Thanks man, do you have a diagram for these files? Should i remove the chip?

Thats a complete list of PCF7xxx for all frequencies and sub versions of 434

It didn’t work out
Key can start engine when its near ignition coil.
However i noticed that Vvdi is reading fem with 433hz
However the original antenna installed in 434hz, old key as well is 434hz and its fully working.
I tried another 434hz huf 5663, same results, i even tried eeprom of huf7673 same.
Another note here, when make frequency test when i write its accurate eeprom its gives me 433hz, but when i write eeprom of huf7673 like the old key, it gives me 434hz.
I know alot of people struggle with this frequency, and i know personally its doable, i hope someone can share the correct info.
