Stripped Bolt - Help

Just bought some new rear brake pads for my 2010 ninja 250. Went to remove the old ones and noted that one bolt (which is flush with the caliper) was partially stripped. I tried removing it with the correct allen key but cannot get it out and don't want to make it worse (I know I used the correct allen key the first time since all the other bolts came out with no issues).

Any suggestions on how to remove it? I have already tried using an elastic band at the end of the allen key but no luck. I'll obviously replace it with a new one once removed.....if I can ever get it out.:x

EDIT: Posted a pic below. You can see the three removed and the one left.

Get a screw extractor at CT.

get a hammer and tap in a slightly larger torxs (*sp) bit into it.
The bit that looks like an allen but has more tiny ends like a star.

I would suggest trying to spray some wd40 or any thin oil that you can get into it.
That bolt should come out.
 
All fixed. Tried one more option before taking drastic measures. Tried the allen key that came with the bike :( apparently it must be a custom size and "barely" worked. Well...this is embarrassing.

Its not special, its a regular 5mm allen brake pad pin....

You were likely using an imperial sized allen key the first time. May have looked like the right size, but it wasnt.
