I have the code entered right for the gray door in the awakening desk room but it doesn't blink and..

There is a red box, where is a srewdriver and a wire, use the wire to fix the lamp atthe desk, then you see the letter codes, which might be different for you, so you should write it down, then if you have the hammer and the flashlight, break the white wall (in the room where is the desk) and use the flashlight so you can see what each letters equal to. Write that number in the order of the letters in the safe, in the kitchen, then there should be a paper which is the code to the gray door, check it multiple times to see if you selected the same letters to the specific position.
