Thanks folks, most especially Ray Corri and Poncho. I read EVERY SINGLE POST on this thread before tackling the task at hand, resistorizing my '01 Grand AM passlock. Thanks for all the helpful advice, took about an hour including a trip to Radio Shack for resistors. The car started with the first turn of the key and the SECURITY light is off. Couldn't be happier!
Advice to everyone: Don't hesitate, spend an hour and solder in the resistors. It's not hard, JUST DO IT.
