fitting parts from other vauxhalls

I use SPS via the tech2 J2534 thing... it's slow but seems to allow programming... untill it moans of the hardware mismatch...  but i'd imagine even GDS2 would do that  (GDS2 dosent cover the Meriva B untill after the 2015 model year anyway, mines a 2011)

atatched are 3 dumps of the insignias eeprom, its a 24C16 eeprom, 

The original one is what i dumped off it before i changed anything... BUT i'd been driving around with the ipc in my car, and that had the odometer lock triggered, 

I then altered the eeprom data, to have my chassis number and security code, that's all i changed, i then did a program of the BCM, which removed the odometer lock, and the mileage showed then.. but still the 2 nag screens and airbag and engine light on. 

I then tried to program the IPC, and it refused due to hardware mismatch, but i have just poped the eeprom off the board, read it and it's different again.... thats the dump with 'something not right' 

the security code seems to be missing.... 

i have for now put my original ipc back in the car, and that is bringing up a DTC for imobilizer mismatch, but the car starts and runs fine, i tried to divorce it to add it again, but it failed saying security code not right... so i will have to take that ipc appart and read the eeprom again, to see if that too is missing the security code like the insignias one is.... 

Should i be able to give it a new security code with tech2?
