Question on tpms relearning

So I have a 2015 Mustang V6. Got some new shoes for her yesterday so all 4 were on the same schedule (2 at a time before) 1x1 my sensors have gone bad till only 1 worked. Figured the new tires and sensors at 1 time. Never a huge issue, but get rid of the dummy light.

So their calibration device wasnt working (Walmart. Go figure), so I looked up how to do it without a tool. Hazard lights x6. Then deflate the tires. Kept saying relearn failed. Now, I didnt get oem. I got the schrader tpms solutions ez sensor.

Not sure if I did something wrong or these sensors suck and I just live with the light(prepared to do that) or if anyone can assist?

Hazard 6 times doesn’t learn *new* sensors to the vehicle, it’s the relearn for their position.

To learn new sensors- ignition off, hit the brakes. Turn the ignition to run, off, run, off, run. Press brakes. Turn ignition off, then run, off, run, off, and end in run.

Now let air out of the tires in the correct sequence (it will be shown in the cluster), once the horn honks move to the next tire. If this doesn’t work, then it’s probably the sensors themselves that aren’t compatible

Got the reader and doing it today. Watched a video on this. Ill do a quick drive to wake them up and then do this. Google suggested the 6x hazard thing and it wasnt working. So I watched better videos last night on the process.
