I guess there is something with your settings of security, There might be an option that is asking you an code to unlock the phone which has been enabled and the time limit of the lock must be set to the 120 min interval. Then what you have to do is just go to the settings and just disable the lock. What it will do is not only remove the code lock but also the automatic lock.
