A further input state is an intermediate unlocked state in which a limited operational use of the input portion is possible; which method comprises entering the intermediate unlocked state from the locked state, based on user input; detecting termination of a user operation in the intermediate unlocked state, and entering the locked state, in response thereto. There is also provided an input controller, a keypad and a mobile electronic device implementing these features.
