I Need PIN Code For Opel Vectra-C

Hi,

I've replace fuel pump and CIM on my Vectra but the immobilizer was active now, i don't know why, i want to try to reprogramm the key but i need the security code and/or the PIN code.
I have an OP-COM 2014, i don't know if i can read the PIN code somewhere with this tool...
VIN: W0L0ZCF6848005108

If someone could help me with this car.
Many thanks in advance!
Best Regards.
Cedric
