GM (Chevy Colorado '05) Passlock
I finally figured out what is going on with my low mileage 2005 Chevy Colorado pickup. It is a very basic model, manual everything, including door locks and window cranks. Still it has a "security" system called Passlock. This somehow gets signals from the mechanical door lock and key operation (it seems) but I can not see any wires running form the door to the body and only one button, for the dome light, that signals the position of the door. So I wonder.
Problem, increasingly I get a red icon (padlock and car) which indicates the Passlock has been violated. The immediate problem is the starter will not function normally. When I turn the key to start nothing happens, but when I release the key the starter cranks, and thankfully disengages when the engine starts. To this I say "so what - spend $350 at the dealer's shop to fix? -ell no". Then things get worse. Now when the Icon is lighted and I turn the key and release it nothing happens, but on the second try (this is repeatable) the starter cranks when the key is released. It worked this way for several start/stop cycles. But now the engine will not continue to run, seems the ignition is shut off somehow by the Passlock when the starter is disengaged.
Looking on the web I see there is a whole business out there selling ways to defeat the GM Passlock, I am not ALONE!
Any advice on how to work around the GM Passlock without buying the "magic tool"... seems to be available for under $40, but I don't know if it really works, so testimony on how the defeat tool works would also be helpful.
This 2005 Chevy was the first USA manufactured car I have purchased in 25 years, the last was a 1980 Pontiac Sunbird (and those of you old enough to remember that car know why I went to Japan for my next car). Well, given I have only 10,000 miles on the Colorado, but its warranty is expired on time basis, and this is the third problem needing dealer attention, it may be another 25 years before I buy another USA car... not that I expect to live that long.
