How do you reset anti theft on Ford Taurus?

To reset the anti-theft system on a Ford Taurus, you typically need to use the vehicle's key or key fob. First, insert the key into the ignition and turn it to the "On" position without starting the engine. Leave it in this position for about 10 minutes until the security light on the dashboard turns off. Then, turn the key back to the "Off" position and try starting the vehicle. If this does not work, consult the owner's manual or a dealership for specific procedures related to your model year.
