Your Pontiac has a Transponder Key which has to be Programmed
It is best to have Dealer or Shop connect a Scan Tool & Program, but you can Program the New Key ONLY if you have a working Key that will start the vehicle
IF NOT, GM Dealer or Shop with proper Scan Tool will need to Program
Some Mobile Locksmiths can Program also

Turn OFF the ignition, and wait 5 seconds .
Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes .
With a master PASS-Key III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
