If i ever become a mechanic i would want to do things like this. I can't imagine how much knowledge and dedication you need to do this. I want more of it. Side note imagine if aliens are real and this is how fast they think we can move. That would be funny.
To sort thru this , you need to do a global scan 1st to see which modules are up(awake) and which ones are down. If all security related modules are up AND you actually replaced ALL modules then you should simply be able to reset security with a decent key tool thru OBD. I suspect you have a key module that is down( no power,ground or bus fault). Also the cluster is part of security on many Global A vehicles, did you replace cluster as well?
Imagine this gentleman just show up at your location and you know that you are going to have good week Make sure close the door before signing the deal so no customer can spoil your deal. Don't tell the price , just ask him to make his own price😂، so far it look will be higher than your asking price Sorry Sound your first deal , but no worry , you learn for next time Don't do it again 😂 U could paid for full trucks with no accident history or lemon law for same price
