I have just been on a support chat with EA about this exact issue after buying the game for my PC.
Eventually the answer is:
SurajI would like to share that in order to work properly you will need at least a keyboard and a controller
SurajIt must identify another controler .
SurajThe keyboard is being identified as one player , but there should be another controller to be identified as second player.
SurajI am afraid to say that to play locally the game needs to identify both the players as there are multiple controls in the game .
So, in short if you want to play locally with 2 people on the same PC you need a controller of some kind for the second player.
Additional response from EA when I asked them why they didn't allow use of the same keyboard with different keys mapped for each player:
SurajThis has been tested on one keyboard and there were lot of issues .
