The entire concept of a key signature is that all the chords in that key are built from the notes of one particular scale. If you want to use a chord that isn't in the key, or a series of notes that aren't, then you alter or adjust the scale you are using to incorporate that chord or those notes.
I don't know what your knowledge or skill level is. With that in mind you might want to have a look at these tutorials on the basic relationship between scales & chords.
