    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?

    Sounds like the reseeding process after the wiping clean of the system is where it's failing. Assuming you're doing this with Techstream? Maybe try a different Windows computer? Or maybe ask an electronic locksmith who does this work?

    Seems there should be a process during the wipe & reseed where the new FOBs are registered into the system? Is it failing before you get to that step?

    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.

    Prius Lost All Keys SKS Smart Reset (Program Used Fob) I was following after this instruction.
