How do I reset the theft security on my car. on 2004 Pontiac Grand Prix

The battery ran down and when I recharged it the car has been acting funny. Had it checked at the parts store and it said it was the security system. I don't want to have to take it to the Pontiac dealership, please help.

your battery ran down. no issues with the alternator? try disconnect battery for a few minute. be sure to coat both posts with petroleum jelly before reconnect. another weird on was to disconnect engine light and reconnect. i don't know why that one worked but it does some times. still trying to figure that one out. if these fail then call dealership and ask them. information is free. talk to parts department.
