Before we begin, you will need 2 controllers! If you don't have 2 controllers it will not work. Also you WILL NOT get the golden keys for your main account.

Step 1: Disconnect the console from Xbox Live.
Step 2: Go to sytem memory in settings, and on both your HDD, and your USB Flash Drive you want to clear cache. This will remove all patches on Borderlands 2.
Step 3: Create a brand new account, do not connect to LIVE! It doesn't matter what the name is or anything like that I named mine "Golden Key".
Step 4: Sign into your second account, and play Borderlands 2. Start a new character, whenever you are able to save and quit do so.
Step 5: Quit Borderlands 2, return to the dashboard.
Step 6: Move your main account, second account, and the save game of your main account you want the golden keys for.
Step 7: Move to your PC, and plug in the Flash Drive.
Step 8: Open Horizon 360.
Step 9: In Horizon pull up your Main account and your second account.
Step 10: Go to the second account's "contents" tab, you should see a "5454087C.gpd" file. Right click on it and choose replace, a window will open asking for the file you want to replace with. Find where you downloaded the modded GPD to, and hit open. Save, rehash, and resign.
Step 11: On your second account in the bottom left click manage, a profile manager will open. Check the box beside favorite, and hit the "X" in the top right corner of the Proifle Manager. Exit your second account.
Step 12: On the right Open the Device explorer if it's not already open. Drag and drop your Borderlands 2 save of your main account onto the desktop by opening games then Borderlands 2.
Step 13: Change the file name from "Save0001.sav" to "Save0002.sav"
Step 14: Drag the save back into Horizon, in the bottom right corner click "change", and choose your second profile. Save. Rehash, and Resign. IF YOU GET THE ERROR MESSAGE " ........ already exists on this device do you want to continue?" or something of that nature DO NOT CLICK continue. Go back and change the "Save0002.sav" to "Save0003.sav" If you get the same error message continue changing the last digit of the 4 number code until it works.
Step 15: Check the Device Explorer to make sure 2 savegames now exist, they should only have one change, one should have your main profiles name, and the other should have your second profiles name.
Step 16: Exit Horizon, unplug the Flash Drive from your computer, and plug it into your Xbox.
[b]Step 17: Now on your Xbox, turn on both controller's. On controller one sign into your main account, on controller 2 sign into your second account which you modded.
Step 18: Start Borderlands 2, disconnected from LIVE. Choose your Flash Drive when prompted at the memory page.
Step 19: On your 2nd controller, join the game and choose the character you have on your 1st controller. There should only be one character so process of elimination.
Step 20: Start the game, and you should get the message " You have 255 Golden keys....... etc. etc.......
Step 21: Once in game on your second controller open the chest, and on your first controller take the items.
Step 22: When you feel you have what you want, simply leave the game on your second controller. Sign out your second account, reconnect whatever you use for Xbox LIVE, and sign into LIVE.
Step 23: Whenever you use all 255 Golden Keys, just replace the GPD and continue.


Have Fun!
