Toyota Avensis 2004 24C04 AKL with VVDI Key Tool Max Pro

 I am working on with Toyota Avensis 2004 (EU) all keys lost and found immobox 89780-05040.

 

Finally i got it working. Solution for whole thing:

1. Remove Immobox behind center vent on the dashboard.

2. Read eeprom 24C04 with VVDI Prog Clamp

3. Use VVDI Key Tool Max Pro Immo data -> Add ID70 transponder to eeprom file (USED Old junk avenis original 4D transponder!)

4. Write new file back to eeprom with VVDI Prog

5. Plug it back to car

6. Cloned chip to new key

7. Start car wtihout problem!

So as result original 4D chip is critical. I dont understand why i can still clone that chip to superchip and it works also.

This car need original transponder. Super chip no good.
