Well guess what happened? Chevy had the Blazer for 2 days and said it was the pass code sensor. I paid $480 and went to start it and the same damn thing happened right there on the lot. They insisted it must be a defective pass code sensor and put in another one. It's worked the last few weeks until today, same CRAP! They do'nt want to listen to me about this tech bulletin and are trying to tell me some more BS! Any suggestions?
