Note that if you have not yet paired your key with a Google account the page will say "No action needed". Apparently they try to detect if the key is paired with your account before they replace it. I emailed them to the contact address on that web page, but no reply just yet. I hope they have a return/replace workflow for unused keys because obviously, why would you want to use one before you get it replaced? Obviously.
