Google Maps V3 API Key Invalid - but my personal dev key works

Question

I had a number of reports from clients about problems with Google maps on their sites. I checked and got "Invalid key" errors.

Strangely, Google used to give out keys with a space before and after the API key. In the past, when I left the spaces off, the key broke. It was frustrating to remember to leave those spaces.

Now, I trim() my current API Key (with or without spaces) before submitting it to Google Maps and it works.
