Let me try and clear some of these recent replies up.
A programmed key is a programmed key, Ford or aftermarket. The chip in the key emits a set frequency. When you program the key to the vehicle it's set to accept that frequency as an authorized key. The vehicle can't differentiate if that's a factory key or not.
You only need to cycle two programmed keys to add an additional key, not all programmed keys.
I still think the key you are trying to add is either the wrong key for your vehicle or it's defective.
Not from my experience. I've been a Ford salesman for 26 years and have programmed many keys. I've never had an issue adding a 3rd key when one of the existing two keys is not a Ford key. I even asked our lead service tech about your issue and he had the same idea, that the new key is wrong or defective.
Ok. Any recomendations on where to get a cheap 1 to try it again? Ebay or not. If ebay i would rather try a differenr seller n if next 1 works then get my money back for other 1.
I'd make a couple calls to local hardware stores or maybe even Walmart to see if anyone local has cheap pats keys. Buy the key from them and just program it yourself. If you can't find it cheap local look for a seller on ebay that has good feedback ratings and buy another cheap one on there.
I can't wrap my head around how they "cloned" the key. I have never seen a hardware store do this, so I'm missing a slice of the pie. Do they remove the chipset from the original key, and somehow plug it into a diagnostic machine? Can someone who has had this done, please explain what exactly the hardware store does, or the theory behind the technology?
Would another option beto bury the original, (or "clone") key inside the steering column near the ignition, and any cut key will work? Or does the key need to be somehow energized from the ignition to emit whatever signal it offers to allow the truck to start?
You didn't have to program that key from the hardware store in the truck right, ....it came that way. So it doesn't make sense that the truck still recognizes 3 admin keys unless the prior owner had 3 already programmed and lost 2 of them.
