How do I open a door with a crowbar?

[flamez3]

AddUseItemCallback("", "crowbar_1", "prison_locked", "UnlockDoor", true);
AddEntityCollideCallback("crowbar_joint_1", "door_script_1", "crowbarfunc", true, 1);
}
void UnlockDoor(string &in asItem, string &in asEntity)
{
SetEntityActive("crowbar_joint_1", true);
//SetSwingDoorLocked("prison_locked", false, true);
//PlaySoundAtEntity("", "unlock_door", "prison_locked", 0, false);
RemoveItem("crowbar_1");
}
void crowbarfunc(string &in asParent, string &in asChild, int alState)
{
SetPropHealth("prison_locked", 0.0f);
SetEntityActive("crowbar_joint_1", false);
SetEntityActive("crowbar_dyn_1", true);
//PlaySoundAtEntity("", "unlock_door", "prison_locked", 0, false);

}





And the doors name is prison_locked and the crowbars: crowbar_dyn_1 and crowbar_joint_1

I'm new to scripting so dont laugh if I failed hard hahah.

What's the name to the crowbar item?
