problem today. I tried the solution as posted, spray WD40 into the ignition switch. That didn't work. I then tried rocking the car back and forth (front to back). That worked. My guess is the key is worn. I will eventually need a new ignition switch. But until that time comes, I will keep rockin' the car.

I had a similar problem on a 2001 GM product. The problems all stemmed from a worn out key. Keys are made from softer metals so that they wear out before the expensive cylinder does. Debris had collected in the cylinder preventing ANY key from turning it - corrected that with compressed air. Replaced the key at the dealer by providing the VIN and my ID w/registration - $10.00. Kept the old keys because they still worked for opening the trunk. Try it, I bet your symptoms and fix actions are very similar, at least, I hope so. Regards.

SOURCE: key wont turn in ignition
had the same problem with a 99 dodge van. tow truck driver put the key into the ignition and tapped it a couple of times while turning the key to freed it up and start the engine. works as long as you leave the key in the ignition so i use a second key to lock/unlock the van. hope this works for you. gary

Not the igniton switch, its the ingition cylinder and or the housing. The switch is not part of what you are really turning. It's connected to it via gears. The common problem is the key gets worn out and the tumblers wear also. Eventualy they do not line up right and will not make the "bar" drop in the cylinder to allow it to turn from the off positon. If you have the title in your name and the key has never been rekeyed or the code has been changed you can go down to a dealership with all of the info for the truck and they can cut you a key from the vin number. You can try that first before you put a cylinder and housing in it.
