How do I open the barn door?
 

The part where Kenny and Lee go and check on Danny, I forgot how to open the door on the PC VERSION!

A or left arrow key.

Wrong forum. Just click on the door.

simple there is a tool box near the genrater with a multitool use the mutlitool to fiddle with the genrater and then go in the barn and use the multitool and use the multitool to unscrew the lock on the door in the barn

Open the toolbox outside, grab the multitool, open the generator, turn off the generator, remove part of the generator with the multitool, leave the generator, let Andy try to fix the generator, enter the barn, use the multitool to unscrew the nails in the door lock, and then open the door.
