Used Xhorse VVDI Key Tool Plus to program 2011 Porsche Cayenne All Lost Key, take about 25 mins in total!

Prepare Porsche BCM adapter XDNP17, which I already put it on the board.


VVDI Key Tool Plus read D-FLASH successfully, and tick off "Save and edit" and then "OK".






Back to tap "immo programming", then select "Europe" and "Porsche", then "New Porsche key-generate dealer key", tap "Start Programming".



Tap "Generated key", then "EEPROM (5M48H)".



Tap "OK" to load the EEPROM data.

Select "Key 4".

It prompts "Don't detect transponder. Please input key first!".


After putting key first, tap "Generated key", then "EEPROM (5M48H)", then tap "OK" to load the EEPROM data.
Select "Key 4" to make key.

Click "OK" to save new eeprom data.


Generated key successfully. Just refresh the newly saved file to the car. You can also learn the new key to the car via OBD!

If you want to add new key, please use the newly saved file to generate.


Job is done!
