I would use master key for first two parts dont think it matters to be honest departs if they both start car and it won't change key code as that part is wireless ecu

In order of RED's:

MASTER - This gives the ECU a known key to let it know it is authorised

NEW ONE - This is inserting the key that is to be programmed

NEW ONE - This is telling the ECU to read the new key's code and add it to its database of authorized keys

Just be aware that trying to program the immobilizer with a used key can be hit or miss.
