Easy fix to blinking Theft light

If your Mustang suffers from a sporadic, blinking Theft light that prevents the car from starting, this video may help.
The PATS transceiver is a small plastic module that mounts below and around the lock cylinder housing. Its sole purpose is to read the key (transponder) code and send it down to the PCM for authentication. Its only about $30 and very well may be the reason the PATS system won't start your car.
Good luck!

Just got a 1997 mustang and couldn’t figure out what it was that was stopping it from starting !! So happy that was what it was and ur little filming man was great to. Thank you

[@RBJ_RebelEmbracer]

Hey man. I just want you to know that I went to a pick a part and brought a transceiver for $7.28 and my car works like a charm now. That's for giving me this information

[@kawh8719]

I have the same issue w/ my truck, my research suggests this is the fix. Thank you for the video!

[@user-vk3bd3lk3h]

I would like to thank the owner of the video very much, because this problem occurred in my Mustang 99 car, and because of this video, the problem was fixed without loss ❤️

[@KCunknwn]

I appreciate this video I have a 02 3.8 and like u I’ve been frustrated for months changing everything and was getting ready to change a key but now I’ll try this first

[@neonstatic7918]

Did it work ?

[@wkornf]

going to buy this part now! thanks so much. i have the exact same problem. Worked intermittently and i had to get the car towed, and of course the car started right up soon as i got home.

Hey to add to diagnosing which component is giving issues to the PATS. When you turn the key on the theft light will fast flash for around 40 seconds. Then it will flash a 2 digit code to you. Currently researching a code 12 on an expedition

[@sherryann744]

Thank you the information is Very Useful, , Great Job

[@cedesfacey7378]

You know if you stick key in roll window down half way leave key in for ten mins. Come back the theft light will be off and you will be able to start it and by doing that you reset the system! Won't have to take apart anything or all the extra stuff

[@jimkauderer9902]

That used to work for me, but it is not solving the issue any longer.

[@luhkasino9]

Wat if the windows dont let down and the theft light on??, is the problem bigger than just leaving the key on??

[@jasonflint3971]

Great help. Thank you!

[@Rtb323]

Have a quetion? Do you have to take it to a ford dealer to get it reprogrammed to match your PATS inside the key tho ? Or is it just based off the model of the viechle ? I tought anything having to do with replacing PATS in general would require a trip to the ford dealer so it can match the rest of the Anti Theft system and reprogramming it ? I could be wrong tho.

[@hermanrogers1325]

Yep that’s right thanks for the information the dealership will charge 2 grand for this I have a 04 Mustang GT automatic dark shadow gray my theft light is flashing a little faster and over night and in the morning it is on with no flashing so far my car still crank good with no problems so I think I will just go to google and buy one and have it ready just in case I know sooner it’s going to happen thanks

Ryan did your PATs transceiver fail due to a dead battery and attempted recharge or jump? My 04 Mach 1 battery died due to sitting in garage. I recharged the battery and now the Theft light is on and it wont fire at all.

[@brittanyblancett6503]

My 2004 GT is currently doing this..

[@wramsey2656]

@@brittanyblancett6503 my mechanic took a rubber mallet and wacked the gas tank several times to vibrate the pump in the gas tank. He said they run into this frequently when a car has been sitting for a while. So being an engineer i thought this makes since since the electric motor connection to the pump is mechanical there is a chance he is correct. I could not hear the pump start when my wife turned the keys so after the mallet wacking, the pump started and sent gas to the engine and it started. Good luck.

I have an issue where my theft light stays on "not blinking."

[@kevinnesmith3351]

I think that is what's wrong with my car cause the light does blink's fast an I went out to get fuel pump an driver module. An still no start

[@smartdummy5751]

I have a Mazda b3000 2003 and the 'anti theft' has been blinking on the accessory dash since I got the truck. The truck still runs. The anti theft light stays on blinking whether truck is on or off. Could it be a faulty transponder causing the transceiver to send the wrong info to the Anti-Theft module ->PCM? For example the key hit the ground or got handled too much.

[@KosherFinance]

Just give it back to the owner😂

[@smartdummy5751]

@@KosherFinance it turns out that a blinking auto theft light is actually normal. It means that the anti theft system is active. It's only bad when it's blinking sporadically and causes electrical problems like your car not starting.

[@dylonterronez9060]

I have a 98 gt mustang and my PATS system kicked on while I was driving on the highway. I didn’t know it was the PATS system at first so I put a brand new fuel pump assembly, alternator, battery, fuel filter, spark plugs, and wires and obviously non of that was it it was my PATS system the whole time. I got a new transceiver in it and it’s still not starting. My theft light doesn’t even blink how yours does it just pops up when I put the key in the ignition then goes away. I don’t know what to do at this point I’ve watched a lot of videos and heard a lot of different stuff but nothing works still. It’s at my gf’s sister’s husband shop he works at mal Hamilton Ford. He the supervisor of the quick lane and they couldn’t get it to work or turn it on. It’s going to the main shop and there gonna try to get it started. If they can’t is there anyway I can bypass the PATS system or something I really don’t wanna scarp my mustang.

[@xavierdelgado1023]

Wow...was it your pcm or key ?

[@xavierdelgado1023]

Ground wire

[@ufartface]

just bypass that whole crap with a hidden kill switch and a toggle ignition switch

[@dylonterronez9060]

So turns out my whole computer went out so I had to replace the PCM and ECM also had to put a new Ignition key reader in cost me like $1000 but now it runs and everything is fine. Only down side is I gotta take it back in the shop to probably get a new PCM again because I think the one I got now witch is only like 4 months old is going out.

Check the PCM relay. It’s located under the hood in the box on drivers side. We picked one up for our f150 for about $5 from Ford. You can pull the relay and watch how the theft light blinks to know what code it’s throwing. If the relay is bad it’s a quick cheap and easy fix
