A ceiling fan motor shouldn't lock up especially after only two years. In this case, the best first step would be to contact the manufacturer. If that goes no where then you'll probably have to replace the unit. Unless you are skilled at making these types of repairs you don't typically want to try to make any changes to the motor as this is where all the movement, energy, heat, etc. is and something done incorrectly could lead to serious problems.
