So after some late nights and a lot of browsing through old forum threads, I found out that the receiver isn't coded like the key and ECU. What I did after was I plugged the new barrel into my car, so the receiver works. Inserted my original key, so not the new one I got with the barrel. Left my broken barrel alone and just turned the car over with pliers. She fired straight away, after a month of sitting.
What I need to do now is rekey my new barrel, to accept the old key. At least I don't have to pay to have the car reprogrammed. Here's some pictures of the ongoing process.
New barrel.
All the pieces of my old barrel I saved.
Receiver removed.
This pin came out with tweezers.
Out the lock came.
Salvaging the tumblers from the old lock.
Hit a snag where these pins need to be hammered out, in order to slide the tumbler assembly out.
I'm currently stuck now because I don't have the correct tool. Its a 1.5mm punch I need.
