Nie doszukałem się info czy zadziała z Mustangiem niestety.
Na forum US wyczytałem, że do podłączenia ktoś użył OBD II Scan tool. Procedura szerzej opisana poniżej.
Click the "Open" button
Now Click "Read from BCM"
There will be a progress bar on the bottom of the screen and the the FoCCCus app will read your car's ECU to get all the correct values.
4. Once done, I advise waiting about 30 seconds before unplugging the OBD-II from the car. Then turn off the car. Open and close the door to ensure it is off.
(Your car will start throwing you a number of random error codes on the screen, and give check engine light and every other kind of light. This is just part of the process and will need to be cleared later.)
5. Now you are ready for the last part. With all the value you uploaded into the FoCCCus app, scroll down to #239 MyKey. When i did it, the value was set to "2". You should click and change the value to "0".
Once you change it to "0" you can plug it back in to the car and follow the previous procedure (Put car in accessory mode). Then click "Write to BCM"
This will make you car have 0 MyKeys.
After, you will have repeat the process but this time changing the value of #239 to a "1" and rewrite it to the BCM, which will turn off The MyKey feature!
Wygląda na to, że tutaj w BCM to jest poprostu przewijana lista opcji i trzeba zejść do #239. To podziałało w Focusie, nie wiem czy zadziała w Mustangu.
Przed takimi zabawami mimo wszystko proponuję zaopatrzeć się w drugi klucz
