If you don't want keylight to do any color correction then set it to intermediate result in the view options.

I suspect a poorly-shot green screen. It's easy to make a mistake if don't have green screen shooting experience. Please show us a still of your un-keyed shot.

That looks good. You should be able to pull a good key from that image. Does the key look good in Keylight's Status view? You should see black in the green parts, white on the subjects and gray at the edges.

I would look over training materials for Keylight, because there is no reason you can not pull a good key.

Yellow is a bad candidate for keylight. If you can't get a decent matte (check
Screen matte view and status view), I would recommend using Primatte which is a 3rd party keyer by redgiant. It uses a different technology than keylight and it is especially useful with different colors than the normal chroma backgrounds that keylight excels is (red, green and blue).

Optically, yellow on green screen is similar to pink on blue screen - they are much harder to separate (yellow light is made of red and GREEN light and pink is made of red and BLUE light, so there is a lot of the screen color hidden in those seemingly harmless colors). Primatte, as Roei pointed out, and Ultimatte do a better job with these problems than Keylight. Determining ideal screen color is based on many factors including foreground colors, but in this case with both pink and yellow characters neither green or blue screens would solve everything.

Try pulling two mattes - do a rough roto around the offending yellow elements and key that with one set of settings (a little harsher) and key the rest with another (its a good screen color so you won't have to go too far off the defaults to get a good key). Try also not letting keylight do your screen color suppression for the yellow areas (at least on the matte pass)
