Stuck BlackPlague chemical room dark kennel code card.

Spoiler below!

Go to the room on the right. There's a control panel that turns some lights on and some off. Unfortunately the control panel turns the lights in the corridor leading to the room on the right off. Block the holes in the wall with boxes that are in the room at the beginning of the corridor so dogs don't come out and attack you while the lights are off.
