    Hello Prius C fellows, I need to pick your brains with an issue I have.
    I have an issue with my 2013 Prius C TPMS computer, I started to have issues with one of the rear sensors losing connection and getting the light on the dashboard, like and idiot instead of researching more I pressed the reset button under the steering wheel and did nothing but locking the TPMS computer.
    I got a new TPMS sensor for the wheel but now I can t program it because the TPMS computer is locked and needs to be unlocked, I tried with Autel Maxi TS508 but can t program the TPMS because the computer is locked, when I say computer I refer to the TPMS one.
    I went to my mechanic and his fancy $5000 Autel MaxiSYS tool can t unlock it, does anybody has any ideea how to unlock it or what tool to use ( I have Techstream but does not have any option to unlock TPMS computer).
    Thank you.
