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

Something in your anti theft system has failed. The key,transceiver, or module. The only way to find out is to run a diag on that circuit. You will need special tester.

Fords have a chip in the keys and a reader in the ignitions switch, when you insert the key and the theft light stays on solid then the key has passed. If the light flashes quickly then the key didn't pass the check and the vechicle will not start. This can some times be a key problem and some times a reader problem . But the keys can only be programed with a computer in this situation. The dealer or most lock smiths have these computers.

SOURCE: car will not start-battery is fine

Try this Put your key in turn it on dont start wait 10 mins remove key wait 10 seconds repeat this a total of 3 times. Your theft light should go out. As long as the light is on your fuel system is disabled. If that dont work try a different key do the same thing. If that dont work a dealer needs to probably replace and reprogram your ignition switch and keys

take the positive side of the battery off for about 3 seconds and then put it back on to see if this will reset the security code
