Adding a Google map layer to Openlayer. What is the requirement?

Question

I have been using google map layer with my application since a year, and suddenly it stops working. Is a Key required to use the google map API? My code is as follows.

map = new OpenLayers.Map('mapDiv');
map.addControl(new OpenLayers.Control.LayerSwitcher());

var gphy = new OpenLayers.Layer.Google(
    "Google Physical",
    {type: google.maps.MapTypeId.TERRAIN}
);
var gmap = new OpenLayers.Layer.Google(
    "Google Streets", // the default
    {numZoomLevels: 20}
);
var ghyb = new OpenLayers.Layer.Google(
    "Google Hybrid",
    {type: google.maps.MapTypeId.HYBRID, numZoomLevels: 20}
);
var gsat = new OpenLayers.Layer.Google(
    "Google Satellite",
    {type: google.maps.MapTypeId.SATELLITE, numZoomLevels: 22}
);

map.addLayers([gphy, gmap, ghyb, gsat]);

// Google.v3 uses EPSG:900913 as projection, so we have to
// transform our coordinates
map.setCenter(new OpenLayers.LonLat(10.2, 48.9).transform(
    new OpenLayers.Projection("EPSG:4326"),
    map.getProjectionObject()
), 5);

I have nested the whole script library. If one day I select Google Satellite, and then try to use Google Streets or another option than Maps to download the application.
