I can repair the checksum errors but I doubt that's what's causing the problem. They occur for the hashes of unused keys. Have you scanned EIS, ECU, ETC, ESM and DDM for error codes?

Key 6 was marked as unused when it was in fact used. Still a good idea to scan those modules. :)

there's key 5 from the second processor's content, made for NEC

the malfunction of electric windows, hazard signal, air conditioning and much more could be a result of soldering fault. if this key won't work, then you have to check your solderings.
