Borderlands 2 Glitches

Workaround for Golden Key Patch (PC ONLY)
In one of the first post-release patches, Gearbox has blocked the well-known infinite Golden Key exploit. There is a solution for this.

NOTE: If you are playing as a Mechromancer, create a character as another class before starting this. You will be temporarily downgrading your game to the initial version, which will make your Mechromancer unplayable UNTIL you upgrade back to the current version. Don't worry, after you re-upgrade, it'll work again just fine.

1) Uninstall the game completely but do NOT delete your user data.

2) Reinstall the base game. Do NOT install any DLC or updates yet.

3) Perform the Golden Keys edit to the WillowDLC.ini file as already posted here.

4) Open the game, load any character (again, not a Mechromancer), then save and quit.

5) Reinstall all the patches and DLC you have back up to the current version.

6) Go to your user data folder for Borderlands 2. This is either C:\Documents and Settings\<username>\My Documents\My Games\Borderlands 2\WillowGame\SaveData\<random string="string" of="of" numbers="numbers">\ for Windows XP, or else C:\Users\<username>\My Documents\My Games\Borderlands 2\WillowGame\SaveData\<random string="string" of="of" numbers="numbers">\ for Windows 7.

7) Copy the file profile.bin to your desktop or somewhere else. (NOTE: The old trick was to set this file as "read only" but this has been patched, which is why this whole process is now needed.)

8) Enter the game and use up all the Golden Keys continually looting the chest in Sanctuary. Sell whatever gear you won't or can't use whenever you run out of backpack/bank space but just keep looting the chest until you use up all of your keys. When you run out, save and quit.

9) Copy the profile.bin file from your desktop back to the folder you opened earlier, overwriting the file in the user data folder.

10) Reopen the game and notice all your keys are back. Save and quit again.

11) Repeat steps 7 through 10 as many times as needed until you're satisfied with the massive backpack full of loot you've acquired.

This cheat can be re-used indefinitely. However, if you do this, make certain you recopy your profile.bin file each time you want to go through the process again. This profile.bin file not only saves your number of golden keys, but also other things, including your badass rank. If you don't save a new profile.bin file every time you do this, overwriting it with an older version will wipe out all of your badass points and badass rank!</random></username></random></username>
