Question about 2008 Pontiac Grand Prix
Wait for 1 minute. If light still doesn't go out then it is either a bad door latch or possible body control module(bcm)
Sometimes if you unplug the bcm and wait a minute and plug it back in it may work again. Sometimes they lock up.
Body Control Module Replacement Removal Procedure
Notice: Electrostatic discharge (ESD) can damage many solid-state electrical components. ESD susceptible components may or may not be labeled with the ESD symbol. Handle all electrical components carefully. Use the following precautions in order to avoid ESD damage: • Touch a metal ground point in order to remove your body's static charge before servicing any electronic component; especially after sliding across the vehicle seat. • Do not touch exposed terminals. Terminals may connect to circuits susceptible the ESD damage. • Do not allow tools to contact exposed terminals when servicing connectors. • Do not remove components from their protective packaging until required to do so. • Avoid the following actions unless required by the diagnostic procedure: - Jumpering or grounding of the components or connectors. - Connecting test equipment probes to components or connectors. Connect the ground lead first when using test probes. • Ground the protective packaging of any component before opening. Do not rest solid-state components on metal workbenches, or on top of TVs, radios, or other electrical devices.
Important: You must perform the new body control module (BCM) setup when replacing the BCM. Refer to Control Module References .

HI, I'm reading your problem,
Let me explain something about your car.
2005 Ford Taurus, The key on that car has Chip inside of the key and receiver on the ignition switch,
Check if the key you are trying to use is Black and has a plastic head.
If not you need a key with that characteristics.
But if you have the right key, Remenber if you had drop on the floor, or hit with something,
Because some times they come damaged, with insignificat thins.
Remenber if you left the key close to a magnets like speakers.
If nothing aply at your case, you need to call a place Aloha Smith, they have the computer to program or reprogarm your key. IF not you can't start your car.
OK.. I hope this information work for you.
Thank's for submit yous question on fixya.com

This is most likely a problem with your Passlock anti-theft system which is known issue with these cars. Passlock is a "passive" anti-theft system, which means that it will disable your ability to start the car if it thinks there is a problem. The three components that can cause this are: 1) Ignition Switch, 2) Ignition Cylinder, 3) Body Control Module (computer). The dealer is the only one who can solve this problem (unless you can bypass it, but it is not that easy). Estimated repair from most dealers is $800 and up.
