I am sorry that you have not been helped yet. I just came online and saw your question.
Ok, open driver door and leave open. Disconnect the negative battery cable and then insert the ignition switch and turn ignition to on position. Wait at least 60 seconds and then reconnect the battery cable. The alarm should sound for about 60 seconds then go off. At that point cycle key to off position, wait 5 seconds and then crank engine
That should reset and turn off the alarm from happening again
That was the only method I know of. I will opt out and see if another expert knows another method
