To use these cheats, you must first buy them from the DLC center. To get there, you can search for Saints Row IV on the XBOX 360 dashboard, or alternatively, load Saints Row IV and go to the main menu. Once at the Main Menu, select "Downloadable Content". Then select "All Downloadable Content". The DLC pack you want is "Executive Privelege Pack", which costs 160 Microsoft Points (Equivalent to $2 USD). After the pack is installed, you will receive a message in the game telling you it was installed. Simply go to your phone and select "Extras", then "Cheats", then "Add Cheat". You can now use the codes below.
