With the key?
How do you open the trunk in a 2010 toyota Pirus if dead battry
Surely there is a place to insert and use a key to open the trunk.
Use the key
Use you key.
use the key
With your key.
Remove the rear seat.
Replace the battery or jump the battery.
How about hooking up jumper cables, which can be done under the hood, and let the alternator of the charging vehicle provide the unlocking power? Use the metal key that slides out of your keyless remote if it has one and unlock the trunk manually where the release button is on the trunk. That's how it is on my e320 if it's the same.
Put your key in the trunk lock and turn.
1. you can pry it open (but that can get costly). 2. you could jump start the battery. 3.use your key.
