Toyota aqua 2014 flooded need some help

Hello I have a 2014 Toyota aqua that was flooded and all the computers in the car was destroyed. I have replaced all with the same part numbers from Japan and now that car seems to have life. I can get in ignition but some times it would turn off automatically and then back on. all the computers that I have changed were the computer multiplex body(fuse box), smart key and the power management control. Also when I unplug the smart key computer the car stays on ignition and doesn't turn off automatically. Could it be a bad smart key computer that is causing it to turn off. I also had a locksmith come to reprogram the computers but he was unable to get it to work. I also have a hybrid system warning light, I have not fan on the hybrid battery and no abs computer. Could that cause the light and prevent the car from being programmed. Please any help would be appreciated I don't want to buy parts that I already have only I know it is faulty I would have to.

 

Update the car is turning on ignition and won't start. There is a flashing lock symbol in the bottom left corner could that mean the car is still lock

 

No I ordered the cable I'm still waiting for it to arrive. My question is when you replace all the computers in the car would it need to be reprogram to communicate with each other ? And can it be done with the Toyota techstream software ?
