2002 LEXUS IS300 - Transponder

[digitaltech]

EEPROM 93C56 - UPA did not read incircuit- read off board.
Pictures attatched.

I haven't used AVDI in a while and all it has now in TAGKEYTOOL, is TOYOTA ALL MODEL, LEXUS ALL MODELS.
When i load either dump, x8 or x16 bit organization, tagkeytool detects it as 4d from visteon immobilizer then gives error "incorrect dump"

Anyway anyone can extract 4c info from either dump ?
On another post another user said that for he used RX300 in Tango to write transponder and it worked.

Hi,dump opens in tango 16bit. What do you need?

Ok, since AVDI won't program a transponder because it can't recogize the dump but 4C is a fixed one is there a possibility to Insert this is300 4c.jpg
into the dump as KEY 0 / Master Key. then i can write dump back to 93c56
