Put in any combination then press OK. The code will be wrong, and it will cause an agent will come out to check the area. When the agent turns around, use clairvoyance on him. He will input the code to open the door, which you can now see through his eyes. The code is a random four digit number that changes with each play though. Use the keypad again and input the code you just saw.
