Does Geocoder gem work with google API key?
===

I am using ruby geocoder gem for my project and as the project is growing I am starting to look into connecting to the Google API key. After adding this to the project:

    Geocoder.configure do |config|

    # geocoding service (see below for supported options):
    config.lookup = :google

    # to use an API key:
    config.api_key = 'my_key'

    # geocoding service request timeout, in seconds (default 3):
    config.timeout = 5

    end 

I get Google Geocoding API error: request denied. when I start the application. From reading around, it seems like others switch over to yahoo if they choose to continue using the gem. Can I configure the gem to work with google api key? Mainly, I would like to keep an eye out for the amount of daily queries to avoid going over the limit.
