A keyless entry assembly for a vehicle includes a sensor carrier, a sensor in the form of an electrically conductive pad, and a controller. The sensor is mounted to the sensor carrier and the sensor carrier is positioned adjacent a panel such that the sensor is adjacent the panel. The sensor capacitively couples to an electrically conductive object proximal to the panel while the sensor is driven with electrical charge such that capacitance of the sensor changes due to the sensor capacitively coupling with the object. The controller is operable for driving the sensor with the electrical charge and controlling a vehicle operation as a function of the capacitance of the sensor.
