HI,
I am very sorry that you have not been helped yet. I just came online and saw your question
Hopefully you have it by now. But if not, this is what you need to do:
disconnect the negative battery cable. Now insert the key into the ignition and turn to the on position and have driver door open. After at least 60 seconds, reconnect the negative cable to the battery(with key still in on position).
The alarm will sound for 60 seconds and then stop. At that point, cycle the key off, then crank it. It should crank now
