Locked up PCM

[97Normalneon]

Ok, I am looking for help to unlock a PCM in a 2000 Neon. I was helping a friend of mine with his car that was in a front end wreck. The front end is all fixed, but the original computer was cracked and would cut out. I found a used computer and installed it and the car would start, run for 5 seconds, and then die 4 times. Now the car won't start at all with the replacement computer. For now the original computer will start and run the car but it is unreliaible with the original computer. I did find a TSB (08-030-06) on ALLDATA.com that says that the Theft Deterent System locked up the car, because the VIN was wrong in the replacement computer. SO I need to find a scan tool, or someone that can help me unlock this computer here in south eastern Michigan.

OK here is what I know after talking to the dealer. Because the car has vehicle theft system from the factory, I locked up the computer because the VIN's were different between the two PCMs. The only way to fix this is to buy a new computer. The dealer said that you can't overwrite the VIN in the new computer. So be careful if you have to replace the computer on you car.
