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

Doing roadside assistance I have ran into this problem several times and if you look in your owners manual it will tell you how to reset it. Some of the cars you have to wait up to 10 min. with the key in the ignition and try again. The light will go out. READ carefully our owners manual.
Hope this helped....Kevin

With the doors shut, insert the key into the drivers door lock. Lock and unlock the door 5 times. This should reset the system. If that doesn't work you should contact a qualified repair shop.

My 2000 cavalier has done this for 6 months. You take your key out then open your door, wait ten minutes and the system resets itself and the car will start-annoying you bet!!!

Try re-setting the computer...Disconnect the negative terminal of the battery and leave off for 5-10 minutes. This will allow the computer to reset. The charger may have interupted the signal or something.
