2005 Touareg Key Copying Fault

[TERMINATOR1000]

Seems hit and miss. I tried by myself and not work. In 'best' situation the steering lock was unlocking with 3 seconds delay after putting the key, car started and engine stopped after 1 second.

ISK change after every start engine , in pcf 7946 process it's OK but not in CN3 ....

The result is simple , cloning is impossible ! Only programming ....
