    Good morning,

    I'm having issues with my Toyota Prius 2012 not starting. This morning i drove my Prius to work and on my lunch break i went to go to start it back up and unfortunately its not turning on but I'm getting power to the car. The key fob is good, recently swapped out the small battery. Green light pops up on the circle power button near the steering wheel but it doesn't turn online. I also have issues with my hybrid system, I recently swapped out the battery pack for a pre-owned battery pack cause i was receiving a "Replace battery pack" Code and this code is still occurring even after replace the battery pack. Now would the hybrid system issues cause my car from not turning on or would this be a 12V battery issue. Once i get off work im going to try to troubleshooting the 12V battery and do a "Reset"

    What "small battery" are writing about? Did you mean the 12v battery?
    Did you Charge the 12v battery? The stores do not.

    What tests did you perform to confirm the hybrid battery actually did need to be replaced?
    What tests did you perform to confirm the "used" hybrid battery wasn't bad?

    You will have to clear the codes with techstream or similar diagnoses tool.
    Are you CERTAIN you installed the orange safety switch correctly? Would hurt to remove it
    and reinstall it, just to make sure.
