1, Try turning the key and moving the shift from park to drive and back. Then try starting it again!

2. Try your spare key in case the chip has failed in your primary key.

3. If you get it started, go to an Auto Zone and get a computer read out to see if it will tell you what the issue is.

UPDATE 6/20/29

Use the trunk to first lock the driver door then unlock it.

Do you start it while you shift at the same time or do you shift first and then started or do you started then shift so what is it what's the combo

Some anti-theft lights blink by default ( a small red light near the dash, for example is there to warn off thieves ). If this is some other type of light then disconnect your battery (negative first then positive) for 30 minutes and reconnect in reverse order (positive then negative). This should reset the computer. You will loose presets in your radio.

I had the same problem..I tried every one of these other methods with no luck. Took me a month to figure it out and luckily I could still start my vehicle and bypass using ignition key by touching something long and metal, e.g. A screwdriver, to these 2 bolts under the hood and start it that way but what a pain everytime I needed to start it.. I finally found this answer in an old forum somehwere and it worked!

Answer: Anti theft system had been activated, you need to push the 7/8 9/0 keypad buttons at the same time then enter the unlock code to disable the system. Sometimes this can also work by using the door key to first lock the drivers door then unlock it.

Whats the unlock code

I had an 01 expedition with anti-theft light blinking and took it to dealer to reset. I was told fuel pump was bad. Anti-theft shuts down the fuel pump so they're idiots. Transponder in on the ignition switch was not reading chip in key so I dug the chip out of the key and removed transponder from ignition and taped the chip to the transponder and stuck it up under the dash out of the way. No problem since.

Use your key to lock and unlock your door locks from outside. Cycle them back and forth all the way. You cannot remove it.
