Door lock script that the owner can designate to a group?

Ok I saw a couple of the door lock scripts that are in the library but I need one that I can put on a rental property and allow them control over the locking and unlocking.

In other words, I need one that I can designate to them so I don't have to flap my wings to the house everytime they want to have someone new come over.

Anyone know of one?

Thanks

Simple, use llDetectedGroup(integer num) or llSameGroup(key id)

Say you allow locking/unlocking on a touch event (pretty normal)

// globals...
g_nLocked;

//....

default
{
  state_entry()
  {
    // unlock door (default "startup routines)...
    g_nLocked = FALSE;
  }
  touch_end(integer num)
  {
    key whoid = llDetectedKey(0);
    if (llSameGroup(whoid))
    {
      if (g_nLocked)
      {
        g_nLocked = FALSE;
        // unlock door routines...
      }
      else
      {
        g_nLocked = TRUE;
        // lock door routines...
      }
    }
  }
}

Edit php encoding looked like doodoo
