Key repaired, still won't sync.

I hooked up the durametric a couple months ago and was code free. Will need to check again. I knew this was an issue when I purchased the car. The previous owner had taken it to the dealership and spent $700 on "something in the doors." No repair invoice to check what was done. My first new car was a 1977 Toyota Celica Liftback. Waited 3 months and paid full sticker to get a black one. Still my favorite car color.
