Go up the elevator.

Go into room 1, get a cigarette lighter from the table and 2 hip flasks from the nightstand on the right wall.

Go into room 2 to get some things.

Get sandalwood oil from the shelf in the back-left.

Go to the table and combine the following (smash E):
Hip flask + oil = explosive mixture
explosive mixture + rag = sandalwood bomb

Go to the right and use the hip flask on Sundew to knock it out.

Try to open door 4 and you'll need something to open it. Use the bomb. Then use the lighter on the bomb.
Go to the desk on the right and open the drawer. Minigame for the electronic lock - dodge the red lasers. And remember you can move up/down and not just left/right. Grats, you get a key.

Now open door #3.
