[javascript] How to use google maps without api key

Hi i am using this code to use get-directions in google maps. but when i run this from other machines it is showing the error invalid api key. how to use this same map without an api key.

<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=false&amp;key=ABQIAAAAuPsJpk3MBtDpJ4G8cqBnjRRaGTYH6UMl8mADNa0YKuWNNa8VNxQCzVBXTx2DYyXGsTOxpWhvIG7Djw" type="text/javascript"></script>
    <style type="text/css">
    body {
      background:#FFE1C7;
      font-family: Verdana, Arial, sans serif;
      font-size: 11px;
      margin: 2px;
    }
table.directions th {
      background-color:#EEEEEE;
    }

    img {
      color: #000000;
    }
    </style>
    <script type="text/javascript">

    var map;
    var gdir;
    var geocoder = null;
    var addressMarker;

    function initialize() {
      if (GBrowserIsCompatible()) {      
        map = new GMap2(document.getElementById("map_canvas"));
        gdir = new GDirections(map, document.getElementById("directions"));
        GEvent.addListener(gdir, "load", onGDirectionsLoad);
        GEvent.addListener(gdir, "error", handleErrors);

        setDirections("Bangalore", "Mysore", "en_US");
      }
    }

    function setDirections(fromAddress, toAddress, locale) {
      gdir.load("from: " + fromAddress + " to: " + toAddress,
                { "locale": locale });
    }

    function handleErrors(){
     if (gdir.getStatus().code == G_GEO_UNKNOWN_ADDRESS)
       alert("No corresponding geographic location could be found for one of the specified addresses. This may be due to the fact that the address is relatively new, or it may be incorrect.\nError code: " + gdir.getStatus().code);
     else if (gdir.getStatus().code == G_GEO_SERVER_ERROR)
       alert("A geocoding or directions request could not be successfully processed, yet the exact reason for the failure is not known.\n Error code: " + gdir.getStatus().code);

     else if (gdir.getStatus().code == G_GEO_MISSING_QUERY)

    //   else if (gdir.getStatus().code == G_UNAVAILABLE_ADDRESS)  <--- Doc bug... this is either not defined, or Doc is wrong
    //     alert("The geocode for the given address or the route for the given directions query cannot be returned due to legal or contractual reasons.\n Error code: " + gdir.getStatus().code);

     else if (gdir.getStatus().code == G_GEO_BAD_KEY)
       alert("The given key is either invalid or does not match the domain for which it was given. \n Error code: " + gdir.getStatus().code);

     else if (gdir.getStatus().code == G_GEO_BAD_REQUEST)
       alert("A directions request could not be successfully parsed.\n Error code: " + gdir.getStatus().code);

     else alert("An unknown error occurred.");
    }

    function onGDirectionsLoad(){
        // Use this function to access information about the latest load()
        // results.

        // e.g.
        // document.getElementById("getStatus").innerHTML = gdir.getStatus().code;
      // and yada yada yada...
    }

    </script>

Can anyone help me...thanks in advance..

Hey You can Use this insted

<iframe width="100%" height="100%" class="absolute inset-0" frameborder="0" title="map" marginheight="0" marginwidth="0" scrolling="no" src="https://maps.google.com/maps?width=100%&amp;height=600&amp;hl=en&amp;q=%C4%B0ikaneir+(Mumma's%20Bakery)&amp;ie=UTF8&amp;t=&amp;z=14&amp;iwloc=B&amp;output=embed" style="filter: scale(100) contrast(1.2) opacity(0.4);"></iframe>

this simple code work 100% all you need is changing 'lat','long' for address to show

<iframe src="http://maps.google.com/maps?q=25.3076008,51.4803216&z=16&output=embed" height="450" width="600"></iframe>

Now you must have API key. You can generate that in google developer console. Here is LINK to the explanation.

source

In June 2016 Google announced that they would stop supporting keyless usage, meaning any request that doesn’t include an API key or Client ID. This will go into effect on June 11 2018, and keyless access will no longer be supported

You can still use free with iframe in google maps share button for example
