We lost the keys to our 1999 Ford F250 (F150 body style non super duty) truck. Every parts store told my husband he didn't need a transponder key so we purchased a new lock cylinder set. He removed the old one and accidentally broke something we later found out was a part of the PATS system so we purchased a new one and replaces that as well. Tried with the non transponder key, theft light is still on. Purchased a transponder key, had it cut to fit and tried the programming DIY found online. Theft light still on, turns over but doesn't start. It's getting fuel. What do we do now?? Please help.

 

Dealer. Keys need to be reprogrammed to the pats system. Probably locked out the system by trying thr diy method

 

It is an anti-theft system and it is working as designed since you are unable to start it. To fix it, take it back to the Ford company that designed the system and pay them what it takes to fix it. And I would expect them to require proof of ownership.
I already answered this in your other thread in the Super Duty section.

Any good locksmith can also do this for less than a dealer will charge.

 

You need to have 2 good working keys with separate codes in order to program in a new key yourself.

 

Mandy; If there is a Theft lamp on the dash you need a coded key.
That in itself tells you there is PATS present.
The Theft lamp flashing also tells you the same thing.
If you put the key in, turn the ignition to Run, leave it in that position for a couple minutes it will flash a code.
That code likely will be telling that the key signal is not being received, if the code description was looked up.
Bottom line is programming has to be done by a qualified service for two keys that are programmable.
Good luck.

 

I apologize for wasting your time, this forum is definitely not what I was expecting it to be. I was thinking it was a forum for people trying to HELP people, not just stating the obvious. Yes, anyone with half a brain or the extra resources would first and foremost take it to someone who knows what they are doing. Who needs the added stres, right?!? In fact the first thing out my husbands mouth when anything breaks is normally "pay somebody, they offer specific services just like me, promote the craft!" Unfortunately, my husband had been displaced from the oilfield for 1 & 1/2 yrs taking crappy low paying jobs just to "say" he was working, having his vehicle repoed had to go to this extra POS we had as a spare. Dealer wanted too much and we had no other option but to try to do it ourselves. Trust me, if stealing a vehicle was ever a thought it definitely would not be wasted on a 18yr old vehicle..

If only they were all as simple as our '49 F-1 we'd have no problem!

Good day gentlemen.

 

Like I mentioned on the other thread, if you have to ask then the answer is most likely beyond the skill level of most people. Not trying to be mean or unfriendly, just stating a fact. 5 different users here took time out of their day to help you and have all given you the same (correct) answer: pay a Ford dealership or licensed locksmith.
So you say you contacted a dealership and it was too much (like we said).
Did you contact a licensed locksmith and shop around? (Like we also said)
You might even find a locksmith that will make a house call.

It takes specialized software to write to the PCM and program keys. That's just the way it is, and has been that way on F150s for 18 years now and Super Duties about 10. Some Ford cars longer than that. Most of us have figured out to not lose the PATS keys. And if that happens, it is an expensive lesson not soon forgotten.

You could try Forscan. You will need to get a license to use the full version of the software in order to enable the ability to program PATS keys. You will need a computer running Windows, since that is the only version of Forscan that supports this feature. You will also need a wifi or Bluetooth OBD2 dongle or OBD2 to USB cable. It is a little bit "techy" to do it, but where there's a will there's a way, right? There is also a Forscan support forum. Good luck.

You may find that after the time you spend trying to figure it out you would have rather paid someone to just do it.

 

I'm sorry you didn't like hearing the facts.

As stated above, go buy the right tools and you can do it yourself. There is no work around to do it without the proper software.

 

This is a forum of people trying to help people...free of charge and on their own time. What you were told is that you cannot do what you want all by yourself, it takes some knowhow and some specialized software. Not hearing what you want to hear is not the same thing as not receiving help.

 

Eighteen years ago theft was a consideration to deal with. Heck even even here in Houston auto theft of these older trucks is still a thing. I use my truck to get me to my low paying job and to put me through school and had to bite the bullet when the slave cylinder went out a week after I got it when I was temporarily out of work due to a back injury. It happens and a non Ford dealer did the job a whole lot cheaper. If I recall correctly, a locksmith I took mine to to remove the lock on the spare tire that is original to the truck (if I had known that I wouldn’t have left San Antonio with that spare) charged about $50 a key and included programming. Not saying that this will be true to any other locksmith but may give you a place to start.

 

Now you can download Forscan free at www.forscan.org. You'll also need an ELM327 adapter. I bought one from Amazon for less than $30. Then you can program the keys.

 

Letting some spam get in. Tsk, tsk.

 

I think it's important to note it would properly be call the "Ford PATS" or, the "Ford PAT system".

Not the "Ford PATS system."

Please make a note of it. I'm headed to the ATM machine, after checking my VIN number.

 

If they have AAA they will send a locksmith out to rebuild a key at no cost. The one who came and did my truck built a key for the truck by VIN number and gave me two keys for it. He programmed the key and all that and made sure it cranked before he left.
