An exemplary heatable keypad assembly includes, among other things, a touch-sensitive sensor providing a keypad, and a heating element that includes a conductive polymer-based material and is disposed adjacent the touch-sensitive sensor. An exemplary keypad heating method includes, among other things, holding a heating element having a conductive polymer-based material near a touch-sensitive sensor. The touch-sensitive sensor provides a keypad adjacent a transparent panel of a vehicle. The method further includes activating the conductive polymer-based material to heat an area of the transparent panel adjacent the keypad.
