Here comes with the similar problem:
Program 2019 Ford Expedition remote / start key using xhorse universal smart key. Remote working, car recognizes when key is in the car, green light on the start button but car doesn’t start only when key in the slot.
Answer:
You have generated wrong remote. Xhorse cannot do proximity with 902MHz.
Xhorse and autel had 433 & 315mhz frequency and may be converted to one or other but this new truck use 902 mhz that this smart universal key don’t have so it would not work!!!
These are 902mhz, xhorse, keydiy, or autel, none of them can generate 902mhz keys.
YOU HAVE TO USE THE REMOTE WITH THE SAME EXACT BUTTONS!!!
This new generation is called motion sensing fob. From 2019 and up.
The FCC ID, part number, and button configurations must match with the original remote.
