Fob not working remotely after FEM ISN change - It3_Magic - 22-09-2023
So guys рдят 3 of my trouble with this car,
After setting donor ecu isn to FEM, had to do fresh immo, so add new keys, I added new key, sucesful, car start but only when holding key close to the steering column, no lock/циLoск. New battery in fob etc.
I tried 2 different new keys, also original key virgin and reapply, nothing.
Decided to try different FEM, even changed frequency from 434 to 868 and added another key, still same.
ANy ideas?
tools: ACDP and CGDI

90% of the tools cant refresh 434 keys correctly

I agree, in my experience original keys virgined don't work remotely. Use new blank keys from trusted source.

hello
Which tool is capable of properly resetting these 433 MHz units to a virgin state?

The EEPROM you read out must be put into the same FEM. You not use the original EEPROM in the donor unit
