Door latch bollt question

[RandallNeighbour]

I'm trying to replace my door latch assembly and what I thought was a 45mm torx head is something else I do not own. It has twice as many points as a torx bolt head.

The Bentley manual says "remove bolts" but does not indicate what tools I need.

Can someone tell me what I need to remove the two bolts that are on the exposed, painted part of the door (not on the inside of the panel). And if you know what it's called, where could I buy one tomorrow (Sunday) so I can wrap up this project?

I sure hope this isn't a special Porsche tool I have to order. That will be expensive and cause even more delays. Without this part, I cannot lock my car and thus, I can't drive it and park it anywhere.

I've attached a rather crappy iPhone pic ...
