There are several programs that can interfere with the use of the shift key and several other keys, like certain versions of Entourage and Quicken.
but the arrow keys I do not recall being an issue.
What you can try is to go to Users/Username/Library/Preferences/Adobe Illustrator (version number) Settings folder and thras that folder first quitting Ilustrator.
Or if that is not working see if you create a new user account and log into that aaccount and see if the problem still exist if not then there is probably a conflict of somekind you will do best then to do a search on the forum or google for Arrow keys do not work in your version of Illustrator
youy should always give more information lkike what version of AI or if you have plug ins or installed new fonts or plug ins or other software or updates.

I just looked in Google for the answer to this too. I tried to nudge an object and nothing happened. Well my problem was in Preferences - General - Keyboard Increment had somehow been set to zero. I put in 1 px and it's back to normal now :-)
Thank you so much your solution for arrow keys not working did the trick. The apple store meant well and they are usually awesome but misinformed me in one to one saying my computer did not have the capacity to make the arrow keys work. I tried the solutions suggested from several posts including command alt shift at opening of Illustrator to command P + R . None of those solutions worked. Your solution did. Thank you!
Hello. I have this same problem since my last update in Illustrator CC. Objects won't move anymore when using my arrow cursors. In my settings, it seems that all is ok, but it won't move. Does anybody know of any other setting i could check? In the other Adobe apps, i don't have this problem. My arrows are working in Indesign & Photshop, just not in illustrator.
I'm with the same problem
For me, it was actually resolved with the latest update, so my illustrator is working fine now
