2000 Pontiac Grand Prix 6 cyl Automatic 74000 miles

We have a 2000 Pontiac Grand Prix GTP Daytona 500 special edition
its a great car and we love it we've never had any problems until recently
on new years eve we were dropping a movie off and the car was perfectly fine. We went in and locked the door on the car too many times. When we came back out it would start and then die quickly. We think it has to do with the anti theft part of the alarm. It seems as if its just cutting the gas supply off. Any ideas?
we've tried reseting the key
we've tried holding the gas pedal
we've check the fuel pump
disconnected the battery
disconnected all wires and reconnected and it still starts and then dies right away.
weve also tried to reset the alarm with everything that the book says and still nothing
and the last thing we tried we read on the internet to start it and let it die then leave the key in for 10 mins and do that 3 times. And it still wont work.
also when it starts it starts perfectly and sounds great
so any ideas?
thanks

Try this procedure:

GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it

Yes it if has a chip in the key either a dealer or a locksmith can fix it. Be sure to bring proof of ownership with you.
