DETECTIVE - The Motel

The keypad (for room #5 I think) is tied to the drawing above the keypad. You need to look through the window to find items that are located where the drawing shows.
First item is a red playing card #7
2nd item is a picture of birds #2
Third item is a blinking light on the back wall. It blinks three times so #3
Last item is the picture on the right of the room with the #5

So it's 7, 2, 3, 5 to open the keypad and get the achievement.

The other achievement (Turin) tied to getting in this room is picking up keys and unlocking the green truck right outside of the room. There are supposed to be keys on the desk when you walk into the room by the model ship but they were not there for me. I had to restart the game and then I went straight to the room and the keys were there. Unlocked the car and achievement popped.

Hope this helps you guys out! K148 Game Studio came in clutch with help on this one.
