NO POWER AT ALL, not even able to lock or unlock doors

We have ZERO power. At about 156,000. We are timely on maintenance and recalls. Nothing is working. We aren't even able to lock it or unlock it. HELP!

 

We "fixed it" using the first of these methods. Whew!
Method 1 of 4: Restarting your Prius
Occasionally, a Prius will just refuse to start normally. This is the result of some sort of power failure that is preventing the car’s computer from booting. If you find yourself unable to start your Prius, you may just need to reboot the computer, similar to when your computer freezes and you have to power it down and then restart it.



Step 1: Press and hold the “Start” button. Hold the Start button down with your index finger for at least 45 seconds.



Step 2: Restart the car. Start the car normally after the system has rebooted by pushing down on the brake and pressing the Start button again.

• Tip: If you try to restart your Prius and the dashboard lights come on but they are dim and blinking, you may have a problem with your 12V battery. If this is the case, the battery may need to be replaced or jump started (see Method 2).
