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.

David. Unfortunately for you I have found that key (it was laying on the ground) and didn't proceed with reseting. The best you can do is to find someone who makes keys, or look more into advanced tools for this job. I remember looking at scanners for $1000-2000 + other devices, that can do this job, but unless you're planning you continue working with making keys, you're best way is to pay that $300 for a new key one. Techstream didn't worked for me and I still have that 5 tokens.

 

Correct. That car got into an accident + ABS module failed (bleeding or calibration didn't help, it was to late). So I just sold it because didn't want to invest into it anymore.

 

I got stuck at the same place. I bought tokens, everything works but after short moment immobilizer code reset fails. I didn't found a way and just wanted to pay for that key.
