I HAVE BEEN IN MOBILE ELECTRONICS SINCE 1982,AND THIS GM VATS/PASSLOCK IS A JOKE.WORST DESIGN EVER.
I HAVE A 2000 TAHOE THAT I HAVE A REMOTE START ON AND IT WORKS PERFECTLY,THE PROBLEM IVE HAD IS USING THE KEY,SOMETIMES IT WILL START SOMETIMES NOT.SOME OF MY BEST FRIENDS WORK FOR GM DEALERSHIPS AND HAVE TOLD ME HORROR STORIES OF THESE SYSTEMS OVER THE PAST DECADE.ONE SAYS THEORETICALLY BYPASSING THE SIGNAL WIRE SHOULDNT WORK, THE COMPUTER REFERENCES VOLTAGE AND THE RESISTANCE SIGNAL?.I HAVE HAD THE GM QUICK FIX DONE AND THE WHOLE TRANSMITTER REPLACED AND STILL HAVE INTERMITTENT STARTING ISSUES,I JUST PERMANTLY BYPASSED MINE WITH A HARD RESISTOR (AND A TOGGLE SWITCH TO BYPASS MY BYPASS-IN CASE) SO WE WILL SEE HOW IT PANS OUT,ANYMORE WORD AND I WILL PASS IT ON....
