Can I still activate and play The Elder Scrolls V: Skyrim (Key) on Steam?

General:

I would like to play The Elder Scrolls V: Skyrim on my notebook. Unfortunately, I've heard from Steam that you no longer offer the game "The Elder Scrolls V: Skyrim" for sale. Only the Special Edition (Remaster) offer them.

So I want to buy a key from The Elder Scrolls V: Skyrim on MMOGA to enable the game on Steam.

Following question:

Can I redeem the key despite a sell stop on Steam?

And can I play the game then?

Info:

I do not want to buy the Special Edition (remaster) because my notebook does not work. (System requirement)

Notebook info:

CPU: I5 7200u

RAM: 8G

Graphics card: AMD Radeon R7 m340 (2G)

Windows 10 Pro

240G SSD / 1TB HDD

This should not be a problem. Because the key for the normal Skyrim is already at the shop. That's why it should work

Thanks for your answer and your help.

Yes only mods do not go.

Thanks for your answer and your help. I do not need mods.

Jap, in general, you can still activate all keys, whether the game is available in the Steam Shop or has already been taken out does not matter.
