Immobilizer Code Reset Failed (Smart Key Reset)

Long story short, I have 2005 prius with SKS and I lost the last fob, after a little research I decided to reset the immobilizer (to delete all connected keys to this car) and register a different used key from another prius. I found a third party with pass-code calculator (5 tokens for 25$) but my problem is whenever I try to start this 16 minute reset process I have a fail. This happens because I don't have any keys and I can't start the car (OG - On, one click to the push button) and because of that I can't connect to the immobilizer and reset anything. Does anyone have any suggestions?

 

Yes, I'm doing this via a Techstream. I don't think a Window is the problem. Unfortunately I'm don't know any locksmith who works with Toyota's or Techstream. It fails right after I put the passcode and press next, there is a notification about that resetting can take about 16 minutes and when I press 'OK' I have the same thing as on a picture. The Driver door is open, the immobilizer is flashing (so it works) but because the power is not ON i can't procced forward.
