Sims 4 without a disk?

I bought Sims 4. I would have to put the disc in my drive, but since my laptop is new I don't have one anymore. I have the key, can I just download it with the key?

The key is for the installation that goes with the help of the disc. Unless it's a key for Origin

Yes with Origin you just give the key as a code

So it won't work without me inserting the disc?

It certainly has a key for Origin, you don't need to insert the disc for that. Or it is this one, so I do not think that nowadays no key can't be redeemed even without the CD
