Trying to generate Fiesta (Old Type) KeylessGo ID63 remote using Xhorse universal smart key and smart key, But once generated it, still reads as id46 no change .
Advice:
You need a separate transponder in the key, the remote function is the keyless part transponder is emergency blade for start.
Just program remote and leave them with a HU101 key blank cut with transponder inside for emergency start.
Finally, it worked
Just added chip first them added remote works fine, just no emergency start as no place to put chip in remote.
They have old key with emergency blade and chip anyway as was remote that was playing up
So he’s was happy.
Hope it helps!
