Same problem with key. Mech. thought it was the starter but even with a new one no starting at all. They tried to re-program but no positive results at all. Put it in neurtal and started once but would not start after. My Security light was on for about 8 months prior but no problem starting the car at that time. Security light turned off for about 3 weeks before this so I thought it was OK-reset.
the car would not start do to anti-theft system. I cleaned the key tried again and it started. this has happenthree times since I have owned the car.

Have had this issue for a couple years now. Occurs sporadically seemingly at its own whim and always at the worst possible times (when I was being followed by someone after a late night grocery run). I've even had a duplicate key made thinking there might be an issue with surface contact/conduction but the problem still continues to this day(07-17-15)!

My brother locked his keys inside his running car. A friend of his tried his own Buick key in the door and the engine quit running just as he put the key into the keyhole; also now it won't start.
For a long while the engine would just stop (while driving down the road or at park/idle). I could (when driving) pop it in neutral start it and keep going. It has had the crank sensor replaced. ...
