Well, I'd doubt it's locked to a single save because you don't even need to load a save to redeem the key, and after redeeming the item appears on your Steam inventory, so I'd say the game getting updated wouldn't really change a thing. It's on your Steam inventory, so you can probably uninstall the game, delete all data and then reinstall and you will still have the item.
