Try pulling the fuse for the anti theft system and starting. If the car starts normally, then the problem is with the theft system. The theft system will reset itself after a period of time.

yes the fast blinking theft light indicates that theft mode is activated. you wont be able to start the vehicle until you have the keys reprogrammed at your local ford dealer.

your anti theft is more than likely doing it is their a key pad where you enter a code? If so you need to enter the code that was hard wired to it when you have a bad battery or change the battery the system defalts to the hard wired code, if you don't know the code it should be on a sticker in the trunk I think it is on the hindge to the trunk lid right side!

NEED TO RUN THEFT CODE CHECK TO VERIFY WHAT PART OF THEFT SYSTEM IS FAILING .COULD BE JUST KEY ,IGNITION SWITCH OR AN ELECTRICAL PART

dealer only ,,,2005 encrypted software and you cannot by pass it

Either you may be using a key that you had copied from the original or your chip went bad in your original key. Most of cars now a days have the key censor in the key so if it is the incorrect key it will not start your car or if it does not read that chip it will not start

The taurus is equipped with what is called a PATS (passive anti theft) that wont let the car start until it recognizes the key in the ignition, some things to check, first when you put the key in and turn the car to run (not start) does the theft light blink fast in the dash or is there a red on light on the dash that starts blinking? if so it is a PATS problem, the only ones I know of that can program keys are dealers, if the car wont turn over it probably is not a fuel pressure issue, the most common thing would be the PATS keys either unprogrammed or somthing wrong with the module. hope this helps

This is a long shot...I know but for what its worth....
The Taurus has in much the same lay-out as the European Ford (e.g the old Scorpio). You should find two large fuseboxes under the hood near to the windscreen (one each L/R). When driving in rain humidity enters these fuseboxes. This can give ANY funny combination of effects.My car started blinking with headlights, horn waking the entire block and a lot of other fenomenas allthough shut off and key out. Try taking out all fuses (map them on a sheet of paper) and enter some compressed air at short range into each and every fusecontact.
(Just in case ...if you have a towinghook with a connector...do the same with these contacts)

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.
