my anti theft light is blinking

This would depend on if car will crank and run.

Anti theft blinking car no crank no run

Try this,remove key from car,remove positive cable for about ten minutes,then place key in car and turn to the on position,then replace battery cable,should reset,but if not you may have to take it to dealer to reset it,

did that no help

Won't start

You disconnect the negative side of the battery wait 10 minutes then start the car I think this is just a temporary start

My friend just had this happen. Her anti theft light was the only thing blinking and the car would not struggle to turn over or even could hear the starter tap. So naturally, I was determined that it was her theft system and couldn't possibly be that bad of a battery bc of not hearing the starter at all. So even after talking to Autozone and the Ford dealer about her 07 Fusion.....it ended up being the battery. If the battery had been dead and NOTHING else would come on...then why would that damn theft light be able to be blinking ? It makes no sense!! Someone make it make sense??

How can I take the anti-theft of my car

The battery can cause this if its weak and doesn't deliver proper voltage, Antitheft can be very sensitive to voltage
