Hi, it has worked fine, but it says "Demon Protocol for Beta Testing". Just letting you know in case the game is removed from library. So far it seems to work fine.

Hi, the key is also for beta testing for the same game I already activated. Afaik, if they are dev keys the game will stay in my library. You can use the key, since I didn't activate it.
This is the message from Steam with the replacement key:
