# Error 403 “Invalid key” when accessing the service with the key obtained in the Developer Dashboard

If you've received this error, please try the following:

- Check that the key was actually registered by you and for your site.
    
- Check that you actually linked this key to the service you are trying to access.
    
- Check that you entered your key correctly: does it include any spaces or extra characters?
    
- For paid or pre-moderated API services, a contract for using the key must first be concluded or its use approved. Check your email: we always send a notice when creating such keys. In the detailed information about the key, you should see its activation steps.
    
- Check that the key isn't blocked. To do this, select the key and its service. If the key was blocked by you, unblock it.
