Questions before you buy
Short answers to what buyers ask us most.
Are cheap software keys legit?
Our keys are retail licenses bought as surplus from companies that buy in bulk. You download the software from Microsoft and activate it online with the key. If a key doesn't activate, we fix it, replace it or refund you within 15 days of your order.
Why are your keys cheaper than Microsoft's?
We buy surplus licenses from companies that bought more than they need, and sell them as digital keys: no box, no shipping and no subscription.
How fast will I get my key?
The key is sent by email right after payment and saved in your account. Rarely it takes 5–10 minutes.
What if my key doesn't work?
Contact us on live chat or at support@cheapkeys.io. We fix it, replace the key or refund you within 15 days of your order, as our refund policy explains.
Do I need a subscription?
No. Office 2024, 2021, 2019 and 2016 and Windows keys are one-time purchases. Microsoft 365 and antivirus run for the period shown on the product.
Can I move the key to another PC?
Windows keys and Office Professional Plus keys are for one PC: you can reinstall on the same PC, but not move the key to a new one. Office Home and Home & Business are tied to your Microsoft account, so you can change devices.
