How do you open the trunk in a 2010 toyota Pirus if dead battry
Use you key.
Use the key
With the key?
BMW's have auto-locks a little different from other cars, if your battery is dead, the doors won't open. To change the battery, you need to open the trunk, this is where the battery is located. You will see a panel with some screws, you need to remove that and underneath is the battery.
Surely there is a place to insert and use a key to open the trunk.
With your key.
