This is a rather generic post and problem. I(and many other 2000-05 gm owners) Have an issue with the security light or the passlock not allowing the car to start. Little back story, I had the same problem about 6 months ago and I removed the passlock interface/module and the problem went away more or less. So forward six months it's back and I generally have to do the soft reset on the security system to get it to start. (Leave key in on position for ten minutes) Sadly this no longer works and I have a two ton paperweight. So I just went and got a new ingition cylinder with a security chip and installed it and I put the passlock module back in. I tried to get it to relearn the new code and no luck. Since it's so cold, I was in a hurry and COMPLETELY forgot to disconnect the battery for a bit to remove the old error codes and all that jazz. I'm gonna give it another shot when i warm up. If I disconect the battery and redo the "learning new code" process think it will work? And if this does not work, what should i try next? Replacing the ignition switch? Any ideas would be so very much appreciated, thanks guys!
