Here we share one of our customers’ working experience on programming a Toyota Yaris 20019 all keys lost.
It’s blade key Toy47 4D type.
This one no way by obd. Read eeprom and add the key by dump mode.
Eeprom only, you’ve done the hard part getting the box out, read 8 leg, write back and plug in to start.
Did the eeprom, removed the atmel chip, and read the eeprom, he took an Xhorse super chip XT27A transponder and generated one of 2 keys that was in the system, and then wrote back eeprom to the chip, and solder it back, but the car won’t start.
Then also tried XT27B chip, still no lock.
Updated:
He did all with VVDI XT57B super chip.
It didn’t work 1st time , but after 2 attempts all worked as it should.
Tried without writing back eeprom after generating the key, didn’t start.
Wrote it back and it worked.
FYI:
There are two similar boxes. The immo box is very good hidden.
Whole dash has to be removed for the correct immo box.
