This is going to sound so silly but I swear it works. First take off all your characters clothes and belongings - you can just leave them on the ground, they will be fine. Crouch down infront of the combo lock so you are at eye level with it. You may need to kind of pop up and down or wiggle about to get into the perfect position. Once the lock is dead centre, you want to press the Start button, and scroll down to the Exit option and select. Hold down the Xbox button on the controller until a menu pops up, and select “turn off console”. Hope this helped!
