2003 Pontiac Security Light

[mwilliamson006]

In need of some advice here. I have a 2003 Pontiac Montana Luxury Extended van. ( I have all the features.Dual sliding doors, backup sensors, etc...) The other day I locked my keys in the van. I called onstar and they tried to unlock my van. He said that it wasn't able to communicate. He sent the unlock signal several times. I was in the middle of town, so not out of range. Ever since my security light has been flashing when I open any doors, until I crank my car. I'm not having any trouble cranking. Any idea's? When I lock my van with the fob the lights flash to show that it's on, but the light is flashing very rapidly. Any Idea's???? Did onstar make my vehicle think it was being stollen? I had no troubles until after that day.

I would contact Onstar, there are a number of programable features in the antitheft system which they may have changed. The owners manual explains the features.

I looked in the manual. It didn't mention any onstar features.

Not Onstar features, Theft Deterrent features that Onstar may have inadvertently changed.
