The Geolocation control uses Google Maps v3, and as of june 22, 2016 Google no longer supports keyless access, so you need to get a key for every (referrer)-domain which has never had a Google Map on it before.
Get your key here: https://developers.google.com/maps/documentation/javascript/get-api-key
Alternatively, you can specify a single Google API key for all Google related services using the appSetting google.apikey.
