Pontiac Repair: Montana Anti Theft Curse, security message, bcm

Question
Hi need some help with my anti theft. It turned on the other day while i was rounding a corner. How do i reset it, get rid of it, turn it off? Any ideas? The van still starts and runs but the security message is coming up in the message center and the radio will not come on.
Thank You
Ami

Answer
Hi
Not knowing the EXACT year I cannot look up the schematic, however, with the problems your experiencing, I would recommend taking it to your local repair shop that can scan the BCM and retrieve codes. It will have codes stored in memory.
From there you can either post back for my help or have them diagnose the codes there.
I hope this helps
Good Luck
