Sitting here laughing about this because my 2002 Impala, bought new in 2002, 3.4L engine, now has 223.6k miles on it, and for years now whenever I stick the key in the ignition I always have to kind of wiggle, jiggle, and shake the key to start the car.
So this is what I'm headed for? Pulling the ignition block out and cleaning it?
Then I'll probably get the SECURITY message back again - which I haven't seen for about 7 years now ... despite doing NOTHING to fix it!
