How to Program a Ford Key with Only One Key Using FORScan on a 2002 Thunderbird.

This video shows how to program a Ford key with FORScan when you have only one key, what can go wrong, and how to recover from a worst case scenario

.Here is the OBD2 ELM327 adapter that I used:

I really appreciate you showing the failure and explaining how it was remedied. Between you and the polite commenters, anyone should be able to get their ford keys working off this video <3

Followed these instructions for my 2006 expedition and it worked great, no errors. Thank you.

Just programmed an additional key for my 2014 escape and it worked perfectly. Bought a $16 ODB2 reader for $16 on amazon and turned off MyKey restrictions. Bought a $11 extra key on ebay and programmed the key fob. Paid $75 for locksmith to cut the new key, then used Forscan and this video to program the new key. Worked perfectly … thanks!

I guess the best place to do this method right infront of the locksmith shop. Just in case 😂

Thanks for the video. I tried to program my 2010 Ford Fusion Hybrid via the key on off 8 times, but it wouldn't work. I thought maybe my car already had four keys programmed. So worst comes to worst and if i erase my good key, I'll call a locksmith. The good news is using Fortran, I could see that it showed only 2 of 4 keys programmed. Long story short it worked and no locksmith was needed. Now i have 3 of 4 ignition keys programmed.

I have programmed new keys for two vehicles with Forscan so far with no issues.

I have 2 cards for mazda cx 9 from 2008. I have a problem with keyless go. Once it works fine and in a moment I have to start the car with a metal key. The key flashes red while driving. Not when the immo is flashing and I can't start the car. I suspect that it is the keyless module or the fault of one of the antennas. Can I use a forscan to reprogram my cards? Is it safe?

Ford Edge 2013, only 1 key, and it is nearly dead. I’ve read a lot about this but, the problem is that I’ve been getting conflicting information. Yes I can with a spare key and the ONLY key that we have… and then NO you CAN’T add new key with only 1 key. So… as all of you know this isn’t something I can be wrong about I try. So, that being said, can these specific details, still be ok and get a second key on our own?

I lost all the keys for one of my town cars, luckily I have multiple town cars and for some reason the ignitions are the same. So I can make a copy of the key and I’m hoping I can program additional keys with this method without needing the original

[Jpilgrim]

I had a feeling that this was going to happen when I saw you put the new key in the ignition. It looks like the key you were trying to program was a generation newer than you original key. It’s obvious now but that will not work lol. I keep some spare blank keys like these for any situation I need to program PATS and the customer only has one key. I’ll take the transponder ring loose from the column so I can stick a blank inside of it to trick the system into learning the second key.

If you have only one working key and you want to add additional key. You do not need FORScan or any other scan tools.
Follow my instructions and it will work for you, I did this recently to my 03 mustang which has the Ford transponder key.
First insert your original key into ignition and turn to on position, wait till alarm light to turn off, usually 5 to 10 seconds. remove your original key and place it right next to the ignition column. Place it near the ignition is at. This tells the car that the transponder is in proximity of the ECU.
Next insert your new key and turn to on and wait for alarm light to go off 5 to 10 seconds. Remove key.
Your new key is now programmed as the second key.
Now you have 2 keys that is programmed to your car.
Now that you have 2 keys programmed, follow the simple instructions to add additional keys.
You are welcome.

I have forscan and a spare key I ordered off Amazon. I hope the transponder works. But either way I’d still have to pay $100 for someone else to program it. It’s worth a shot. I wonder if the car will exit programming mode if you disconnect the battery.

i just did the same thing and it the original stopped working, so i got 2 new keys and used the option to delete and program all keys and programmed them both and it worked again. so no need to call the locksmith, just buy another working key.

[garysincliar]

Will I need to connect the pc into car obd port.

[johnmarken]

curious why you posted a video purporting to show how to use forscan to program a second key when instead you had to call in a locksmith. LOL

[wyattburp]

I am trying this on my 2011 f150, i keep getting an error security access denied after programming has started, anyone know why?

[lortonlife]

What hardware/ cable are you using from
Laptop to
Obd2

[evanleonardomirandacruz]

But I don't get it, if I have only ONE key, will it work or do I need two keys anyways?

[greggriep]

Google how to test blank pats keys with forscan. Then you will know if it will work.

[wegiel]

I cant understand why your keyes were ereased when you used first option to only add a key without ereasing theese which have been already added.
