Anti-theft light is blinking and won't start

How does the key unhook your battery ive always had to use a socket or wrench

I use Ford fiesta but used different key to start after but couldn't start then we used the original key the red light comes on but the car doesn't start

I have a 2008 Ford expedition the anti theft is on and it won't start

I have a 1999 Ford expedition the Anti-Theft light is on blinking rapidly and it won't start I bought a new battery it still won't start I'm stuck I also went and bought new keys with new chips I haven't installed them with the new tumbler I'm thinking maybe I could fix it without doing all this cuz the chip is not in my key when I bought the expedition so I'm assuming the key is under the loop the lock loop under in where the ignition switch is but I don't know I don't know I need help to start my car

Unhook your positive cable with the key on for 30 minutes.then hook your cable back up with the key still on.that should take care of the light

I have a 2005 ford explorer and the anti theft blinking have no crank no start what do I do

Try turning your key on and unhooked the positive battery cable for 15 minutes and hook your positive battery cable back up with the key still on.

First off the time that the battery is disconnected keeps getting shirter by 5 mins secondly its a pats security system issue just turn the key to the on position for about ten mins your problem should go away

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.

Ì got a 2002 ford f150 theif light. Flashing no crank no start now when I push on the horn the cluster lights go out an the theif light like there is a short in there any one no

Losing my kitty but had my check placing lunch with me with transponder around the ignition cylinder on cell phone I was going down the road one day and my explorer just shut off it would fire right back up but then shut right back down got it hauled home and started going over one thing at a time first name I replaced with the terminals after I'm hooking the battery for about 30 minutes and then letting them touch to remove all charge from lines so it didn't hold code and the %#*@ thing fired right up, got going and the road toward a friend's house it shut off on me again fire up but was missing real bad and you shut down I managed to make it up the hill to my buddies house and now I sent the driveway for about 2 and 1/2 hours messing with the emissions... Tore dash apart and pulled off sensors down to the crankshaft sensor master air sensor clean made sure there was no broke wires behind dash thn turned ignition to on pos.for 15 mins. back to the AC pos.15mins Thn off pos 15mins crank right up no prob.

Until it stopped reading my check that is

This comment is editing my first comment there were no kitty cats involved.,. Supposed to say lost key but had chip

My comment is all messed up talking to text let me know if you can't make anything out and I'll explain further

That will turn off the theft sensor Will it work for a 99 expedition

Turn the key on and off on an airplane off repeatedly until you hear your doors locking unlock that's resetting your transmitter key so that it tells your computer that it is the right key and okay to crank .. once he is set on the way in programmed the theft light should go off allowing fuel pump to work in your vehicle to crank... If that's not the problem and that fights the one check fuse inside and relay under hood

I'm having problem now where it's after eating my ship which is out of my key and trying to find the right spot again and getting it to try to read chip again I busted my check which had liquid in it does this mean it will not read that chip??

I really need to stop talking to text... Correction to first guy night I am having that problem now where it will not read my chip.. when trying to find the correct spot again I busted my chip there was liquid in it does this mean that ship is damaged and it will not read it

Okay Team So I have a 99 Ford explorer XLT and I lost my key but still had chip(transmitter) put it with transponder and I was good to go... Noticed my power windows gradually stopped working and then my chip became harder to read until it stopped reading chip all together ( let me just add that I replaced my ignition already once, purchased at your local auto parts store ignition with transmitter, Thn lost my %#*@ key again and had to bust out ignition AGAIN) to finish setting my key to computer all inside was turn key to one position and then to off position, repeating the steps on and off until your doors lock and unlock. Boom key ready to go. Let me hop back to the beginning, I was using a flat head screw driver, putting it in up in where the ignition cylinder would go lining up with this gear inside that I turn with if I hit screwdriver which shoots a rod down through steering column I pranking the vehicle.. but by using the fattest screwdriver I have broken off the teeth to this gear inside connect to
