Wheel security nut

I recently bought another 45td, ten years old and quite a good buy. However, looking at the tyres it won't be too long before they need replacing. As normal, each wheel has a security nut. These are a sort of female star shaped thing - a bit like this, but I'm not sure if this is exactly the same thing: http://ift.tt/1FfaiBI



The spare wheel is of the space-saver type, and looks to be brand new. The tool holder was actually shrink wrapped and looks as if it's never been used. In there is the usual jack and wheel brace, but there is also a small compartment that looks like it should contain the key for the security nuts, but there's nothing there! Clearly I've got a spot of bother here if I have a puncture, or go to get the tyres replaced. Does anyone know if this is a standard Rover security key and, if so, any ideas where I can get one from?
