Find the light board, pictured below:
Once you are at the light board, turn on your flashlight, such as the one on most smartphones and then turn down the dimmer control number 24, pictured below:
Once these house lights are off, the studio will be completely dark. Make sure you use your flashlight to make your way over to the door. If the studio door is open, a firm push to close the door, which is heavy, will automatically lock the studio. If you are using the pedestrian door, please note that there are stairs leading to the door. You will need the key to turn the lock from the outside.
