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.
