HOW TO DEACTIVATE OR RESET ANTI THEFT? CAR

1999 Ford Taurus

Electrical problem
1999 Ford Taurus 6 cyl Front Wheel Drive Automatic 127000 miles

The keyless entry wouldn't work and our son used his key to unlock the door and now the car won't start and the anti theft light keeps flashing. He is at college and a few guys tried to help by disconnecting battery and then they also tried turning key on waiting 20 min. But still nothing! Any suggestions?

You can't disable the theft light. The key to start the car has a electronic chip in it. If a programmed key isn't used to start up the car, it won't start. Check any other keys you have for the car. You may be using an unprogrammed key or the chip in it went bad. If you go to the dealer to get the key re-programmed you will probably need all the keys with you in the event they have to totally reset the anti-theft system and re-program the keys. It's usually around $75.00.
