Question 1: Did you have all doors, hood and hatch closed and try the unlocking thing?
Answer: Yes.
Question 2: Speed of flashing light.
Answer: Very slow. Flash, pause flash pause flash pause. Horn does not honk when I use the key to unlock it either.
Key fob is not communicating with the vehicle, I guess, because the little light on the key fob lights up, but the vehicle won't listen to it.

Is the batter fully charged in the vehicle, or are you trying to start it via jumpstarting?
It takes a few minutes for the BCU/IDM to sync up (without any special equipment needed) after reconnecting the battery.
Turn the key on and come back in a half hour and see if you can start the car. If not try to disarm the car by unlocking the door and try starting again.

The IDM communicates with the BCU and the instrument pack via a serial interface. If the BCU or the IDM is replaced, the communications link between the two units has to be re-established. This can be done either by switching on the ignition and leaving it on for five minutes, or by using TestBook. The vehicle immobilisation will remain active until the

New battery. Left it on on for 30 minutes, tried everything again, still no dice. It just left on a rollback to the dealership for them to try and sync it only, not replace the bcu. If they're unable to resync, I will put a used bcu in and then have them resync it. 
I will let you guys know how it works out.
