2004 Ford explorer 4.0 won't start and security light flashing constantly

Won't turn on security light flashing constantly

I'm having that same problem, 04 explorer, everything works, radio lights etc, but when I try to start nothing happens. But sometimes it will start if I wait a little while, its happened a few times to where it won't start for a while. I'll keep my eye out for this now, hopefully it's this simple of a fix.
Thank alot for posting

Thanks man! Had the same issue, didn't have to call a mechanic.

Your a chqmp man. The big difference between security flashing, either a bulb, or message on odometer. You make that clear. THANKS.

Leave old key in switch turn it to start but don't start...leave key in for 10 minutes to reset. Then try to start. Or disconnect negative battery terminal for 10 minutes. To reboot.

Could this be the issue for theft mode on my 2001 ford explorer sport trac? Originally my shifter broke one of the bolts, so as soon as we starting messing with it the truck wouldn’t turnover anymore.

My 2004 Ford Explorer was doing EXACT same thing after i had let it sit and battery went dead, then i tried jump starting it and still got nothing. Tried unhooking battery and waiting a couple days, shifting from park to drive and back to park, using my other original spare key, checked relays, fuses, ect. nothing worked. Had it towed to mechanic for $65.00 and he did a diagnostic scan on it and told me the computer was not recognizing either key. He had to delete both original keys and reprogram them and for $90.00 i was back on the road. He said it could have happen from battery going dead and trying to jump start. If i had not unhooked battery prior he could have told me from the diagnostics, but i guess when you unhook battery you reset the computer and lose all faults or errors in the computer. I don't know. I do know for $90.00 it was well worth it, just the tow bill sucked. Good luck!

Locksmith came to the house and cut/programmed the key in the driveway. Fired right up....

[MilesProwerStudios]

Do locksmiths program the keys, or do you have to pay $50 or more to get a programmed

[parisprice]

If you have remote start where you put the key in the egnition then press the brake. Use remote start first then put the bad key in and turn to start it will reprogram your key.

[parisprice]

Check to see if you have two chipped keys first. If one stops working use the other to start then use bad key it will reprogram.

I just got the same problem today, you say a locksmith can cut a new key and it works with out a ford dealer programing it

[foreignyetdomestic]

if ur gonna sound this good *** surely this a TOP or a VERSE ?

Pascual el antiteft se prendió y la llave se quedó en el switch no la puedo sacar..que puedo hacer

[goldrush]

I wish I would have found this video before I changed my battery starter and starter relay. I grabbed my spare key and damn if it didn’t crank.

[crusher]

Tried new key. Didn't start. Same problem.

[colbolt]

That's not a fix! Its an obvious solution which everyone knows!

[erickhernadez]

That doesnt solve all the theft lights flashing rapidly... after it flashes rapidly wait about 20 secs. It will pause and blink slower; 2 sec... blink .. 1 sec. blink . Blink. And it repeats the same pattern blink over and over unless it has more than one pats problem

[clutchtc]

Getting same problem 1.6 code. Had ford reprogram pats & keys... same thing happens.. it’s so bad Ford is telling me they can’t fix it.

[bigsmoke]

Hey I hope someone reads me....

The same shit is happening to my car. Ford explorer 2004

Got a new key today, just came back. Tried this... and it didnt work. I dont know what the problem is.
I put a new starter 3 days ago.
Now a new key, and still nothing. Anyone have ANY idea what's happening? Please feel free to comment, I'd appreciate it
