Problem: 

I have a problem generating Ford F150 ID49 remote with xhorse vvdi key tool plus. It says the latest remote does not support 868, 902mhz frequency.

Answer:

The latest remote cannot generate 868mhz, 902mhz remote.

Use the old remote before v2.0 to generate.

You cannot tell the remote version from the appearance.

You can identify the remote versions xhorse key tool plus.
