Loki's Lost Key is an addon for the ArmA 2 series of games. When it's used in conjunction with DaiZy (the single player mod of DayZ), it adds a bucket-load of features and cheats.
If you haven't installed DaiZy, then I've no idea why you're reading this. Head on over to this article first:
Before you install Loki's Lost Key, you're going to have to install the CBA addons. These are just a series of little addons that make it easier for other people to write other mods and addons. Loki's Lost Key uses them, so you're going to have to install them.
Go here and download the file (download link at the bottom of the page):
Once you've downloaded the file (it's very small), open it in whatever you use to open 7zip files (I'm using WinRar). There's one folder inside. Extract it to wherever you like.
Take that folder and copy it into your Operation Arrowhead program folder.
C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowheadIf you're not using Steam, it's probably in:
C:\Program Files (x86)\Bohemia Interactive\Arma 2 operation arrowhead
Once you've pasted those folders, you need to tell the game to use them. This is done by modifying the game shortcut to include the following:
-mod=@CBA_COOkay, so that's the CBA addons installed. You're now going to install Loki's Lost Key and I promise it'll be easy.
Open the loki_lost_key.7z file in your favourite archiver (I'm still using WinRar). Extract the folder inside to anywhere you like.
Inside you'll find two folders: addons and holomap. Quite honestly, you can ignore the holomap. It's a fancy useless map that you'll never use; it creates a 3D object inside the game and (very slowly) renders a holographic map on top of it.
Inside your Operation Arrowhead program folder, you should make a new folder and make another new folder inside that. Just as you made an @DaiZy folder when installing the single player mod in the first place, so you should make a new folder beside it called @LostKey and create a folder inside that called Addons.
That sounds a little complicated. It should look like this:
Where OA is your Operation Arrowhead program folder.
Take the loki_lost_key.pbo file and place it in that folder, just as it is in the screenshot above.
Now you need to modify your game shortcut to load Lost Key. Just as you added ;@CBA_CO to load the CBA addons, so you should add ;@LostKey to the shortcut. Make sure there is a semi-colon(;) between each item.
And that's it done. The nice thing about using this installation method (called modfolders) is that Lost Key is only loaded when called by the shortcut. When you play normal DayZ online, it won't load Lost Key, so you can be sure it won't cause any problems.
When you load DaiZy, you'll see in the centre of the screen some light blue text saying Lost Key. If you don't, that means you haven't installed it correctly. Now, assuming that you do, you can use the mousewheel menu to bring up the main Lost Key interface.
This is the main interface. Although there are a lot of headings on the left, the main ones you're going to want to use are under the section marked Work.
You'll be able to guess what a lot of the selections do just from the name. Note that the map shown is used for some of the features. You can drag the map around by holding down the right mouse button and zoom in and out with the mousewheel.
The Magick and Mischief sections contain settings related to god mode and healing. The way that DayZ and DaiZy handle health is different from most ArmA 2 mods, so many of them won't work or won't work in the way that you'd like.
This is the weapon selector. It will make available any weapon from ArmA 2 and Operation Arrowhead, not just the DayZ guns.
Loki's Lost Key has so many options and features that it's impossible to detail them all, so just explore and have fun.
