Redeeming your key
Open Steam and log in. Click Games in the top menu, then Activate a Product on Steam. Paste your key exactly as delivered — including dashes — and follow the prompts. Your game appears in your library immediately and can be installed right away.
Common errors
Invalid product code: double-check for mixed-up characters like 0/O or 1/I. Not available in your country: the key has a region restriction — check the region badge on your order page and contact support if it does not match your location.
