I haven't tested the RF function enough but in 2-3 times the RF worked from the start. I think the RF gets synchronized after you start the car. Do you remember on what cars this fnction worked and in what cars it didn't?

I never had IR issue. If it starts then remote works as well here. I get keys in three different folders from the server, One for old key, one for new one. I use the middle folder and seems to work best for me.
So maybe you're using a key file ment for a different key.

yes 051 is the correct folder to use for NEC keys so thats definitely not your problem. Check the soldering of key chip or that you have not damaged other components around that area, fault will be with key, not with key dump, done tonnes of them and never had a problem ever

95% of the time soldering is to blame if there is a problem
