Xhorse Subaru XM38 vs Toyota XM38 for Subaru 8A Smart Key

Some users reported that they failed to generate Xhorse XSSBR0EN Subaru XM38 remote on Subaru 8A/4D smart key models.

For example:

Tried to generate KeylessGp 4D, Legacy 2020-2022 8A, and Crosstrek 2018-2022 8A remote with Subaru XM38 but got an error.

Solution:

Check the compatible remote type in Xhorse App.

You should use XM-28 Toyota or XM38 Toyota remotes for Subaru 4A/8A smart keys.

As for the Subaru XM38, it is the universal XM38 remote. 

These keys aren’t the XM38 Toyota special keys just nxp orange keys don’t work for Toyota or Subaru.

It can be used to generate remotes compatible with the XM38 Smart Key option.
