Could Not Complete Pcm Reflash And Key Learn
Cuts Out

Just a reminder to never assume.I went to do a pmi on this truck at another shop because the pcm was replaced programming went fine.I could not relearn the key​.​ They both were ford key that looked equally well used.I assumed original keys​.​ When prompted to put second key in for relearn everthing went normal and said successful. In that past i rember it saying key was already programed​.​ After pulling my hair out i realize pids only show 1 programmed key a trip to the dealer and another key got it going​.​ The 2 keys that came in with the truck do both work after only programming one of them so obviously they had the same chip in them​.​ Oh and to top it off the cheap reman pcm they put in had more issues than the one it was replaceing.

I have run into this more and more lately. Finally I decided it was necessary to buy a tool to read the chips in the keys so I know if they are cloned before attempting. It takes 5 seconds to check the key ID's now instead of scratching my head like I did on the last couple before I bought it.

One thing you will run into is most key tools are kind of in a grey area. Most are made in China and a lot of ppl have mixed feelings towards them. Unfortunately there are things the manufacturers were not able to think about when building vehicles . The possibility that ppl would clone keys years down the road was something never thought of so there’s no way to know if you have a cloned key…
