I got the keys from Kate but I can't press on the map and the hint says something about I need to have a gun and I'm guessing I need to buy it but I can't press on the map
To open the map, you must be outside the house. When you exit the MC bedroom, check for a door on the right side, at the end of the corridor(you can miss it very easily if you don't know it is there). Enjoy!
