GoogleMaps API -address to coordinates (latitude,longitude)

Question

This is driving me crazy. I have deleted this key 1000 times so far. Yesterday it worked like a charm, today not anymore Here is the python code:

from googlemaps import GoogleMaps
gmaps = GoogleMaps("AIzaSyBIdSyB_td3PE-ur-ISjwFUtBf2O0Uo0Jo")
exactaddress ="1 Toronto Street Toronto"
lat, lng = gmaps.address_to_latlng(exactaddress)
print lat, lng

GoogleMapsError: Error 610: G_GEO_BAD_KEY

It is now returning the above error for no obvious reasons. I don't think I have reached the request limit or the maximum rate To stay on the safe side I even introduced delays (1sec) ...stil getting the same error

Does anybody have any idea how I can solve this? Having to work with a different python module is fine if you can indicate an alternative to the one that I am currently using.

thanks C

PS: the key is valid, it is a client key and it was automatically enabled when I enabled GoogleMAP API3 in the App console. No restrictions for domains or IPs

EDIT: So here is what I ended up using

def decodeAddressToCoordinates( address ):
        urlParams = {
                'address': address,
                'sensor': 'false',
        }  
        url = 'http://maps.google.com/maps/api/geocode/json?' + urllib.urlencode( urlParams )
        response = urllib2.urlopen( url )
        responseBody = response.read()

        body = StringIO.StringIO( responseBody )
        result = json.load( body )
        if 'status' not in result or result['status'] != 'OK':
                return None
        else:
                return {
                        'lat': result['results'][0]['geometry']['location']['lat'],
                        'lng': result['results'][0]['geometry']['location']['lng']
                }  

The library that Jason pointed me to is also interesting but since my code was intended to fix something (one time use) I have not tried his solution. I will definitely consider that if I get to write code again :-)

Although Google deprecated the V2 calls with googlemaps (which is why you're seeing the broken calls), they just recently announced that they are giving developers a six-month extension (until September 8, 2013) to move from the V2 to V3 API. See Update on Geocoding API V2 for details.

In the meantime, check out pygeocoder as a possible Python V3 solution.
