Using google maps without API Keys?

Question

I am developing a CMS that will use more than one domain and I have to use only one google map script in my page.

Is there a way to use google maps without API key?<

Answer 1

This is possible with any version of the Google Maps API, as described here. Basically the only thing the map actually does if used without a key is display an alert complaining about it. If you trap the alert and prevent it from being displayed, the map will function as normal.
