Question about 2002 Pontiac Grand Prix
A number of things simple to check. First turn on your headlights. Try and start the car. If the headlights dim or go out, then it is the battery or battery connections. Jump starting should work and then get it to a shop to check the battery and charging system. If they stay bright and you don't hear any clicking, could be the starter, neutral safety switch, or possibly a starting relay. To check the NSS, try and start in N. Assuming it is an automatic transmission. Let me know how you make out.

On many cars, if the battery is dead, it locks the key in the ignition. Put a battery charger on the car or replace the battery and give it a shot.

It is the security chips in the keys. Has this car been wrecked? Was this car made in Mexico? GM had the bright Idea of creating a security system that would do exactly this, I know on cars made in Mexico (like the HHR) You can reset the power and get the key back out, but vehicle will have to be reprogrammed with the master key. This involves turning the key from off to run position without ever going past run (i.e. start position) leave key in this position for 30 minutes. Turn key back to off for 30 seconds then back to run for 30 minutes. repeat this step three times. the last time, after 3rd 30 minute period, turn key off for 30 seconds and then try to crank. Please note this only works if the original master key is being used. You can then reprogram the second key following a similar sequence, only master key that is working has to be inserted to let alarm system know that vehicle is not being stolen only that you are trying to reprogram a key. If original master key is not being used then vehicle has to be taken to the GM dealership to program keys and possible key module replacement.

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.
