2002 Impala passlock / security light problem

Is there a known repair for the security light/passlock problem that causes Impala and other GM products not to start for 10 to 30 minutes? If it's replacing the BCM at $500 that's fine, I just want to know that it will work. Thanks.

Does this have the PASSkey ignition system, with the little resistor button in the key, or does it have an RF chip in the head of the key which you can't see?

I wouldn't look at the BCM with passlock  it could be a ignition issue or a the passlock cotrol module your gonna need a scan tool or you need to find the electrical values and ohm them out

I had the same problem with my impala and what i did was go in though the radio in the settings area and reset the FOB and the car started fine but i did have to get a new ignition put in the car not the BCM
