Possible to Generate Ford 902Mhz Smart Key with Xhorse Key

 This is a frequently asked question of Xhorse keys. People say that no one can do Autel ikey and Xhorse either.

Here is the clue.

You can generate a xhorse proximity with 902Mhz profile (image below).

It works, just generation and test frequency.

People have made a lot of these on the Xhorse universal proximity type.
The remote worked, lock, unlock works.
The remote start worked. But to starts the vehicle, only when the key in the slot.
The proximity function won’t work.

Xhorse Smart Key 2019 Ford 902Mhz Remote Works Car Not Start?

 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.

Program 2022 Honda Accord Key with Xhorse Smart Key?

 Honda Accord is the new system. Which key can be used to program proximity to the 2022 Accord?

2018-2022 Accord key fobs all look the same.

If Autel asked you if it is newer than a 2020 so answered No. If this year uses the old style Honda Prox, the Xhorse ones should’ve worked.

The process is very murky, specially the instructions. But they all took.

Some people did a 2022 Accord AKL, tried an aftermarket key and it failed. Used a xhorse universal and took it in with no problems.

Xhorse universal smart key worked. Tried aftermarket and original OEM but no lock.

But once you do that, it’ll never accept OEM keys. Ever. The BCM software has been screwed up. Only XHorse keys will program to that BCM. He could’ve easily gotten the car started by programming an XHorse Prox, but the original keys will never work. Its like VW/Audi.
