A coordinate system has a zero point and a number of axes, which are somehow normed and defined.

 Taking it short - coordinates are tools, designed mainly
to locate things, and, just like other tools, con work
in some cases and can't work in some other cases.
 

Well, more or less.
Coordinate systems are man-made constructs and only imaginary.
The points in space are actually real, but carry no tags (or similar) which tell the coordinates.
Sinse the points don't know where they are, we can measure their location only in repect to something else.
This 'something else' is what we usually use to define a coordinate system.
