Between the two methods available they should work. If you are having problems I would try both methods and make sure you car really conciseness of the times in the process. It is not conceivable that you have a car that is not able to recognize a standard reprogram command. Everyone has used the available methods and they have worked for every model and year so I can only assume operator error.
I am trying to be pleasant, but to complain that it doesn’t work is likely BS and you need to perfect the simple method…
Some people dream of speed-others create a damn jet powered shopping cart.
