2002 Chevrolet Silverado 3500 Q&A

2002 Chevrolet Silverado 3500 Question: My SECURITY light flashes when I open the door and I can't program a new remote.

I have a 2002 Silverado 3500 that has a blinking SECURITY light that comes on in the MESSAGE CENTER when I turn off the vehicle and open the door. Yesterday I tried buying a pair of OEM key FOBs, as mine didn't have any when I bought it from the guy a month ago, and during the programming process where you are supposed to hold down the vehicle UNLOCK button while cycling the ignition on and off twice, then let go of the switch and it is supposed to lock and unlock itself, thereby indicating that the truck is in "learn" mode, nothing happened. After I cycle the ignition twice and let off of the UNLOCK button, nothing happens. Therefore I am unable to program the key FOBs...Please help. -
