Bernard Mendy once again came handy as he scored the opening goal for the visitors in the 22nd minute.
The lead was canceled out in the 66th minute when Didier Kadio scored. Local boy CK Vineeth gave the hosts lead in the 85th minute from a counter-attack.
Vineeth scored the third goal for his team within 4 minutes to seal the match in Kerala's favour.
Kerala move up to second position in the league table just behind Delhi Dynamos. Chennaiyin, on the other hand, are struggling at the seventh position.
