I have a 2002 ford explorer that will not start, the key does turn and the battery is new but the theft light is constantly blinking. what can i do

This just happened with my 1999 Ford Explorer which would not start intermittently. My mechanic did a bunch of stuff before he finally realized it was the anti-theft chip in my key that was old and no longer working. He had me bring in my spare key and suddenly the car worked fine. Because the old chip was not working, the car was not recognizing the key and the ant-theft system was kicking in and was disabling the engine. That is why the theft light is blinking when you try to start the car. Try your spare key and you may find everything is solved... and for no $$$!

If it is an aftermarket alarm u can just unplug the module (usually located under the dash). If it is stock alarm try looking for a bypass button below the steering column. If you find one push and hold while turning the key. If no go I can tell you that the new Fords have a transponder key which may have to be reprogrammed. In some cases the main ECM in the vehicle has to be reprogrammed. Only the dealership can do this. There is actually a TSB (technical service bulletin) published by Ford about that problem for '02 Explorer's. There is one fuse under the hood you can check first Fuse#2.14 5amp. Good Luck!

omg!! this is what is going on with my truck.
how did you get it fixed?? and also how much did they charge you??
