You can’t unlock or decrypt the tune file without the key. Only the tuner who created the tune has that. You’ll need to remove the tune/revert to stock tuning and find another tuning shop that does not encrypt or lock their tune files. But like someone else said, even with a locked tune, the OBD port should work and scan tools should function. Best to revert to stock and verify the OBD port is functioning as it should.
I have customers who needed their PCM reflashed to stock because either they could not revert to stock (lost the tuner) or they bought a vehicle that was tuned and didn’t realize it until they brought it to the dealer for service. At my shop we use Ford tools to flash to stock, IMO that’s the best way to go- start with a clean PCM calibration then retune.

Encrypted tune
Greetings,
I have a 2019 F150 with the coyote engine. I purchased it from a dealer a couple of years ago and it had a tune SCT I’ve been told. The tune is encrypted, so when anything is connected to the OBD port, it reads nothing. My ECU is invisible. I can’t use fordscan to adjust tire size, Bambi mode, etc. I went to a local tuner that specializes in SCT and same results, nothing comes up on the computer once attached to the OBD. He suggested having the dealer return to factory, so that I can retune again. Dealer wants $500 to convert back to stock.
Any ideas out there to avoid having to retune? Don’t know why the previous owner would install an encrypted tune. Thanks for any feedback!

I had the same problem with my 19 2.7 tuned on a Sct device with (BCB 93). The shop couldn't read any codes with there scan tools. Had to pull the codes with the device.. in my case my PCM was over charging my battery and had to change out the PCM . I'm not sure why but it did happen too me too

hi buddy, i just saw you opinion about MPT vs Oz, now i am in a lot of doubts between the 2, so i reached out to my local tuner and advised him, he asked me for the tune file, if you can kindly attach it that would be really helpful to review the differences and go with one of them
best regards

I ran into the same issue after hooking a Flashpaq (not recommended) to my truck . ForScan couldn't read it anymore. Luckily, I was able to get a new Roush tune. It did ask me for the PCM number, you can get that from the MotorCraft site. Should be able to re-write the AsBuilt data.
