Am currently looking to replace my bad ignition lock on my car and stumbled into this almost year old thread.
I believe that the key you received with your new ignition lock was only a template key and will not start the car. You would need to have a key with the correct resistor pallet made using that template key that came with your new ignition lock cylinder.
Hopefully this will help anyone in the future having the same issue.
