[REQUEST] How to make several keys in on map

[Khan]

kk, so I have a key already, but, I dont know to make another key, can anyone help me here? lol. Here is wat my .hps looks like.

////////////////////////////
// Run when entering map
void OnEnter()
{
AddUseItemCallback("", "chamberkey", "chamberdoor", "FUNCTION", true);
AddEntityCollideCallback("Player", "script_slam", "func_slam", true, 1);
AddEntityCollideCallback("Player" , "doorbreak" , "MonsterFunc1" , true , 1);
AddEntityCollideCallback("Player", "doorslamtrigger1", "Func01", true, 1);
}
void FUNCTION(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("chamberdoor", false, true);
PlaySoundAtEntity("", "unlock_door", "door1", 0, false);
RemoveItem("chamberkey");
SetSwingDoorClosed("doorslam", true, true);
SetSwingDoorClosed("doorslam2", true, true);


As you can see, I have a key already, but I dont know how to make another, I cut off part of the script as to hide the other, surprises, in my custom story. any ideas?
