Vehicle was working smoothly with one key for the past couple days. After gaining security access and trying to program the keys it turned on hard stuck for all keys. I tried doing as much research as possible and from what I’ve seen I have to reset parameters before programming all keys new… it seems now my info for my main key ( taped one ) is no longer reading since my key was forgotten. So now I’m in a loop trying different methods of programming the key. If I can get the main one to work that would be beautiful since it is original. However I have three keys I want to program.

I’m going to try one Amazon and one original. Complete the process. Then attempt to program the third. I also have fobs I want to program.. but they are from Amazon as well. So if this doesn’t work out right I’ll try that link out. Thankfully the place I work at cuts my keys for free so I don’t have to deal with the scamming lock smiths or dealing with Home Depot/ace telling me no for liability reasons.
After time of course the light turns off completely now but if I remove it and insert it again it shows it won’t start. And repeats the same process.
That's the problem I've had with aftermarket keys. If one isn't able to connect to the receiver, you won't be able to program any of the keys successful and the vehicle won't start. Granted, it could be an issue on the receiving end, or even an issue elsewhere. But PATS programming only completes properly if two keys program. If only one programs you won't have any functional keys. So that could be what is happening here.
Can you scan the module dtcs? The IC module might show some DTC's that might be a clue here. If there are communication issues with the cluster, those usually show as module DTC's. These cars were the first Mustangs to have some modules, mostly the ABS system and the instrument cluster. Sometimes PATSs issues do show up as DTC's there and that can give a clue.
I've used ForScan to do key program and module initialization on these cars. Should be the same functions as your Autel, but i'm making the assumption it shows the same info as ForScan with regards to programming errors and DTC's.

When I get off work today I’ll give it a scan to see if I’m having any trouble codes that are new. You’re saying the autel should be able to program it no problem then, the issue lies within the key itself. I’m going to give it a shot getting a better quality. I mean truthfully it looks the same on the outside. I can’t tell the difference.
It's a fair assumption to make, and I would assume the same. I dont think the tool is the problem. I've just never used my bidirectional scan tool i've always used ForScan.
I think it's either keys themselves (or maybe 1 of them at least) or it might be related to the underlying error that was present before. That's why I'm suggesting give the modules and scan and see if any DTC's show.
The only reason I can think of vehicle immobilized at the moment is because battery level is too low but I’m currently charging the battery, because I have other codes for voltage too low. I’ll charge it up clear dtc scan again and see what happens
Also just found these codes after scanning

I’m trying to see if surely has a function for the PMI to inhale the data of the pcm into the pats so I can get it going since at this point I believe it’s only a programming issue, “user error”. Possibly the result of an incompetent mechanic ?

I want to say I’ve seen that last code when the cluster is not initialized to the ECM. Not 100% sure as I didn’t log the code. That’s when I would do the cluster initialization in ForScan prior to programming the keys.
One of the other codes suggests the pats key isn’t programmed. That would trigger theft mode.
The vehicle is cranking and no start right? Is there any menu option to initialize the insteuctment cluster module? Essentially you are programming the cluster to the ecm.
This one is puzzling. I don’t fully understand what is going on here.

The pats module isn’t initialized with the pcm. Because the handshake isn’t present I’m assuming that’s where communication is lost. Apparently my no directional scanner does not have a relearning possibility. Forscan would be needed here to relearn the, pats to the pcm. This is correct I order some new legs from stratec as well as an OND link/adapter for for scan I’ve never downloaded it on computer before so I’ll see how it goes
02 V6 3.8l has stand alone pats so it’s type A securilock if I’m correct meaning it’s outside the instrument cluster. This seems like the simplest one I believe to have as if needed there is a transceiver amplifier if only one key is left.
