Bought the wrong key without noticing
Bought the wrong key without noticing. Asked for help and was immediately given a new key at no additional cost. Excellent customer service.
got usable replacement key
got a replacement key that worked after getting a unusable key
The key didn't work
The key didn't work, so I guess I just got scammed for 25 bucks. Feelsbad.
Edit: I don't know how to reply on this. I rounded up, the key I bought was actually $23 I believe. I'll send you an email after work, but yes the key I entered was invalid according to the computer

Very happy with the experience!
Bought a Windows 10 Pro license key and received the license key in my inbox almost immediately. I followed the instructions to enter the key to upgrade from 10 Home to Pro, but it didn't work. I kept getting an error. I contacted Cdkeynz's support team via FB chat on their website, and they helped me work around the issue very quickly. Just had to restart my laptop and re-enter the key again and Microsoft successfully activated the new license. Very happy with the experience!
Quick transaction and delivery
I ordered a Windows 10 Pro key. The transaction was quick. The key was delivered immediately, and worked.
Updated review….. Wow, this company is great!
I paid full price for the windows 10 pro key and the key doesnt work. I might as well just never use this website again. What a waste.
Updated: within minutes I got a response and got a new key. I underestimated these guys but won’t ever again. Just want to thank them for being so swift on making things right.
After receiving the key
After receiving the key, I upgraded the window version to Win 10 Pro and installed the SQL 2019 successfully. The key works well.
Thank for the installion video. I also checked for more video on yourtube.
Great Customer support
The customer support is amazing they reply fast and are willing to help you with your problem will definitely come again for anything I need to buy.
VERY good customer support.
Some of the best customer support i've ever experienced.
great customer service
My initial key wasn't working and they replaced it for me no problem!
Great customer service
Ordered my CD key, had an issue with it, and I wrongfully posted a negative review. Within minutes their team reached out to me and resolved the issue right away. I was angry, they made it right. And now I feel much better. Thank you, I will be buying from you again in the future!
BEST COMPANY EVER
At first, I left a bad and unfair review. I was immediately contacted by CD Key to see what the issue was. Unfortunately, I purchased the wrong product key. I MADE THE MISTAKE! Their customer service rep was kind, polite, and EXTREMELY helpful in resolving this issue for me! My Windows 10 Pro is not activated without having to make a single phone call or file a return. I could not recommend any company more than CD Key when shopping for product keys solely based on customer service alone. Secondly, pricing is amazing! Do your homework and don't make the same dumb mistake I did before leaving a bad review. They deserve a great review for every purchase. I am grateful for everything they did for me. It only took 5 minutes to fix.
Excellent process and pricing
