Car Won't Start, Theft Light Flashing Slowly
So my 2000 Taurus SE Flex Fuel stalled on the road and wouldn't start again a few weeks ago. My former mechanic friend looked at it and found that the alternator was bad and the battery was dead, so he replaced the alternator and got the battery recharged. Problem is that the car still won't start - there's a small click sound coming from under the dash but it doesn't even try to start beyond that. He had the starter tested at the store the same time he tested the alternator and it was good.
The Theft light is blinking though, but it is blinking slowly - about every 2 seconds - both when the key is in the off and the on positions. He thinks this means that the keys have lost their programming, but everything I find says that's only true if the theft light is blinking quickly, plus I think it's kind of unlikely that both of our keys would lose their programming at the same time. Anyone have any other ideas to try before I call a locksmith or have it towed to the dealer?
Thanks in advance!
