Frequently Asked Questions
Find answers to the most common questions about our products, delivery, activation, and support.
About Our Products
Yes. Every key is a genuine Microsoft product key that activates on Microsoft's own activation servers, and every key is covered by our activation guarantee. Each product page tells you the key type (Retail, OEM, Bind Key, phone activation or volume license) and exactly how it activates.
OEM (Original Equipment Manufacturer) keys are tied to the first computer they are activated on and cannot be transferred to a different device. They are more affordable because of this restriction.
Retail keys can be transferred to a new computer if you deactivate the old one first. They offer more flexibility and are ideal if you plan to upgrade your hardware in the future.

Online Keys are activated through Microsoft's online activation portal or by phone. The key is entered during installation and verified through Microsoft servers.
Bind Keys are linked directly to your Microsoft account. Once bound, the license is tied to your account and can be managed from your Microsoft dashboard. Bind Keys are generally more secure since they're protected by your account credentials.

Most products on Keys Locker are one-time purchases — you pay once, with no subscription, and use the software for as long as it is supported by Microsoft. This includes all Windows, Office 2016/2019/2021/2024, Visio, Project, and Server products.
The exception is Microsoft 365 (formerly Office 365), which is a subscription-based product. Microsoft 365 licenses are sold for a specific period (e.g., 1 year) and must be renewed to continue using the software. Each product page clearly indicates whether it is a one-time purchase or a subscription.

Yes. Once activated, your software will receive all official updates (security patches, bug fixes, and feature improvements) as long as the product is supported by Microsoft. For example, Office 2021 is supported until October 2026, and Windows 11 receives ongoing updates.
Only products specifically marked as Mac-compatible in the product title will work on macOS (e.g., "Office 2021 Home & Business — Bind Key (Mac)"). Windows operating system keys only work on PCs. Always check the product title and description for platform compatibility before purchasing.
Ordering & Delivery
Usually instantly, and at most a few minutes depending on demand and stock. Your key appears on your order page as soon as your payment is confirmed, and we email you a link to it. The key stays hidden until you click Reveal key. Your order page also has the installer download, where we provide one, and a step-by-step activation guide.
First, open your order page: your key appears there as soon as it is ready. Then check your spam/junk folder for our email with the link, and make sure the email address you entered at checkout is correct. If you still can't find it after 15 minutes, contact our support team and we'll sort it out right away.
We accept credit/debit cards (Visa, Mastercard, American Express), Apple Pay, Google Pay, pay-later with Klarna or Affirm, cryptocurrency, and other secure payment options available at checkout. All transactions are processed through encrypted, PCI-compliant payment gateways.
Absolutely. Our website is protected by SSL encryption, meaning all data transmitted between your browser and our servers is fully encrypted. We never store your credit card details and follow industry-standard security practices to protect your information.

Your order page has the installer download (where we provide one) and a link to the step-by-step guide for your product. Generally:
For Windows: Go to Settings → System → Activation → Change product key, enter your key, and click Activate.
For Office: Download from the official Microsoft website, install, open any Office app, and enter your product key when prompted.

This is usually caused by one of these issues:
• Edition mismatch — e.g., trying to activate a Pro key on Windows Home. Make sure your installed edition matches the key.
• Old software remnants — Previous Office installations can interfere. Uninstall old versions first.
• VPN/Proxy interference — Disable any VPN or proxy and try again.
If the issue persists, contact our support team with your order number and a screenshot of the error. We'll help you fix it, or send a free replacement within 24 hours — or a full refund if we can't replace it.

Yes! If you reinstall on the same computer, your key will work again. For Retail keys, the license is often automatically recognized after reinstalling. For OEM keys, activation should work as long as you're using the same hardware. Bind Keys tied to your Microsoft account can be re-downloaded from your account dashboard.
It depends on the key type:
• Retail keys — Yes, you can deactivate on the old PC and activate on a new one.
• OEM keys — No, these are permanently tied to the original hardware.
• Bind keys — These are tied to your Microsoft account. Contact Microsoft support for transfer assistance.

Refunds & Support
Your key stays hidden on your order page until you click Reveal key. If you haven't revealed it, you can cancel within 14 days of purchase for a full refund. Once you reveal it, the sale is final unless the key is defective: then we send a free replacement within 24 hours, or a full refund if we can't replace it. Problems installing with Microsoft's installer aren't a key defect, but we'll gladly help you install. See our Refund Policy for the details.
So you can still change your mind. Until you click Reveal key, nobody has seen your key, so you can cancel within 14 days for a full refund. Once you reveal it, we can't take it back, so the sale is final unless the key doesn't work.
You can reach our support team through the Contact Us page on our website or by emailing us directly. We aim to respond to all inquiries within a few hours. For activation issues, please include your order number, product name, and a screenshot of the error to help us resolve it faster.
