Important Note

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 Contacting VALVe Billing and Support article for instructions to retrieve your lost Steam account if it is possible that you may have registered your CD Key in the past.

CD Key Reset Process Guidelines

If you recently purchased a copy of a game which requires activation on Steam and are encountering a "Duplicate CD Key" error message you will need to contact us to have the CD Key reset so you may use it.

Note: We cannot 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 your CD Key matches the ##### - ##### - ##### - ##### - ##### pattern you must have a copy of your recent purchase receipt to have the CD Key reset.

Sierra Half-Life, Counter-Strike, and Blue Shift CD Keys

Older CD Keys (Sierra Half-Life, Counter-Strike, and Blue Shift CD Keys) are printed in the following format:

#### - ##### - ####

If your CD Key does not match the pattern (4 numbers - 5 numbers - 4 numbers), please skip down to the All Other CD Keys section.

If your CD Key matches the #### - ##### - #### pattern and you are certain that you have not registered it over Steam in the past, please mail the following items to us for review:

1. The original printed CD Key - no copies, photos or scans of the CD Key will be accepted. Please send only the CD Key - do not send the game box or game CDs
2. A completed copy of the CD Key Reset Form (you do not need to complete any fields which you do not have the information to complete)
3. A photocopy of your receipt for the purchase of the game if the game was purchased within the last 90 days (please circle the game title on the photocopy if there are multiple items on the receipt)
4. If you do not have a copy of your receipt for the recent purchase of the game, please include a money order or bank cashier check made out to Valve Corporation for $10.00 USD (ten dollars in United States funds) to pay the CD Key Reset Service Charge

Please print out the completed CD Key Reset Form (do not print out an incomplete copy and fill in the fields by hand). Specify the use of any numbers in the names or email accounts. For instance, "B0B" has the number zero in it; you would need to point this out to us.

Package and send the requested materials to:

CD Key Reset
Valve Corporation
PO Box 1688
Bellevue, WA 98009
USA

Your CD Key will be sent back to you via US Mail once it has been reset. Please allow 6 to 8 weeks for the materials to be mailed back.

Note: You do not need to wait to receive your CD Key from us to make use of the subscription on your Steam account – you will be sent an e-mail regarding the status of your CD Key reset request when your request is received and processed.

All Other CD Keys

Current CD Keys are comprised of 18 numbers and letters (Prey) or 25 numbers and letters (Valve games) arranged into five groups of five characters separated by hyphens:

Prey example:

If your CD Key fits one of these patterns, please see the Contacting VALVe Billing and Support article for instructions to create a support case to 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 auction sites or in cases in which the game has been resold by another individual)
• The Steam account username you would like the CD Key moved to

CD Key Scan Example

Please see the example below to see how your CD Key image should be sized and noted. Please write your account name - in the example you will see the account name "support" - or your support incident number (you will need to submit your incident, write your incident number on the CD Key, and then update your case with the scan if you are not sure of your account name).

If you do not have access to a scanner or digital camera, you may complete the CD Key reset process described for Half-Life, Counter-Strike, and Blue Shift CD Keys which is outlined above (you do not need to include $10.00 USD for the CD Key Reset Service Charge).
