In most cases the yellowing of a cellulose key will permeate the whole key. In your case it just might be from the acid in the fingers of a previous owner. Try auto buffing compound. You might also refer to past posts here on this subject. As for leveling a keyboard - go here and give a read --

These hints & tips are scanned from my READER'S DIGEST book 'Extraordinary uses for ordinary things.'
Remove yellow stains from piano keys Although your old piano still plays beautifully, its yellowed keys may be showing their age. Remove stains by mixing a solution of 50g bicarbonate of soda in 1 litre warm water. Apply to each key with a dampened cloth (you can place a thin piece of cardboard between the keys to avoid seepage). Wipe again with a cloth dampened with plain water and then buff dry with a clean cloth. (You can also clean piano keys using lemon juice and salt.)
. If the keys on the piano are starting to yellow, apply a little mayonnaise with a soft cloth. Wait a few minutes, wipe with a damp cloth, and the piano keys will look like new.
Clean piano keys Whether it is a baby grand piano that fills the corner of the living room, a more conventional upright or just a fold-away electronic keyboard, cleaning the keys can be a nightmare project of dust and finger marks. And when you clean it, it is hard to reach some spots to remove dirt. The sides of the black keys are especially difficult to clean. Find an eraser that fits between the ivories and the black keys and simply rub away the ingrained dirt. This works as well whether you have a piano with real ivory keys or the more common plastic ones.
Clean piano keys Has too much tickling of the ivories left them a bit dingy? Clean them up with toothpaste and a toothbrush, and then wipe them down with a damp cloth. Toothpaste will work just as well on modern pianos that have keys made of plastic rather than real ivory.
Clean piano keys Here is an easy and efficient way to get grimy fingerprints and stains off piano keys. Dip a soft cloth into a solution of 100ml white vinegar mixed in 400ml water, squeeze it out until there are no drips, then gently wipe off each key. Use a second cloth to dry off the keys as you move along, and then leave the keyboard uncovered for 24 hours.

Yellowing keys is not really a problem, just play it.
Keys which are not level are not a problem for a trained repairer. but an amateur can easily crack the wax/resin which joins them to the pallets, or bend the rods so that the pallet the seal is imperfect, I have had limited success trying this repair.

Thanks, I don't know the other methods but this is what I used when restoring Jukebox plastics years ago.
I used wet sand paper 340 grit. Wet and sand the yellow ends only one at a time. this step 30 to 60 mins total. After all is done sand each with 600 wet sand paper. Maybe 30-40 mins. Didn't do this yet. After this plastic polish should do it. An hour for this. You can just stay as in the pic but you won't have a shine on the sanded areas. You don't want to drown the accordion just a drop of water as you work. Ron

Big improvement - well done. I think as Jim said, you're kinda fortunate the yellowing is caused by greasy fingers/ hand acidity. If the yellowing had been cause by lengthy exposure to UV light, it would go all the way along the key and right through the plastic...and likely would not polish off at all.
Looks loads better. :tup:

Thanks all \
Now I have to take the cover off, the side with the keys, to adjust a couple key heights. I guess remove the 4 screws and the screws over the registers and take it off. Ron
