Unregister a cd-key / Terminate access to a subscription

[76561197992339946]

Hi.
I want to unregister the cd key of a half-life box.
I have not found how to do it.
I have also tried to contact the steam support but have not found it.

you can not. Once bound to an account, it is permanent.

According to the user agreement you can, even if later the cd-key won't be registerable again.
Actually the games provided by this half-life pack are provided by another pack that i have later bought.

You can go to the SUPPORT page, select the game and choose " i want to permanently remove this game from my account".
This will remove it from your library and your games list.
BUT , it can be restored the same way any time you want in the future.
You can also buy it anew if you want but if you do you will get the same serial key assigned as before.

I have found 2 lists of games in support page.
One with the list of games i have purchased (the pack doesn't appear here);
One with the list of games i have registered with cd-key. The pack appears here but i didn't see any option for unregistering it.

Because there is no way to unregister a product key. Once it is used it is permanently bound to your account.

And what if for i lose my physical half-life box?
Doesn't this terminate my licence for the games?

No. Once activated the game is forever bound to that account. As long as you have the login data for that account you can forever download and play that game.
After activation the retail case is basically just a piece of plastic with no use except to display on a shelf maybe.

Why would it?

Really, the physical boxes for Steam-games are just worthless trinkets. The only thing you shouldn't loose, if possible, is the sheet with the key -- simply because Steam support considers such "physical keys" to be high-value proof of account ownership.

The box I have registered is from the area where the disc contained the game that can be installed without steam.

As others have already stated. Product keys are bound to the account permanently.
You cannot revoke the key to use on another account or give to another user etc etc.

The "Permanently remove" option is a glorified hide button. There is also 0 point in removing the original Half-Life CDKey. You also need this for support in case of an issue. I didn't keep mine and I'm having one heck of a time with support now.
