Anti-Theft Turned on Car wont start but turns over?

Have it tow to the repair shop !!!!!!

If the anti theft light is blinking and you say that everything else fine.. My first thought is that the key is not programmed to the vehicle. The key has a internal chip that must be programmed to vehicle in order to start. Now my other question is, Is the key your using for the vehicle the original key or have you just recently had a key made? Regardless, in order for the yur Tribute to start, the key. Or keys have to be program to vehicle by your neighbor dealership. Thats the reason for your anti theft light is blinking

If the anti-theft light is flashing, I would think it is a problem with the key or the anti-theft system. The system would kill the power to the fuel system.

NEED TO RUN THEFT CODE CHECK TO VERIFY WHAT PART OF THEFT SYSTEM IS FAILING .COULD BE JUST KEY ,IGNITION SWITCH OR AN ELECTRICAL PART

very well could be due to anti theft issue. i don't recall the keys getting locked in the ignition from this though. try turning the key to the on postion- not cranking and leave it there for 15 min, then turn back off. do this three times. you may get a blinking light on the dash- don't worry about it. on the fourth try and start it. what you are doing is telling the alarm- i have the proper keys so let me take my car!

try using a spare key first

Do your locks work on the SUV? Somethings the locks can set the anti theft off. But if your locks work then that means your the chip in the key is bad or its not reading the key at all. More than likely you will have to get a new key and have it reprogrammed. Dealer is the only place to get the key.

take the positive side of the battery off for about 3 seconds and then put it back on to see if this will reset the security code

it sounds like the immobilizer is faulty. this will shut off the electrical feed to the starter motor. you will need to take it to a garage to get this fixed.

hope this helps.

does it have an autostart? if you have two keys (this will only work if you have two) turn the key to on in the ignition and wait till the theft light goes out do this for each key this may fix your problem.
