CD Key Reset Process
Question
I receive a "Duplicate CD Key" message but I am sure that I have never activated this CD Key on Steam. What should I do?
Answer
Important:
A CD Key may only be registered to one Steam account. CD Keys are associated with your Steam Account, not your computer.
Please see the Resetting a Lost Password article for instructions to retrieve your lost Steam account if it is possible that you have registered your CD Key in the past.
CD Key Reset Process Guidelines
If you recently purchased a new retail game which requires activation on Steam and are encountering a "Duplicate CD Key" error message, you must contact Valve to have the CD Key moved to your account. Please contact us through our online support system as outlined here:
Contacting Steam Billing and Support
You must have a copy of your valid purchase receipt from within the last 90 days to have the CD Key moved to your account.
Note:
We do not accept receipts from online auction websites or used software vendors. If you do not provide a valid purchase receipt, Valve will not be able to transfer the CD Key.
We do not reset CD Keys which have been disabled for violations of the Steam Subscriber Agreement and/or End User License Agreement or banned by VAC for cheating infractions.
If you still need assistance in activating your CD Key, please follow this link to create a support case and provide the following materials:
* A scan or digital photo of the CD Key with the words Reset To and your Steam account username written in permanent ink on the reference card or sticker (without obscuring the CD Key)
* A scan or digital photo of your retail purchase receipt (game must have been purchased within the last 90 days - we do not accept receipts from online auction websites or used software vendors)
CD Key Scan Examples
If you are unsure of what CD Keys are used on Steam, please see this guide
Here is a typical example of a CD-key reset attachment. Please write your account name or support incident number on the reference card. (If you do not have your account name, you must first create your support ticket, copy the incident number then submit an update to the ticket with your digital photo of the CD-key.)
