For those who don't know, the PATS (Passive Anti Theft System) has been standard equipment on Ford cars and their counterparts for a few years now. A simple idea, put a transponder chip in the key and unless the correct key is used the car won't start. The early PATS had the ability to make a spare key if you only had one original key, but later this changed so that 2 programmed keys were needed.
A few weeks ago I picked up a 2005 Taurus that only had one key. No problem, a quick trip to Ford and they quoted $40 for each key, $20 to cut each to to fit and $100 to program the pair. Had to be a better (cheaper) way, and there is.
There is a free program called FORscan, which works on Windows and Android
https://forscan.org/home.html
The software on it's own is great and is better than most scan tools on the market, plus it's free. Provided you get an extended license (free at the moment) you can also program spare ignition keys.
In my case I ordered 2 uncut keys and 2 remotes from E-Bay for $14 https://www.ebay.com/itm/2-For-2005...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 And an ELM327 adapter for $5.00 https://www.ebay.com/itm/ELM327-V1-...320060&hash=item4b5ef42991:g:zxgAAOSwDkpaZvL9
Had the blank keys cut at my local hardware store for $5.00 the pair, used the software and I now have 3 working programmed keys. $24 as opposed to $220.
It's worth getting the free software and the adapter just for the scanner functions.

If it's an older car of not great value you could remove the chip from the 1 working key and tape it to the 'receiver' which is usually near the ignition switch. Now any key that is cut to physically turn the ignition barrel will start the car without needing a chip in it.

Sort of defeats the anti theft then.
It's just a way to avoid the dealership charging an arm and a leg to get new keys programmed. And once you have programmed 2 you can do as many more as you like via the PATS system itself.

Yep, that's why I said a vehicle of low value :tup:
