year 2003 this kind of key

I can't program the remote with sbb or alfaobd bcose the pin is wrong. They have the original keycard. And according the alfaowners forum the remote and the immobox are seprated and they are using different pincodes.
The codecard contains only the immo and the mechanical code. If this separted pin thing is real there is any solution to read the remote pin code (obd or with soldering job) or any alternative solution to program the remote w/o pincode?
thx
