Car wouldn't start ... but I fixed it!

Nah actually that works great. You can also use the same setup to get the back door open, and then use that improved access afterwards.

 

There is a jump point under the hood. It's not so exclusive. Everybody has one with a Prius of this generation. You can charge or jump from there. You access the car with the mechanical key hidden inside your key fob and then access the hood with the mechanical lever inside the car. At that point you remove the top of the engine fuse box, it will be on the driver side, flip open a red cover on the jump point and use positive there. Connect negative on an any nearby metal piece.

Realize a completely dead 12 V battery may take may take a period of time to equalize with the jump power source. Normally, this is not a problem or a concern.

A significant issue with jumping in the front or the back is a reverse polarity connection even for a few seconds.
It will blow a nearly inaccessible 125a fuse buried in the middle of the engine fuse box. Along with various other fuses that are easier to access. Which makes the next subject a near must have regardless if you are getting a jump or you are giving a jump.

A small lithium jump pack stored under the driver seat makes the whole process a one man job especially if you can start the car right away. These boxes have polarity verification circuitry used before they apply power.
